  • 2:35 - 2:55 – Accelerated Aging of Rejuvenated Cables
    Glen J. Bertini, Novinium Inc.
    Abstract: This paper provides a framework for the prediction of the effective life extension of cables treated with rejuvenating chemicals under accelerated aging conditions. Utilizing the principles of molecular thermodynamics and a cable’s soil regime, soil thermal conductivity, and load profile, it is possible to make accurate estimations of life extension for legacy technologies and for new advanced technologies.
  • 2:55 - 3:15 – Advances in Manufacturing Technology for Ethylene-Propylene Elastomers
    Kent L. Chasey, ExxonMobil Chemical Company
    Abstract: Ethylene-propylene elastomers are considered in this presentation to include two types of ethylene-based polymers: EPMs (copolymers of ethylene and propylene), and EPDMs (terpolymers of ethylene, propylene, and a nonconjugated diene). Since commercialization in the early 1960s, worldwide demand for ethylene-propylene elastomers has grown consistently and now approaches 1.9 billion pounds per year. Ethylene-propylene elastomers are the preferred polymers in a wide range of thermoset applications, including filled solid dielectric cable. Certain inherent properties of these polymers, such as excellent resistance to aging, are very beneficial. In addition, optimizations of EPM and EPDM products have occurred through a variety of advances in manufacturing technology. Highly-engineered polymers are now available to meet the processing and performance needs of many end-uses. This presentation will review some of the significant advances in manufacturing technology during the past forty years. The newest manufacturing platform for production of ethylene-propylene elastomers is based on metallocene catalysis, and this technology will also be discussed.
  • 3:15 - 3:30 – Break
  • 3:30 - 3:50 – Field Aging of Ethylene-Propylene Rubber (EPR) Dielectric Cables under “Normal” and “Accelerated” Voltage Stress at Memphis Light, Gas and Water
    Phillip Cox, Memphis Light, Gas and Water.
    Abstract: Memphis Light, Gas & Water in 1980 changed its underground cable specification to EPR insulated cables from PE insulated cables due to the high failure rate being experienced. This presentation describes the project criteria and alternating-current breakdown test results from field aged EPR URD type cables. These cables have been field aged under “normal” and “accelerated” voltage stress. This is an interim report ( 9 to 14 years service life), with additional testing planed when the field aged cables reach 20 years of service.
  • 3:50 - 4:10 – Development of a Cable Flexibility Model
    K. Yang, T.J. Person, P.J. Caronia, L.H. Gross, The Dow Chemical Company
    Abstract: A finite element computer modeling effort was used to simulate the influence of material properties on the flexibility of a cable. The key material properties used in the model and the predicted stress distribution within the cable as it is bent around a mandrel will be presented. The model predictions were compared to actual cable bending tests. Further utilization of the model can enable predictions of cable flexibility due to design changes in cable constructions.
  • 4:10 - 4:30 – Laminated Copper Sheaths in Medium and High Voltage Cables
    Kenneth E. Bow, Kable Consult, LLC, Yimsan Gau, The Dow Chemical Company
    Abstract: Laminated sheaths with coated copper have found increased use in medium and high voltage cables because they offer a very viable alternative to other metallic sheaths, especially lead and pipe-type cable with oil filled paper insulation. In both medium and high voltage (MV and HV) cables, a 0.15 mm (6 mils) thick copper coated on one side can be used as moisture and chemical barrier over the cable core. In the cabling process, the coated copper tape is folded longitudinally over the cable core, sealed with a hot melt adhesive at the overlap and bonded to the extruded cable jacket. The combination of bonded jacket and sealed seam acts as a metal lined plastic pipe with excellent barrier to chemical and moisture ingress. Experience to date has shown that MV and HV cable designs with laminated copper sheaths and insulated with XLPE offer excellent reliability and ease of installation. The paper describes an overview of the product development of coated copper tape and its applications in MV and HV applications.
  • 4:30 - 4:50 – 115 kV Underground Power Cable Systems in México: The Laguna Project
