  • 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.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF 6 gas is electronegative and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow of sulfur hexafluoride gas, and an arc is struck between them.
