Shielded and jacketed cables with a jacket of FEP/polyimide tape, incorporating MIL-DTL-81381/7 or /8 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 copper conductors.