    Candelario de J. Saldivar Cantu, Conductores Monterrey.
    Abstract: The most ambitious 115 kV cable system up to date in México was installed in the north central part of the Country and started operations during the last quarter of 2004, as a part of the CFE distribution system. In this presentation is described the system configuration, the cable design, aspects of the cable and accessories installation and the field tests performed to the system.
  • 4:50 - 5:10 – Self-Sealing Cables: State-of-the-Art Evaluation
    Frank Doherty, Consolidated Edison Company, Bruce S. Bernstein, Consultant.
    Abstract: A state-of-the-art survey of low voltage self-sealing cables is described. The objective was to assess and evaluate the best practices of technology to prevent aluminum conductor corrosion. Nine utilities and four manufacturers were interviewed. Two manufacturers provide the cable constructions of interest and have had their products evaluated by NEETRAC. Each utility is at a different stage of the evaluation process. It is concluded that the technology for sealing a defect developed prior to, during or after installation is technically sound as determined by aging and leakage current studies. Handling issues during installation differ for the different cables. Considerations for users include (a) initial and life-cycle costs, (b) installation, handling and labor, (c) potential environmental issues and (d) monitoring cable performance over time.
  • 5:10 - 5:30 – Tolerance to Conduction Defects in Transmission Class Solid Dielectric Cable
    Zhong Zheng, University of Toronto, Steve Boggs, University of Connecticut.
    Abstract: Considerable experimental work has been carried out to gain insight into the tolerance of transmission class solid dielectric cable to conducting defects; however, a scientific basis for predicting such tolerance has been lacking. We will present a theoretical and computational basis for predicting such tolerance along with predictions of the worst case tolerable defect as a function of operating electric field and temperature. The resulting predictions are in general agreement with present conventional wisdom based on experimental evidence and engineering judgment.
  • 5:30 – 5:35 – Meeting Adjourn
    Serge Pélissou, John Smith III
• Subcommittee B - Accessories - Monday, April 18th, 2:00 pm - 5:30 pm
  • Upcoming Changes in IEEE 404, Joints, and IEEE 48, Terminations
    Rick Hartlein, NEETRAC
    Abstract: Work is underway on significant revisions to both the IEEE 404 standard on cable joints and the IEEE 48 standard on terminations. New test procedures are being added and efforts are underway to align requirements between the two standards. Some of the issues that will be addressed in the presentation include: (1) a new sealing test for terminations, (2) cable jacket restoration and metallic shield restoration for joints, and the possible future inclusion of (3) requirements for a long-term aging test.
  • Comparison of Narrow Band and Wide Band PD Measurements in the Case of Reference Defects in the Fitting of Accessories
    Pierre Mirebeau, C Fabre, P. Deguines, F. Gahungu of Nexans; F. Puletti of Techimp
    Abstract: 50 years of practice has led to well established knowledge rules for narrow band PD measurements – tests are performed according to IEC 60270. On the other hand, on-site PD checking of the fitting of accessories is more and more part of the commissioning tests of very high voltage links. Because of the poor signal to noise ratio in the case of narrow band PD measurements, wide band PD measurements have been developed. The authors compare Narrow band and Wide band PD measurements in the case of reference defects in the fitting of accessories, showing the effects of bad positioning and bad surface preparation.
  • Corrosion Induced Failures of Shield Connections on Power Cables Using Longitudinally Corrugated Shields
    Thomas Champion, NEETRAC
    Abstract: A variety of methods exists for making shield connections across joints or at terminations on power cables using longitudinally corrugated metallic shields. These connections generally depend on some form of mechanical clamping to ensure contact. If moisture manages to enter the cable shield area as a result of jacket damage or a poor seal at a joint or termination, moisture can end up in the shield connections, creating corrosion and leading to a connection failure. Opportunities exist for improving this connection to eliminate this problem.

