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 ...

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.

The relation between voids in XLPE insulation and electrical breakdown strength of XLPE insulated cables

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1975, 1975
Electrical defects in cross-linked polyethylene insulated cables (XLPE cable) such as voids and contaminants in XLPE or characteristics of XLPE such as crystallinity and microporosity have been investigated in relation to the electrical characteristics of XLPE cable. Very small defects which can be observed with a microscope are being investigated. The

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 ...
