Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
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.
Claim 2
Dependent Claim
113 words
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.
