Abstract
As LDPE, widely used as a insulating material of power cable, has defects of treeing and space charge accumulation, various methods to improve them have been suggested. It is difficult to understand the mechanism of electrical conduction according to the complexity of molecular structure and the changes of super-structure due to various environmental parameters. Therfore in this paper, four kinds of heat-treated LDPEs(origin, slow cooled, water cooled, quenched in
