Thermoluminescence in XLPE cable insulation

IEEE Transactions on Dielectrics and Electrical Insulation, 1996
Crosslinked 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.

Electroluminescence in water-treed XLPE

Proceedings of the 2004 IEEE International Conference on Solid Dielectrics, 2004. ICSD 2004., 2004
Electroluminescence (EL) occurs in initiation phase of electrical tree and is considered to be a probe of the degradation of polymer insulating materials. On the other hand, under existence of water, water treeing takes place when subjected to a high electric field.

Leakage current characteristics of XLPE

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1981, 1981
Because 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 ...

Voltage life characteristics of XLPE

Proceedings of the Twenty-First Symposium on Electrical Insulating Materials, 2005
Voltage 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.

Design of XLPE cables and soundness confirmation methods to extra high voltage XLPE cables

IEEE/PES Transmission and Distribution Conference and Exhibition, 2003
The design of XLPE cables, degradation factors to working XLPE cables, and exclusion methods of the degradation factors are reviewed. In addition, the soundness confirmation methods of extra high voltage XLPE cables are reviewed. As degradation factors of XLPE cables, electric stress degradation, partial discharge degradation, and water treeing ...

A contribution to the study of aging of XLPE insulated cables

IEEE Transactions on Power Delivery, 1991
The electrical, thermal, and multiple-stress (thermal and electrical) aging of cross-linked polyethylene (XLPE) cable models has been investigated in order to get information on aging effects and mechanisms. After endurance tests, XLPE cable models have been subjected to chemical, physical, electrical, and microstructural characterization.

Accelerated aging of cross-linked polyethylene (XLPE and TR XLPE) cable insulations in wet conditions

1998 Annual Report Conference on Electrical Insulation and Dielectric Phenomena (Cat. No.98CH36257), 2002
The effects of wet service conditions and accelerated aging of cables on the density of insulations and their electrical characteristics (breakdown voltage-AC BDV) have been studied. The accelerated aging of crosslinked polyethylene cable insulations: steam and dry cured with water tree retardant crosslinked polyethylene (TR-XLPE) and without water ...

Electrical aging performance of tree-retardant XLPE versus standard XLPE as insulation for distribution cables

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 ...
