The accumulation of space charge in cross-linked polyethylene (XLPE) under DC stress was investigated with PWP method and TSD method. The activation energy of different peaks of TSD is obtained with split multi-peak method; the polarization of dipoles and impurities is distinguished.

Mechanism of space charge formation in cross linked polyethylene (XLPE) under temperature gradient
IEEE Transactions on Dielectrics and Electrical Insulation, 2015A bipolar charge transport model is used to simulate the formation of space charge in XLPE plaques placed under a temperature gradient. The model is used to assess the relative importance of charge migration and blocked extraction for three possible effects of the temperature gradient.

Dielectric behaviours of cross-linked polyethylene (XLPE) impregnation with compressed SF/sub 6/
Proceedings of 1994 4th International Conference on Properties and Applications of Dielectric Materials (ICPADM), 2002Through comparative tests, the problem of vacuum-impregnation for a length of cable could be overcome by initial granular polyethylene being vacuum-impregnated and cable conductor being filled by compressed SF/sub 6/ after manufacture. For this purpose, the affects of pressure, temperature, voltage wave form and simulation of production process on the ...

In general, High Voltage Direct Current (HVDC) transmission is primarily used for submarine applications, including to integrate offshore wind farms to land or to transmit large electrical power over long distances across the sea. Typical insulation used within HVDC cables is either Cross-Linked Polyethylene (XLPE) or Low-Density Polyethylene (LDPE ...

This work seeks dielectric indicators of the aged state of cross-linked polyethylene (XLPE) that has been simultaneously irradiated and thermally aged. The XLPE samples studied here were of the same material formulation as XLPE insulation found in RSCC I46-0021 instrumentation cable, formed into tapes with dimensions approximately 20 × 0.7 × 100 mm3 ...

[Proceedings] 1992 Annual Report: Conference on Electrical Insulation and Dielectric Phenomena, 2003
The authors report the results of TSDC (thermally stimulated discharge current) and TTC measurements of XLPE (cross-linked polyethylene) cables AC aged in water for a period up to 4000 h. Absorption and resorption current measurements were also performed during the aging to get more information about the penetration of water and ions into the cable ...

This paper describes fundamental studies into the effects of 1) the thermal properties, and 2) the solid state structure of cross-linked polyethylene on its impulse voltage breakdown stress, as determined by the use of miniaturized cable models. Nine grades of high pressure polyethylene, clarified by molecular structure, are used in the studies.
