Leakage current characteristics of XLPE
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1981, 1981Because the leakage current in XLPE changes in proportion to the quantity of the crosslinking agent by-products, leakage current might be controlled by the amount of ion conduction carriers which are supplied with the by-products. And because the leakage current in impregnated PE sheets changes in proportion to the conductivity of each by-product in ...

Advances in TR-XLPE insulation
1999 IEEE Transmission and Distribution Conference (Cat. No. 99CH36333), 1999TR-XLPE is widely accepted within North America as the MV power cable insulation material of choice due to its superior long-life performance and excellent value. Since the introduction of TR-XLPE in 1982, evolutionary and sometimes revolutionary improvements have been made by both the compound producer and cable manufacturer leading to enhanced cable ...

Thermoluminescence in XLPE cable insulation
IEEE Transactions on Dielectrics and Electrical Insulation, 1996Crosslinked polyethylene (XLPE) has been employed in underground transmission and distribution cables because of its excellent electrical and mechanical properties, such as low permittivity and dielectric loss, high degree of toughness, and good flexibility.

Comparative Laboratory Evaluation of TR-XLPE and XLPE Cables With Super-Smooth Conductor Shields
IEEE Transactions on Power Delivery, 2004This paper provides data on four commercial tree retardant crosslinked polyethylene (TR-XLPE) and one cross-linked polyethylene (XLPE) insulated 15 kV cables supplied by three manufacturers. The cables have "super-smooth" conductor shields and "extra-clean" insulation and insulation shields.

Reduced neutral XLPE cable design
IEEE Transactions on Power Delivery, 1990The authors describe the theoretical, laboratory, and economic analyses undertaken by B.C. Hydro to determine the optimum metallic concentric neutral design for its single-conductor 750 and 500 kcmil aluminum XLPE (cross-linked polyethylene) 15 kV and 25 kV insulated concentric-neutral-type feeder cables.

Voltage life characteristics of XLPE
Proceedings of the Twenty-First Symposium on Electrical Insulating Materials, 2005Voltage life characteristics of XLPE were studied using sheet samples containing artificial impurities. To imitate cable insulation, these samples were made under almost the same condition as actual cables and the sizes of the impurities contained are near those contained in cables.

Impurities in XLPE cable resins
Proceedings of 1994 4th International Conference on Properties and Applications of Dielectric Materials (ICPADM), 2002This paper presents results on an impurity analysis of various insulation and semiconducting shield resins made by four manufacturers and used for power cables. Three different strand-blocking materials used to fill the conductor interstices were also analyzed.

IEEE Transactions on Power Delivery, 1992
The results of accelerated water treeing tests conducted on two standard cross-linked polyethylene (XLPE) and three tree-retardant XLPE compounds are presented. A correlation between miniature and full-size cable testing has been established, permitting the miniature cable evaluation technique to be used as an effective laboratory test for screening ...

Interfacial charge of XLPE/EPDM laminates
Proceedings of 1998 International Symposium on Electrical Insulating Materials. 1998 Asian International Conference on Dielectrics and Electrical Insulation. 30th Symposium on Electrical Insulating Materials (IEEE Cat. No.98TH8286), 2002Formation of space charge at the interfaces of crosslinked polyethylene (XLPE)/ethylene propylene diene terpolymer (EPDM) laminates was studied. Effects of silicone grease and some chemicals such as crosslinking coagent and coupling agent on the interfacial charge were also studied.
