  • Switchgear - Wikipedia

    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.

  • SF6 Gas Hazards and How to Avoid Them - WIKA blog

    Sulfur hexafluoride (SF 6), when sealed inside power transmission and distribution (TD) equipment, insulates switchgears, circuit breakers, and disconnectors by quenching dangerous arcs. This stable and nontoxic gas, which has excellent dielectric strength, is a key component in a power plant’s safety and efficiency.
