Switchgear - Wikipedia 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.

Electrical Distribution, Protection and Controls in Mines fact, SF6 gas is known to be an electronegative gas, which means that the ability of an atom or molecule to attract and hold the electrons. It is a non-toxic, non-flammable, odorless, colourless and heavy gas, that is, the density at atmospheric temperature and pressure is five times that of air, and so it is heavier than air.

Myth About SF6 Gas In Electrical Equipment· 3. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
