ABSTRACT:
A metal-enclosed, gas-insulated switching installation includes at least two busbar systems and a circuit breaker. Each circuit breaker is in the form of a pole having a pole axis and at least one extinction chamber, installed in a pole housing. The pole axes are arranged perpendicularly to a foundation and are located in a first plane. The switching installation includes an electrically conductive connection, extending along a connecting axis, of the voltage-carrying extinction chamber of the circuit breaker to each of the busbar systems and an isolator arranged in the connection between the busbar and the circuit breaker pole.
