Abstract
It has been found that the electrical conduction characteristics of polyethylene are influenced strongly by the vacuum treatment of cross-linked polyethylene (XLPE) and/or semiconductive electrodes. The major changes due to the vacuum treatment of these materials are the suppression in the rate of change of current density at some field range and the change of conduction mechanisms from the SCLC at low fields to the Schottky at high fields. These changes were attributed to the low molecular weight byproducts, which may modify the charge accumulation characteristics.Keywords
