摘要
近十余年来,电力电缆额定电压显著提高,需要能承受更高电场强度的高聚物绝缘材料,这就大大促进了聚乙烯电绝缘性能的研究工作。本文阐述了80年代初以来这个研究领域所取得的最新成果。
During the last decade,the voltage rating of power cable has increasedconsiderably, so the need for polymer to withstand high electrical stresses has become imperative. For this reason,the research on electrical insulation of PE is promoted. In this paper,the new investigative results on dielectric properties of PE at high electrical stresses since the early 80s are described.
