    Oct 15, 2020Less visible but just as important are switchgear devices that protect electrical equipment. But did you know that many of these devices—widely used in electric-utility transmission and distribution systems as well as commercial and industrial facilities—integrate the most powerful greenhouse gas, sulfur hexafluoride (SF 6)? Luckily, leakage rates are low and accidents extremely rare.

  • 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.
