ABSTRACT:
An insulating cap for a loadbreak bushing includes an outer conductive jacket preferably having a ground wire receiving member thereon. The ground wire receiving member may be in the form of an integral tab having a bore therethrough for connection of the ground wire. The insulating cap further includes an insulation member positioned in adjacent relationship to the inner surface of the conductive jacket. In a preferred embodiment, both the inner surface of the conductive jacket and the inner exterior surface of the insulation member includes a smooth, dome-shaped region which helps to control electrical stresses, if any. The inner surface of the insulation member defines a bushing receiving space which substantially corresponds to the exterior shape of a loadbreak bushing. When properly grounded, the outer conductive jacket of the insulating cap is maintained at ground potential.
