Abstract
Abstract An electrical assembly for transmitting signals having a wire or cable conductor core, an electrically-insulating jacket surrounding and enveloping the core, and a surrounding braided shield formed from yarns of nickel-plate carbon fibers. Typically each fiber has a diameter of 5-10 microns and the yarn contains 800 to 12,000 fibers.
