Shielded and jacketed cables with a jacket of FEP/polyimide tape, incorporating MIL-DTL-81381/9 or /10 wires. These component wires have a light-weight insulation of two layers of FEP/polyimide/FEP tape with a polyimide hard coat for increased cut-through and abrasion resistance and silver- or nickel-plated high strength copper alloy conductors.
