Highly sensitive sulphur hexafluoride Insulated Equipment for gas-insulated switchgears

Gas-insulated switchgear or GIS is a high voltage substation in which major electrical equipment is placed in a sealed environment with sulfur hexafluoride gas (SF6) as the insulating medium. In a GIS, all the electrical switching equipment such as circuit breakers, isolators, earth switches, and busbars are completely enclosed inside modules filled with SF6 gas.

    A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