  • 8:15 - 8:45 - Crossing the Interstate: A 69 kV Underground Installation
    Mike Poucher, Ocala Electric Utility, FL
    Abstract: Ocala Electric Utility installed its first underground 69 kV cable system to cross Interstate 75 in 2004. This presentation focuses on the decision making process that led to the installation from the selection of a route to the final installation and testing of the cable. Significant highlights include justification for selecting underground construction, decisions on the long-term maintenance of the cable, unforeseen challenges and their resolution in the construction phase of the conduit bank, and the final installation and testing of the new cable installation.
  • 8:45 - 9:15 - New 380 kV Transmission Line in Vienna: Changing from 380 kV Oil-Filled to XLPE Cables
    Ernesto Zaccone, Pirelli
    Abstract: The fashionable old European city of Vienna has an average electric power demand that is increasing 2% every year. Up to now, the electricity to the city was supplied by two three-phase circuits connecting different stations and substations. These circuits were built up between 1978 and 1986 and composed of 380 kV low pressure, oil-filled cables having 1200 mm² copper conductor and corrugated aluminum sheath. Each circuit was designed to carry a continuous load of 600 MVA in normal conditions and an emergency overload of 1040 MVA by adopting a water forced cooling system. In order to afford the increased power demand, the City Authority for electricity Vienstrom started in the 90’s the planning for a new 5.2 km long double circuit (approx 32 km of single core cable) to reinforce the grid. After detailed studies, Vienstrom concluded that the best technical and economical solution for these new connections is the adoption of a 380 kV XLPE cable having a 1200 mm² copper conductor. The lines run through an urban area of the city with high population density and crowded with other services. The cable is installed directly buried in trench in flat formation together with the cooling water pipes, and the power rating will be the same as the existing cables both in normal and emergency operation. A Real Time Thermal Rating (RTTR) system for the continuous temperature and load monitoring has been provided along with a special cable design developed for reducing the interferences with the existing services. Additionally, an innovative system for the mitigation of induced electromagnetic field in proximity of the joint bays has been adopted. The project construction starts in middle 2004 and it is planned to be completed by November 2005.
  • 9:15 - 9:45 - EHV XLPE Cable Systems in Japan and Saudi Arabia
    Yoshiharu Nakamura, VISCAS Corporation
    Abstract: Two new EHV XLPE insulated cable systems are being presented. One is the 500kV XLPE cable system in Japan, installed into a new hydroelectric power station last year. This system consists of three 5,900-ft circuits without joints. And another is the 380kV XLPE cable system in Saudi Arabia, about 5.6 miles, which is under construction. Large size copper conductor strand insulated by cupric oxide film was adopted to reduce skin effect factor loss by conductor current. 42 prefabricated-type joints are being assembled. The cable system will be commissioned in June 2005.
  • 9:45 - 10:15 - 7150' Directional Drill Under the Cooper River in Charleston, SC
    Jay Williams Power Delivery Consultants and Jerry Ruschkofski, SCE&G
    Abstract: South Carolina Electric & Gas (SCE&G) successfully completed a 7150-ft directional drill under the Cooper River in Charleston, SC in the summer, 2004, and installed an 8.625-inch steel cable pipe, followed by installing 2250-kcmil, 115-kV HPGF cables. The project included installing HPGF terminations at 75+ ft. elevation on a transition pole in a manner similar to XLPE transition pole terminations. A second bore and steel pipe were installed a few months later, for potential future reinforcement of the cable supply to a rapidly growing suburban area. This presentation provides details of the project planning, directional drills, pipe installation, cable installation, and termination structure.
  • 10:15 - 10:30 - Break
  • 10:30 - 11:00 - Condition Assessment of Transmission Power Cables
    Edward Gulski, Delft University of Technology, The Netherlands: Paul P. Seitz, Seitz Instruments AG, Switzerland; Frank Petzold, SebaKMT, Germany; Lawrence Lamballais, Pirelli Cables and Systems, The Netherlands; Frank de Vries, Nuon, The Netherlands.
    Abstract: From the reliability and availability performance point of view, HV components such as power cable sections which are installed in the transmission network are very important assets. Moreover, the liberalization of electricity markets has two effects on the business environment of power utilities: - the maintenance and investment costs have to be optimally reduced using the maximum service life of the existing transmission power cable networks; - due to increasing cost of non-availability a higher reliability in power supply is requested. In this contribution, systematic experiences on condition assessment of power cables as made in the transmission network in The Netherlands are discussed. After analysis of dominant failure processes typical for a particular type of power cable, the actual insulation condition is evaluated using advanced, non-destructive, on-site techniques such as PD diagnosis methods for detecting and localizing in all types of above mentioned HV components the discharging insulation weak spots, tan- measurements, dissolved gas analysis or RVM to determine the long-term overall paper-oil and mass insulation degradation. In particular, based on criteria as developed for each component and for each diagnostic tool, all results as obtained from different diagnostics are used together for a classification of the assets into possible condition categories. Moreover, taking into account the specific type of the component as well as the operation and maintenance history, the asset condition are indexed by means of data base and data mining. As a result, integral knowledge rules are used to support the asset management decisions about maintenance and replacement policy.
  • 11:00 - 11:30 - Basics of Frequency Domain PD Testing
    Steve Boggs, University of Connecticut
    Abstract: Frequency domain PD testing has been used in a wide range of field applications, including gas-insulated substations, transmission class solid dielectric field, and distribution cable. The primary advantages are (i) the ability to work in regions of the electromagnetic spectrum which have relative little interference and (ii) the ability to detect PD without having to detect an individual PD above the background noise. Frequency domain PD detection differs from time domain detection in a number of fundamental ways which will be discussed in this presentation.
  • 11:30 - 12:00 - EPRI Projects Update

