Claims
- 1. A conductively-jacketed electrical cable comprising from inside to outside:
- (a) two or more conductive metal center conductors each separately surrounded by an electrically insulating material;
- (b) one or more electrically conductive metal drain wires positioned parallel to said center conductors along the length of said cable outside of said insulating material;
- (c) a layer of metal-coated polymer tape coated on the side opposite the metal coating with a thin adhesive layer of semiconductive polymer film and wrapped around said center conductors, said insulating materials, and said drain wires as a unit, said tape being positioned so that its metal side is adjacent said drain wires; and
- (d) a semiconductive thermoplastic polymer protective jacket.
- 2. A cable of claim 1 wherein said insulating material comprises microporous expanded polytetrafluoroethylene.
- 3. A cable of claim 2 wherein said polymer tape is thermoplastic polyester and said metal plated thereon is aluminum.
- 4. A cable of claim 3 wherein said jacket is a thermoplastic fluoropolymer.
- 5. A cable of claim 4 wherein said semiconductive polymer film and said semiconductive polymer jacket comprise conductive carbon-filled polymer materials.
- 6. A wiring harness comprising a multiplicity of electrical cables held together as a unit along a portion of their length, each cable therein comprising:
- (a) two or more conductive metal center conductors each separately surrounded by an electrically insulating material;
- (b) one or more electrically conductive drain wires positioned parallel to said center conductors along the length of said cable outside of said insulating material;
- (c) a layer of metal-coated polymer tape coated on the side opposite the metal coating with a thin adhesive layer of semiconductive polymer film and wrapped around said center conductors, said insulating materials, and said drain wires as a unit, said tape being positioned so that its metal side is adjacent said drain wires; and
- (d) a semiconductive thermoplastic polymer protective jacket.
