Patent Images
1. A shielded electric signal cable comprising from inside to outside:
- (a) a conductive metal center conductor surrounded by an electrically insulating material;
(b) at least one electrically conductive metal drain wire positioned along the length of said cable outside of said insulating material;
(c) a layer of electrically conductive shielding material positioned around said center conductor, said insulating material, and said drain wires as a unit; and
(d) at least two layers of semiconductive polymer jacketing surrounding the shielding material.