  • 9:35 - 9:55 - Circuit Integrity Cables Hydrocarbon Pool Fire Test 2000°F (1093°C), High Power
    Peter Blackford and Art Maldonado, CABLE USA, Inc.
    Abstract:  Fire Safety has become increasingly important in several industries, particularly the Petrochemical Industry, where the loss of lives and property can be devastating and very costly. Recent refinery fires in Texas, and in California, have brought attention to more stringent fire protection safeguards.
    
    One of the cable fire tests available to the industry is UL Standard 2196, “Test for Fire Resistive Cables”. As with any large-scale test, however, this protocol is both costly to perform and prone to lack of thermal uniformity.
    
    The proposed Hydrocarbon Pool / Circuit Integrity Fire Test is designed with considerable input from the Petrochemical Industry to closely mirror the hydrocarbon pool fire scenario. This protocol can be a useful tool in the development of technology to design cables that maintain circuit integrity during fire situations. These cable are normally used for critical circuits powering and monitoring Emergency Isolation Valves (EIV), and Motor Operated Valves (MOV), which are designed to limit the duration and severity of a fire.
    
    Scope of Flame Test: The intent of this protocol is to provide a rigorous yet efficient method of determining the integrity of electrical cables in a simulated refinery fire environment. Developmental data have shown outstanding repeatability of results. Further, this protocol incorporates test requirements for cable, which is installed directly in a cable tray, as well as for cable as installed in rigid conduit.
    
    The flame source is to provide a minimum heat output of 65,000 Btu/sq.ft./hour. The temperature of the flame is to be 1093° C (2000° F) minimum. The cable will be evaluated under both operating voltage and current conditions, typically 480VAC and 15A minimum.
    
    The burner equipment has been specified to use a readily available MAPP (Methylacetylene-Propadiene + Liquified Petroleum Gas) gas and air mixture. The MAPP gas, when properly mixed with air, will produce the required 1093^oC (2000^oF) flame temperature under tightly regulated conditions.
  • 9:55 - 10:15 - Effect of Focused vs. Unfocused Light Beam of 375nm on the Absorption Coefficient of Carbon Black Pigmented Linear Low Density Polyethylene
    Bob DeMair, The Okonite Company
    Abstract: The standard test method for determining the Absorption Coefficient of linear low density polyethylene material pigmented with carbon black is ASTM D 3349 - 99. This method describes how to measure the amount of light transmitted through a film of carbon black pigmented polymer. When the light transmittance and the film thickness are known a calculation for absorption coefficient can be completed. ASTM D 3349 – 99 does not give direction on where to place the sample along the light path. The sample location determines how large an area is illuminated by the light beam. The purpose of this paper is to determine if sample placement can impact absorption coefficient.

  • The New Turbigo-Rho 380 kV Transmission Line: An Example of the Use of Underground XLPE Cables in a Meshed Transmission Grid
    Abstract: The need of a 380 kV transmission line between the 1600 MW Power plant of Turbigo, near Milan, and the substations at Ospiate and Bovisio was highlighted since the ‘90s, with the primary scope to avoid congestions consequent to the high power transiting from Swiss and France and to reinforce the West-East transmission axis in the highly industrialized and populated area in the North of Italy. The project was included it in the National Development Plan in 2001 as a top priority project, key to guarantee the required reliability and availability to the transmission network, this priority becoming absolute after the 28th September 2003 black-out event. The project construction starts in early 2005 and it is planned to be completed by April 2006.

