Polarization behaviour of cross-linked polyethylene (XLPE)

10th International Symposium on Electrets (ISE 10). Proceedings (Cat. No.99 CH36256), 2003
Cross-linked polyethylene (XLPE) has low dieletric permittivity, loss factor, good dimensional stability and solvent resistance. Because of these inherent and desirable properties XLPE cables are extensively used in power distribution applications.

Polarization phenomena in cross-linked polyethylene (XLPE) containing water-trees

Conference on Electrical Insulation and Dielectric Phenomena, 2003
The authors report preliminary results of a polarization study using thermally stimulated discharge current (TSDC) measurements and the thermal current transient technique on XLPE (cross-linked polyethylene) samples in which water trees have been grown.

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 ...

Water ingress in high-voltage cross-linked polyethylene (XLPE) cable terminations

IEEE Electrical Insulation Magazine, 2012
In Norway, there are 6000 to 7000 oil-filled high-voltage cable terminations in the transmission network, most of which are constructed following the old design shown in Figure 1. Although the number of reported failures of medium-voltage cross-linked polyethylene (XLPE) cables and cable accessories is low, during the last few decades some severe ...

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.
