Abstract
A hermetic lead wire having an extruded chlorosulfonated polyethylene insulation wherein the insulation also contains an acid acceptor, filler and peroxide cross-linking agent. The insulation composition and a method of preparing the insulation composition by first blending the chlorosulfonated polyethylene with the acid acceptor and then adding a filler and peroxide cross-linking agent.
Claims11
A hermetic lead wire for use in hermetically sealed electrical apparatus comprising:
- an electrical conductor having thereon an extruded layer of an electrical insulating composition having about 100 parts by weight of an chlorosulfonated polyethylene, from about 30 to about 62 parts by weight of said acid acceptor and from about 40 to about 70 parts by weight of a filler.
A hermetic lead wire for use in hermetically sealed electrical apparatus comprising:
- an electrical conductor having thereon an extruded layer of an electrical insulating composition which comprises chlorosulfonated polyethylene, an acid acceptor and a filler;
- wherein the acid acceptor is magnesium oxide and the filler is anhydrous aluminum silicate.
A hermetic lead wire for use in hermetically sealed electrical apparatus comprising:
- an electrical conductor having thereon an extruded layer of an electrical insulating composition which comprises chlorosulfonated polyethylene, an acid acceptor, a filler, a curing agent and a lubricant aid wherein the acid acceptor is magnesium oxide and the filler is anhydrous aluminum silicate.
A hermetic lead wire comprising:
- a multi-stranded metallic conductor, a polyester tape wrapped around said conductor, and a top extruded layer of a chlorosulfonated polyethylene which was extruded from a composition comprising about 100 parts by weight chlorosulfonated polyethylene, from about 30 to about 62 parts by weight magnesium oxide, from about 40 to about 70 parts by weight anhydrous aluminum silicate, from about 5 to about 10 parts by weight organic peroxide and from about 0.5 to about 1.0 parts by weight ground tetrafluoroethylene polymer.
