Abstract

PPLP has been used as the replacement of conventional cellulose Kraft paper insulation to improve the electrical performance of power cables. High viscosity DDB oil impregnated PPLP sample has been studied in this paper. PPLP films with the same laminating processing and impregnated condition were tested at ambient temperature (20 ºC) and elevated temperature (40 ºC and 60ºC) respectively. Space charge distributions in the PPLP films under DC electric field at different temperatures were measured by the PEA technique. The results show that the charge characteristics in oil impregnated PPLP are electric field and temperature dependent. Higher temperature and higher electric field generally lead to higher charge mobility.
