High voltage bushing and method of assembling same

摘要

A high voltage bushing comprising an insulator enclosing a conductor and a mounting flange slid over the insulator. The outer surface of the insulator defines a flange seat for contacting one end of the mounting flange. A gasket may be positioned on the flange seat between the insulator and mounting flange to form a gas tight seal to prevent the escape of hydrogen. A layer of epoxy attaches the remaining portion of the mounting flange to the insulator. The insulator of the high voltage bushing is made from a composite material rather than porcelain as is traditionally used, while a high temperature asphalt material is also used.
