Abstract
An electrical conductor insulated with a cured heat resistant, radiation resistant, substantially dimensionally stable electrical insulation comprising a chlorinated polyethylene elastomer composition which has been electron cured with a dosage of at least 1 megarad. The product of the invention may be a single insulated wire or a group of twisted or cabled insulated wires enclosed in an electron cured chlorinated polyethylene elastomer composition jacket.
Claims9
An electrically insulated conductor comprising an electrical conductor, an inner electrically-insulating layer disposed about the electrical conductor comprising an electron-cured elastomeric composition selected from the group consisting of halosulfonated polyethylene, poly(ethylene-propylene-hexadiene)polymer, poly(ethylene-propylene-dicyclopentadiene)polymer, poly(ethylene-propylene-ethylidene-norbornene)polymer and poly(ethylene-propylene-methylene-norbornene)polymer, and an outer layer of electron-cured chlorinated polyethylene composition disposed about the said inner layer.
An electrical cable comprising at least two insulated electrical conductors and an outer protective jacket enclosing all of the conductors wherein at least one of the conductors has an inner electrically-insulating layer disposed thereabout comprising an electron-cured elastomeric composition selected from the group consisting of halosulfonated polyethylene, poly(ethylene-propylene-hexadiene)polymer, poly(ethylene-propylene-dicyclopentadiene)polymer, poly(ethylene-propylene-ethylidene-norbornene)polymer and poly(ethylene-propylene-methylene-norbornene)polymer, and an outer layer of electron-cured chlorinated polyethylene composition disposed about the said inner layer.
A cable comprising a plurality of pairs of electrical conductors insulated with the non-thermoplastic product of the electron curing of a thermoplastic elastomer and an uninsulated drain wire enclosed in a layer of aluminum or copper, a first layer of poly(alkylene terephthalate) polyester adhered to the aluminum or copper, a separate layer of poly(alkylene terephthalate) polyester disposed about the first poly(alkylene terephthalate) polyester layer, a layer of fiberglass impregnated with a silicone resin disposed about all pairs of conductors, a layer of aluminum over the impregnated layer, a layer of poly(alkylene terephthalate) polyester bonded to the aluminum layer, a second aluminum layer bonded to the polyester and a jacket enclosing the said conductors, drain wire and said layers which is the non-thermoplastic product of the electron curing of a chlorinated polyethylene elastomer composition.
