Abstract

Measurements have been made of the AC breakdown strength and the impulse breakdown strength of samples of XLPE (cross-linked polyethylene) to which known amounts of acetophenone, cumyl alcohol, alpha methyl styrene, and cumene were added. A Weibull analysis of the breakdown strengths shows that the presence of a small amount (less than 2 wt.%) of these substances has a small effect on the breakdown strength of unaged XLPE. All these substances have about the same effect: they increase the AC breakdown strength but decrease the impulse breakdown strength
