ON ACTION MECHANISMS AND APPLICATION RANGES OF VOLTAGE STABILIZERS
电压稳定剂作用机理及应用范围

In this paper, three kinds of voltage Stabilizers are chosen out from additives used in plastics industry and the mechanisms and application ranges of these stabilizers are investigatedby experiments, lt is shawn ty test results that they can be classify into two types according to theiraction mechanisms: one is bo radical capturer, which can inhibit electrical treeing in non-uniform field and electrical aging in uniform field, but it has almost no effect in cross-linked polyethylene; the other is weak electrolyte, which can only inhibit electrical treeing both in polyethylene and cross-linkingpolyethylene.
