GIS / Gas Insulated Switchgear

The gas insulated switchgear, referred to as GIS, uses gas rather than the air at atmospheric pressure as the insulating medium. It consists of the circuit breaker, disconnector, earthing switch, instrument transformer, lightning arrester, busbars, connectors, and outlet terminals. These devices or parts are all enclosed in a grounded metal housing, in which there are SF6 gas with excellent insulation and arc-extinguishing performance. Therefore, GIS is also called SF6 fully enclosed composite apparatus.
