EFFECTS OF SPACE CHARGE AND FRICTIONAL ELECTRIFICATION OF MIXTURE OF PE WITH EVA
聚乙烯与 EVA 共混物的空间电荷和摩擦带电效应

The relations of injection charge and frictional electrification inpolyethylene with various contents of VA were studied.The experimentsshow that the injection charges can be greatly decreased and the phenomena offrictional electrification can be eliminated with proper amount of EVA in PE.It is proved by the photoconduction spectrum that the density of deep traps inpolyethylene can be decreased by doping with EVA.A new development of ele-ctrical insulation materials of ultra-high voltage DC power plastic cable is sug-gested.
