Abstract
An improved protective cover adapted to be suspended on an energized electrical conductor or insulator to protect workmen in the vicinity of the conductor. In one embodiment, the cover is an elongated tubular-shaped member formed by concentrically arranged inner and outer housings maintained in a spaced relationship by a plurality of spacers which provide and maintain an insulating air gap therebetween. A central sleeve is concentrically mounted within the inner housing and together with portions of the inner and outer housings forms a spiral passageway for suspending the cover on a conductor by engagement of the conductor with an inner concave surface of the central sleeve. The inner concave surface of the central sleeve is covered with a conductive material which reduces the strength of the electrical field stress surrounding the energized conductor. The longitudinal sides of the central sleeve are a pair of spaced vertical walls which position the conductor therebetween for suspension engagement with the concave surface of the sleeve. The housings and sleeve have a common longitudinal axis and are formed of a relatively stiff dielectric material. In another embodiment, the cover is formed by a pair of spaced inverted U-shaped dielectric members with the conductive material being provided on an inner concave surface of the inner member.
