1. Apparatus for indicating a live voltage condition in an insulated electrical conductor consisting of a central conductor wire with insulation thereon, said apparatus comprising:

  • a layer of flexible semi-conducting tape wrapped continuously around the outer surface of the insulation;

    a flexible electrically conductive sheath wrapped continuously around the outer surface of the semi-conducting tape;

    a layer of flexible capacitive stress-relieving tape wrapped continuously around each end of the semi-conducting tape;

    an outer layer of flexible electrical insulating tape wrapped continuously around and completely covering the previously-described tape layers and the electrically conductive sheath; and

    electrical indicator means connected between said electrically conductive sheath and ground to provide an electrical signal when said central conductor wire is electrically energized.
