ABSTRACT OF THE DISCLOSURE A compressed gas-insulated bus between a metal- enclosed, compressed gas-insulated high-voltage switching installation and a transformer. The compressed gas-insulated bus, with or without a compensator, serves to connect a transformer to a metal-enclosed, compressed gas-insulated high-voltage switching installation. Since the transformer must sometimes be replaced, the gas-insulated bus should provide an as large as possible, compensable tolerance zone for the position of the transformer connection. For this purpose, the transformer connection to the gas-insulated bus with a compensator is connected by means of a first rotary flange to one end of a Z- or U-shaped enclosed compressed gas-insulated bus connection member, the other end of the connection member being connected to the gas-insulated bus proper by means of a second rotary flange. The compensable tolerance zone is determined by twisting this gas-insulated bus connection member and by the allowable angular movement of the compensator, whereby the allowable axial movement of the compensator can be disregarded. In a gas-insulated bus without a compensator, the transformer connection and the gas-insulated bus are each connected via respective rotary flanges to respective Z-shaped gas-insulated bus connection members with each connection member being connected to the other via further rotary flanges. Such a gas-insulated bus is disposed between a transformer and a compressed gas-insulated high-voltage switching installation of an electric supply plant.
