Abstract

Provided is a gas insulated switchgear the insulation performance and insulation reliability of which are enhanced and also provided is a gas insulated bus bar for the gas insulated switchgear. The gas insulated switchgear has a high voltage conductor (1) supported by a support body (3) in a hermetic container (2) into which an insulation gas (4) is sealed. An electric field relaxation shield (5) made of an insulator is interposed between the support body (3) and the high voltage conductor (1). A conductive layer (10) electrically connected to the high voltage conductor (1) is formed on the surface of the electric field relaxation shield (5) facing the high voltage conductor (1). Alternatively an end shield (6) made of an insulator is interposed between an electrical path end of the high voltage conductor (1) and the hermetic container (2). The conductive layer (10) electrically connected to the high voltage conductor (1) is formed on the surface of the end shield (6) facing the electrical path end.
