METHOD FOR FORMING A CROSS-LINKED POLYETHYLENE INSULATOR

摘要

A cross-linked polyethylene insulation having good electrical characteristics can be obtained by laminatedly wrapping of solid phase polyethylene film containing a small amount of substantially involatile hydrocarbon insulating oil and di- alpha -cumyl peroxide round a solid article and then heating the wrapped article. The present method is suitable as a method for forming a thick cross-linked polyethylene insulation on large size conductor or forming a joint section of cross-linked polyethylene cable.
