  • 2:30 - 3:05 PM - "Where does the 3.5 come from?" George Anders, Aco-Anders Consulting Ltd., Detlef Wald, Eifelkabel
    In the IEC 60287 the thermal conductivity of the XLPE insulation has been assigned the value of 3.5 K*m/W. When computing the insulation thermal resistance, a key component of cable current rating, the semi-conducting material is assigned the same value of the thermal conductivity.  Both values are constant over the whole temperature range. One must say that this statement is quite optimistic, since firstly the semi-conducting material are completely different from the insulation and secondly both materials change the morphology between 23 ºC and 130 ºC and, thus, also their thermal conductivity. There are different methods how to measure the thermal conductivity of materials. We focused on a certain series of measurements and evaluated the impact of these different results on the ampacity

  • 4:10 – 4:50 PM - “Advances in Elastomer Technology for Cable Applications” Paul Brigandi,Paul Caronia, Juan Tuberquia, Greg Li, The Dow Chemical Company
    Traditional ethylene based elastomers such as ethylene propylene rubber (EPR) and ethylene propylene diene (EPDM) have an accepted structure for use in many cable applications.  Advancements in molecular catalysts and production technology make possible the precise control of molecular architecture that enables a broader diversity of polymer structures that can provide unique performance compared to the traditional EPR and EPDM polymers.  As a result of these developments, elastomers with differentiated performance such as higher temperature and loading capabilities are available to achieve improved cable performance.

  • 4:50 – 5:30 PM - “ICEA Standard S-97-682-97 Hyperbaric Accelerated Water Treeing Test (AWTT) Performed at 1, 250 and 310 bar” John T. Smith, III (1), Daniel Isus (2), Michael D. Alford (3), Masoud Hajiaghajani (4), John T. Whiddon (5) 1 - General Cable Corp, Scottsville, TX, 75688 (USA) 2 - Grupo General Cable Sistemas, S.A. GCC Manlleu, Spain 3 - Chevron Energy Technology Company, Houston, TX, 77002 (USA) 4 - Chevron Energy Technology Company, Houston, TX, 77002 (USA) 5 - Aker Solutions, Mobile, AL 36605, (USA)
    The Accelerated Water Treeing Test (AWTT) of ICEA standard S-97-682-97 has been performed on tree-retardant crosslinked polyethylene (TRXLPE) insulated cables having blocked and unblocked conductor strands, at 1 (ambient), 250 and 310 bar hydrostatic water pressure for up to 450 days. Minimum residual dielectric AC breakdown strength requirements of the ICEA standard after AWTT via a step-rise high voltage time test (HVTT) at 120, 180 and 360 days were met at all three (3) test pressures, and were statistically equivalent at all test pressures. Degradation rates of AC breakdown strength were also identical at all test pressures. The number of bow-tie trees observed at or near HVTT failure sites as a result of AWTT being performed at 250 and 310 bars were higher than at ambient pressure (1 bar). The bow-tie tree density (#/.in3) growth rates at 250 and 310 bar are also greater than at 1 bar.  Vented treeing (either at the conductor shield or insulation shield interfaces) at 250 and 310 bar was essentially non-existent. AWTT performed at 250 bar for 270 days, followed by an additional 180 days at 310 bar, also showed equivalency (with regard to levels and degradation rates for breakdown strength and treeing) results at 1 and 310 bar testing.  These test results indicate that this TRXLPE insulation system can be expected to operate reliably at its intended operating voltage in sea water depths of up to 10,000 feet for its projected 40-year life.

