Abstract
A low-pressure gas-insulated bushing is provided including an elongated, hollow insulating shell having a terminal end and a throat end with a opening therethrough. A bushing terminal is secured to the shell terminal end, and an insulating gas at low pressure is disposed in the shell. A tubular electric conductor is disposed in the shell and extends outwardly therefrom through the throat end opening. The conductor is in electrical contact with the terminal end, thereby providing electrical connection to an overhead line. The conductor is expanded in diameter in the vicinity of the throat end to minimize the throat diameter required, while the conductor at the remainder of its length is sized to carry the rated current of the bushing.
