However, some utilities should still set up paper-insulated lead-covered cable in distribution circuits. The conductor shield may be semiconductive (normally) or nonconducting. To drain off stray voltage, a metallic shield will be positioned over the "semicon." This shield is meant to "make secure" the cable by pulling the voltage on the surface of the insulation all the way down to zero (or a minimum of under the OSHA restrict of 50 volts).
