Cross-linked polyethylene (XLPE) is a main kind of insulation materials, used in medium and high voltage power cable. High voltage XLPE cable production mainly adopts peroxide crosslinking method, and the performance of XLPE cable will be affected by decomposing by-products of crosslinking agent (DCP, dicumyl peroxide).In this paper, the XLPE cable was

Conference Record of the 1996 IEEE International Symposium on Electrical Insulation, 2002
This paper presents the results of a continuing investigation into degradation of the crosslinked polyethylene (XLPE) power cable insulation. The paper deals with the changing of water absorption of various types of XLPE power cable insulations: steam and nitrogen-dry cured crosslinked polyethylene; (XL) and steam and nitrogen-dry cured water tree ...

Electroluminescence properties and degradation of XLPE
2007 Annual Report - Conference on Electrical Insulation and Dielectric Phenomena, 2007Electroluminescence (EL), faint light observed at electric field concentrating points is well accepted as a precursor of the electrical tree initiation. EL is considered to be related to material degradation; the start of EL is the start of the degradation.

Water measurements in XLPE cables
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1985, 1985The water content in buried high-voltage cables is of great industrial interest, especially in view of the treeing observed in crosslinked polyethylene (XLPE) cables in the presence of water (1–3). It is not yet clear, however, if a minimum water content exists above which tree growth is initiated. Although the saturated-water content of PE is about 10–

Conference Record of the 1996 IEEE International Symposium on Electrical Insulation, 2002
An extensive investigation of the long term wet ageing performance of MV-XLPE power cables was started by Nordic (Norway, Sweden, Denmark and Finland) utilities and cable manufacturers in 1990. Representatives from the manufacturers and utilities were members of the project Steering Committee. The investigations were performed by the Norwegian Electric

Electrical conduction of a XLPE nanocomposite
Journal of the Korean Physical Society, 2014The resistivity, breakdown strength, and formation of space charges are very important factors for insulation design of HVDC cable. It is known that a nano-sized metal-oxide inorganic filler reduces the formation of space charges in the polymer nanocomposite.

Electroluminescence in water-treed XLPE
Proceedings of the 2004 IEEE International Conference on Solid Dielectrics, 2004. ICSD 2004., 2004Electroluminescence (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.
