    Mar 31, 2020SF 6 is a colourless, odourless, non-toxic gas which is five times denser than air. It has been increasingly deployed in circuit breakers and switchgear in a global array of power stations, wind turbines and electrical sub-stations, to quench arcs and stop short circuits. Often, it replaced oil-filled circuit breakers which contained harmful PCBs.

    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.
