Breakdown phenomena in cross-linked polyethylene (XLPE) under high hydrostatic pressure

Proceedings., Second International Conference on Properties and Applications of Dielectric Materials, 2003
The dielectric strength of cross-linked polyethylene (XLPE) was measured under high hydrostatic pressure (50-500 bars) at temperatures of 30 degrees C, 45 degrees C, and 70 degrees C. Experimental results have shown that the breakdown field E/sub b/ decreases with temperature and increases with pressure in these ranges of values.

Polarization and charge trapping in cross-linked polyethylene (XLPE) cables AC aged in humid environment

[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 ...

Influence of SiO2 and ZrO2 Nanocomposite on the AC Breakdown Strength of Cross-linked Polyethylene (XLPE)

2021 IEEE International Conference on the Properties and Applications of Dielectric Materials (ICPADM), 2021
Evolution of high voltage (HV) cables has increased significantly over the last decade due to emerging of HVDC applications. Thus, polymer nanocomposites become one of the main research areas for exploring the potential of insulating materials in terms of dielectric strength enhancement.

Factors governing the voltage breakdown of insulating materials for cross-linked polyethylene (XLPE) insulated power cables

1980 IEEE International Conference on Electrical Insulation, 1980
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.

Influence of accelerated aging on mechanical and structural properties of cross-linked polyethylene (XLPE) insulation

Electrical Engineering (Archiv fur Elektrotechnik), 2001
This paper describes results of laboratory accelerated aging test and the influence of different aging conditions on non-electrical properties of cross-linked polyethylene insulation (XLPE). Accelerated aging has been carried out on a cable model with different electrical and thermal stresses, and with thermal stresses in air or water as surrounding ...

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), 2002
Through 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 ...

Calculation of Magnetic Fields of Cables Laid in Tunnels with Insulation of Cross-Linked Polyethylene (XLPE)

Power Technology and Engineering, 2020
The problem of ensuring the electromagnetic safety of service personnel manifests itself the most seriously in cable tunnels, where the distances between cables with high current loads and the human being is minimal. A computation technique by means of which the magnetic fields of a large number of single-phase cables may be calculated with one- and ...
