Dielectric Characteristics of XLPE and Semiconductive Materials for Power Cable

전력용 케이블의 XLPE와 반도전 재료의 유전특성

The performance of insulate materials gets worse with stress time in power system and because this causes lowering of function and accidents in equipment,development and performance improvement of excellent insulate materials are needed to make stable system. In this paper, to study the influence of degradation in XLPE, inner semiconducting layer and outer semiconducting layer, we studied dielectric characteristics at temperature 25∼100[$^{\circ}C$] and frequency 20∼ 1 [MHz]
