A compressed-gas-insulated high-voltage switch installation comprises a casing enclosing the conductor carrying the high voltage, and a compressed-gas-insulated outdoor bushing, for connection to an overhead line, in the wall of the housing enclosing the switch installation. The conductor is made hollow in the outdoor bushing, and in at least a part of the casing in the housing, for the purpose of carrying a flow of gas. In the vicinity of the free end of the outdoor bushing on the one hand, and in an adjacent section of the casing, divided off by a gas-tight supporting insulator on the other hand, the conductor comprises passages for the flow of gas, the said flow of gas being set in motion by a circulating device connected to the gas chamber divided off by the said supporting insulator. |
