A gas-insulated switchgear (GIS), which conducts current and cuts off fault currents, includes a conducting wire constituting a current conducting path of a system inside a tank filled with insulating gas.

이러한 가스절연 개폐장치는 탱크와 탱크가 연결되는 경우 각각의 탱크의 내부에 구비된 도선도 서로 전기적으로 연결되어야 한다. In such a gas insulated switchgear, when the tank and the tank are connected, the conductors provided inside each tank should also be electrically connected to each other.