    Due to the necessity to cross a highly urbanized area and to fulfill the stringent requirements in terms of environmental impact (electric and magnetic field limitation, visual impact, etc.) an underground XLPE cable system was decided to be installed throughout the whole sensitive area. The presentation describes the Underground XLPE cable system, a double circuit 2000 mm² Cu conductor with a maximum ampacity of 1600 A/circuit, which represents the first realization of this extension and importance in Italy and also one of the most important world-wide. A full description of the XLPE cable, of the relevant accessories (joints, terminations, sheath protection devices, etc.) and of the installation is given.

    An innovative solution adopted to minimize the Electromagnetic Field (EMF) when the cable systems are laid in the most sensitive areas is also given. In order to increase safety of operation, special control devices have been foreseen for the whole cable system, in particular the continuous monitoring of the temperature through fiber optics, the remote monitoring of the fluid in the terminations and the possibility to measure the partial discharges of the joints during the system life.

  • Construction of XLPE Cable Systems with Large Conductor Size for Rated Voltage Above 345kV
    Seung-ik Jeon, LS Cable Ltd. (formerly LG Cable Ltd.)
    Abstract: The 345kV XLPE Cable system with large conductor size cable was successfully constructed in Taiwan by LS Cable Ltd. in January, 2004 and is now in commercial operation. The first shipment of cable and accessories was Sep. 2003, and the completion was Jan. 2004. Two cable lines with large conductor size (2,500 mm²) were installed and the total circuit length for each cable line is 2,400 m and 510 m, respectively. The soundness and reliability of these cable systems were tested and verified successfully, using High Frequency Partial Discharge measuring technology on site. Other experiences and future plans for constructing Ultra High Voltage XLPE cable systems for rated voltage above 345kV in domestic and international market, mostly with large conductor size, will be introduced also.
  • What is So Special About Thermal Backfills in the Middle East ?
    Deepak Parmar, Geotherm Inc.
    Abstract: It has been a practice in this part of the world to use the most commonly available "dune-sand" mixed with some cement and water and installed by compaction. On this project, the total route length is about 46 km (~30 miles) and utilizes XLPE cables operating at 66 kV, 132 kV and 220 kV, installed in either single or double circuit trenches (flat formation and tre-foil). The total volume of backfill required on the project is about 30,000 CM (~40,000 cu.yd). Specifications called for a granular type (easy to remove) corrective backfill to have thermal rho of no higher than 1.2 C-m/W in totally dry condition. No testing of thermal or mechanical parameters of this type of backfill was conducted in the past and it was assumed to have a thermal rho of 1.2 C-m/W. Design and testing conducted by a local firm could not satisfy these requirements (the rho values ranged between 1.6 to 2.8 C-m/W). A visit to local quarries to source alternate materials and conducting design/testing resulted in a choice of mixes that satisfied both requirements. The presentation highlights the differences between the thermal/mechanical performance of different types of sands and other granular materials from the region.

    Bottom line: Assumption can be very costly - with the current knowledge and technology there is no reason for excuses.

• Educational Program - A Review of Secondary Underground Cable Basics - Wednesday, April 20th, noon - 5:00 pm
  Abstract:  The topic of 600 volt underground secondary cable is seldom discussed at ICC meetings where medium and high voltage underground cables receive most attention. However, underground secondary cables form an important part of a utility system considering larger utilities install more than 1 million ft. of underground secondary cable per year and spend several million dollars annually on secondary underground cable repair costs. This Educational Program will focus on the topic of underground residential and commercial services and underground streetlight cables. Presentations from the cable manufacturers will cover the manufacture, design, materials and industry specifications covering secondary cables. Learn about the latest secondary cable design technologies and their potential benefits. Presentations from the utilities will focus on their experience with underground secondary cables and splices. The Educational Program will also feature a presentation on the results of a utility survey on secondary cables conducted specifically for the benefit of utilities attending this session. Attendees will receive 4 PD hours.

