Abstract (en)

In a high voltage outdoor electrical bushing assembly (20) fur use, for example, as an entrance bushing on high voltage electrical equipment, such as an interrupter or the like, a portion is formed from an indoor bushing (22) adapted to be connected to a shielded electrical cable which meets the dimensional industrial standard for indoor bushings. More specifically, the high voltage outdoor electrical bushing assembly (20) may include an indoor electrical bushing formed from a resinous material, such as an epoxy, and a complementary bushing adapter (24) including a weathershed formed from an elastomeric material, which provides the additional clearance required for outdoor applications. The bushing adapter (24) may also provide electrical stress relief at the elastomer to air interface and the elastomer to epoxy interface. Because of the standardization of the bushing (22) used for both indoor and outdoor applications, the cost of manufacturing outdoor bushings can be substantially reduced. <IMAGE>
