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.
