Interface effect on treeing deterioration in XLPE/EX composite materials

Abstract

An experimental investigation has been carried out for evaluating the treeing deterioration characteristics of composite materials by preparing an interface between cross-linked polyethylene and epoxy resin (XLPE/EX). The results under various interface conditions are described in this paper. It is found that the interface has a great effect on the treeing breakdown pattern and on the time to breakdown under various interface conditions.