  For additional details on the presentations please refer to the abstracts listed below:

  • The Manufacture of 600 Volt Underground Secondary Cables
    Nick Ware, Southwire.
    Abstract: Manufacturing techniques for 600V utility cables have changed in the past several years. These products demand the highest quality and reliability yet are viewed as commodity products in our industry. The result is a constant pressure for improved techniques and efficiencies in manufacturing. The various techniques of manufacture and design will be discussed, as well as some newer product designs that can further improve reliability.
  • History of Ruggedized URD Cable Development
    Kyle Cope, Pirelli Cables & Systems NA
    Abstract: From its beginnings as a pair of copper conductors wrapped in rubber to the current use of polyethylene, the idea of URD cable has been with us since the 1800s. Polyethylene insulated secondary URD cable has been around since the 1960s and has seen some design and process (manufacturing) changes over the years. Current technology, the concept of "ruggedizing" cable, has greatly improved the performance over basic polyethylene insulated secondary URD, but has been in use since the mid 1970s. The next advancement in the development of this design is here - Secondary URD cable that will actually heal itself if damaged.
  • Industry Standards for 600 volt Underground Secondary Cable,
    Bruce F. Vaughn, Alcan Cable
    Abstract: Cable manufacturers utilize industry standards, and utility customer specifications for the manufacture of 600 volt underground cables.

Material, testing, and qualification requirements will be included
  • Overview of Polyethylene Used for 600 volt Underground Secondary Cable
    Paul Caronia, Dow Chemical Company.
    Abstract This presentation will be an overview of the polyethylene materials used in 600 volt underground secondary cable. We will provide a review of the types of polyethylene used, the key material parameters and the advantages/disadvantages of the different grades of polyethylene used in today’s 600 volt cables. Additionally, we will discuss the peroxide and moisture crosslinking processes used to produce these cables, and why each is used, along with an overview of the new developments in moisture cure technology.
  • Failure Rate of Bare Concentric Neutral 600-Volt Cable
    Neal Parker, Puget Sound Energy
    Abstract: In the mid-1960s Puget Power installed a 600-volt cable that was made of two insulated phase conductors and a bare tinned-copper concentric neutral. The construction was called “flat twin” or “ribbon” cable. Neal Parker will present the results of his investigation into this cable’s performance. The almost total lack of reliable data resulted in unique investigative techniques to estimate the number of these cables and how many fail each year. From this information and anecdotal evidence, the failure rate was estimated and a corporate approach is recommended.
  • How Reliable are your Underground Secondary Circuits?
    Timothy J. McLaughlin, Public Service Electric & Gas (PSE&G).
    Abstract: There has been much interest of late in the growing problem of secondary connection failures. Fortunately, there are a few solutions to this nagging industry problem. PSE&G methodically tracks its underground primary failures. We know when they failed, why they failed and how our customers were affected. With secondary failures we are far less diligent. The reason for this at PSE&G as well as other utilities is that secondary failures are viewed as a small problem. They have almost no impact on your reliability numbers as only one customer is usually out at a time. They are low-cost when compared to primary failures, and they are usually easy to repair. The problem comes in when you add all of these failure totals up and see how they impact the bottom line. This presentation will focus on the sources of these failures and the way PSE&G has attempted to fix them.
  • Secondary Cable Failure Statistics at TXU Electric Delivery Company
    Richie Harp, TXU Electric Delivery
    Abstract: The TXU Electric Delivery underground system consists of about 19,000 miles of cable. This is divided into 13,000 miles of medium voltage cable and almost 6,000 miles of low voltage secondary cable. Most of the attention for cable failures is on the medium voltage cable, but there are a significant number of secondary cable failures that can be almost as costly as the medium voltage cable failures. This presentation will address the secondary cable system, the failures experienced on this system and the cost of these failures.
  • The History of Secondary Cable Designs at Commonwealth Edison Company
    John Hans, Commonwealth Edison Company
    Abstract: Commonwealth Edison has approximately 27,000 conductor miles of 600-volt class cables on the system. Ruggedized cables have been used for residential applications for the last 25 years. The presentation will review the historical usage of 600-volt cables and their respective performances.
  • ICC Educational Program Secondary Underground Cable Survey
    Steve Szaniszlo, Power Cable Consultant
    Abstract: The results of a survey conducted specifically for this ICC Educational Program on 600 volt underground secondary cables used for residential and commercial services and underground streetlight cables will be reviewed. This survey explores 600 volt underground secondary cable usage, designs and splices used, cable failure rates and solutions evaluated to mitigate cable failures by the contributing utilities.
