摘要
聚乙烯材料具有优良的介电性,其作为高压电缆绝缘材料的应用愈加广泛.但交联聚乙烯的导电性会随着电荷积聚以及温度梯度出现明显的变化,影响绝缘材料性能的发挥.本文综合分析了交联聚乙烯材料在高压电缆中的研究重点,希望能够为未来交联聚乙烯下料的进一步改性提供参考.
Abstract
Polyethylene material has excellent dielectric properties,so in recent years,its application as an insulating material for high-voltage cables has become more and more extensive.However,the conductivity of cross-linked polyethylene will change significantly with the accumulation of charge and temperature gradient,which will affect the performance of insulating materials.This paper comprehensively analyzes the research focus of cross-linked polyethylene materials in high-voltage cables,hoping to provide a reference for the further modification of cross-linked polyethylene blanks in the future.
