Abstract: An electric cable with spirally wrapped wires and wire-retaining strips thereon. The cable includes an insulated electrical conductor, an extruded semiconductive insulation shield overlying the insulated electrical conductor, a plurality of strips extruded and fused onto the insulation shield, and a plurality of wires wrapped around the insulation shield and the strips with sufficient tension to partially embed them into the strips to retain them therein and resist slippage. This arrangement also permits the selection of a first material having predetermined properties for the insulation shield and a second material for the strips having different properties from the first material composing the insulation shield. In one embodiment, the material selected for the strips has a higher softening or melting point than the softening or melting point of the material selected for the insulation shield.
