Claims
- 1. A process for producing a crosslinked polyethylene insulated cable having an outer semiconductive layer which comprises providing an internal semiconductive layer, and an electrically insulating layer on an electrical conductor in conventional manner, coating by extrusion a resin composition comprising 100 parts by weight of an ethylene/vinyl acetate copolymer having a vinyl acetate content of at least about 55% by weight and about 5 to about 100 parts by weight of carbon black and a crosslinking effective amount of a crosslinking agent on said electrically insulating layer and heating said coated composition to at least about 250.degree. C. in a nitrogen atmosphere to crosslink said resin composition.
- 2. The process of claim 1, wherein said ethylene/vinyl acetate copolymer has a vinyl content of at least about 80% by weight.
- 3. A crosslinked polyethylene insulated cable produced by the process of claim 1.
- 4. A crosslinked polyethylene insulated cable produced by the process of claim 2.
- 5. The process of claim 1, wherein from about 0.3 to about 2 wt% of said crosslinking agent is present, based on the weight of the resin.
- 6. The process of claim 1, wherein said crosslinking is conducted at a temperature up to 290.degree. C.
- 7. The process of claim 1, wherein said temperature is at least 270.degree. C.
- 8. The process of claim 7, wherein said temperature is up to 290.degree. C.
