The effect of cross-linking and cross-linking agent by-products on tree growth in polyethylene

Abstract

This paper summarizes a study of the effect of cross-linking processes and by-products of cross-linking on electrochemical tree growth in polyethylene insulated cables. The investigations dealt with cables cross-linked by radiation and chemically by peroxides. The test program also included thermoplastic polyethylene insulation containing acetophenone as an additive. Results indicate that the decomposition by-products of peroxides have a major effect on tree growth in cross-linked polyethylene insulated cables.