  • 3:45 - 4:00 Break  
  • 4:00 - 4:45 PM   1000 V Cable with Cracked EPR Insulation , Bogdan Fryszczyn - Cable Technologies Laboratory
    Abstract - The average age of the U.S nuclear power plant, since commissioning, is 34 years.  The cables in the plant are even older than that, as the cables are put in operation few years before the plant is commissioned.  A deteriorated condition of the indoor, low voltage cables, insulated with black EPR and covered by Neoprene jacket (not bonded to the underlying insulation) will be described.  The cables were removed from service because of their very low insulation resistance obtained during routine in plant maintenance testing.  It will be shown that the thermal degradation of Neoprene jacket is responsible for:  
    1) Cracking of EPR insulation 
    2) Low insulation resistance values
    Bogdan Fryszczyn earned his Master’s degree and PhD in Physics from the Warsaw University in Poland.  He is employed by Cable Technology Laboratories, founded by Dr. George Bahder, almost from the CTL inception.  Over the last few years a considerable amount of his time has been devoted to the investigation of the aging and failure mechanism of low and medium voltage cables and cable accessories installed in the U.S. nuclear power plants.
  • 4:45 - 5:30 PM - Impact of Char Integrity on Flame Retardant Performance of Low Smoke Zero Halogen Compounds, Yimsan Gau, Cable Consulting Services, Rodney Ginger, Cable consultant
    Abstract - Low smoke zero halogen (LS0H) compounds reduce the fire risk and minimize fire hazards. In conventional LS0H technology, this is achieved through the use of metal hydrates which can be either aluminum tri-hydrate (ATH) or magnesium hydroxide, MDH. They act as heat sink through the endothermic decomposition, release water above the decomposition temperature and then leave a residue in the form of a char after combustion. The char acts as a physical and thermal barrier for the underlying material. The physical barrier reduces the rate of release of volatile combustible gases feeding the flame. Thus the integrity of the charred layer is instrumental in achieving good flame retardant performance  
    The loading of ATH or MDH can range from 60 to 70% to meet the relevant flame performance. This generally leads to both poor processability and physical properties of the compounds and cables. Thus, several approaches have been sought to lower the loading of metal hydrates while improving all the relevant properties including the flame retardant (FR) performance. The most common one is to take advantages of the synergistic factors mainly through the formation of a more robust char by evaluating potential synergistic fillers in the metal hydrate systems in order to reduce as much as possible their loading.  
    The paper gives a review on the improvement in FR performance of LS0H compounds specifically formulated with MDH through addition of nanoclay to meet the high FR performance such as VW-1 flame rating. Most of the reported synergy of MDH/nanoclay is based on cone calorimeter data. Additional work is needed to confirm the benefit of nanoclay at the higher MDH loadings of 60-70% to meet the VW-1 applications. The impact of the integrity of the charred layer of MDH on the synergy of MDH/nanoclay is discussed. An overview of the FR performance of other FR systems such as, addition of metal oxides, and calcium carbonate to MDH, and blending of ATH/MDH is also covered.

  • 9:35 AM -  10:20 AM: “Evolution of Dielectric Loss Diagnostic Features for Miniature Cables with PE Insulation through Various Stages of Degradation”,  Jean-Francois Drapeau and Simon Bernier, IREQ (Hydro-Quebec Research Institute), CANADA
    This presentation will show the results of a study aimed to investigate the relation of dielectric loss diagnostic features with the aging condition of miniature cables with PE based insulation. It is actually a sequel of the previous presentation that was made at ICC S2014 Sub F meeting relating to the same study. At that time, the focus was placed on VLF Tan delta. The purpose of this presentation is to present a more complete figure of the evolution of diagnostic features associated with dielectric loss measurements, including this time the results from Time Domain Spectroscopy (TDS). As a reminder, the cables used for this study were miniature cables (RG-58) having an insulation thickness of ~1 mm. The aging took place by having them immersed in tap water and energized at 5 kV AC up to ~18000 h. Dielectric loss diagnostic tests were performed at various time intervals (from 1000 h to 2000 h) using a VLF sine wave @ 0.1 Hz and the time domain spectrometer developed at IREQ. The presentation will introduce several new diagnostic parameters that could eventually be used to improve the accuracy and informative value of diagnostic assessment based on dielectric loss.    
  • 10:30 AM – 11:00 AM:  “Preliminary on-site classification of MV cables by using a simple DC insulation tester”, Sverre Hvidsten, Sintif – NORWAY.
    Condition assessment of water treeing in medium voltage XLPE cable insulations by tan δ measurements is well established. However, the interpretation of the measurements can be difficult and even wrong if the cable section has one or more joints with a low insulation resistance, as the tan δ can be significantly higher for the joints than for the cable insulation. This presentation describes a simple method based on using an insulation tester to reveal if joints with low resistance are present in the cable link. Measurements have been performed on cable samples with joints taken from service after more than 20 years due to high tan δ values and partial discharges located in the cable. The joints were characterized in the laboratory by time domain dielectric response and dielectric spectroscopy. It has been shown that both the polarization and depolarization currents should be used during the assessment to provide robust evaluation criteria to distinguish the response of a low resistance joint from heavily water treed cable insulations avoiding misinterpretation of the cable condition. This method should be used before applying any other diagnostic equipment for such cables. In addition, the reproducibility of the measured currents has been evaluated by performing on-site measurements on different cable sections with actual joints. It is shown that both the polarization and depolarization currents remain approximately unchanged, indicating that robust criteria for cable condition assessment can be established. Finally, the cause for the high polarization currents (or low resistivity) of the joints is likely the combined action of water sorption and thermal ageing of the stress control sleeve.
