Bushing for gas-insulated electrical equipment.

摘要

A bushing in which a conductor (1) extends along the center of a porcelain tube (2) one end of which is closed, while its otherend is closed byacones-haped insulation spacer (11) which protrudes into the porcelain tube (2) and which also supports the conductor (1). A capacitor cone (12) is disposed to surround the conductor (1) and a predetermined portion of the insulation spacer (11) in the porcelain tube (2); an insulating material is filled into the porcelain tube (2); the side opposite to the capacitor cone (12) relative to the insulation spacer (11) is coupled to a container which is filled with an insulating gas having a predetermined pressure and which accomodates electrical equipment; and the conductor (1) is connected to the electrical equipment.
