ABSTRACT:
A bushing system for high voltage electrical equipment includes a weathershed with integral annular shirts molded around an electrical conductor. The weathershed has a cavity at its base for mating with the opening in the housing for the high voltage electrical equipment. A dielectric gas in the housing communicates with the cavity in the weathershed. A flange and seal are provided at the base of the weathershed for sealingly connecting the bushing system to the housing. A secondary ground may also be provided.
