Sulphur Hexafluoride or gaz sf6 circuit breaker is a type of circuit breaker that uses pressurized gaz sf6 gas to extinguish the arc. It is a dielectric gas having superior insulating and arc quenching properties far better than air or oil. It is used for arc quenching in high voltage circuit breakers up to 800 kV in power stations, electrical grids
[email protected]Sulphur Hexafluoride (insulating gas) is commonly used as an insulating gas in high-voltage switchgear such as power lines, medical equipment, wind turbines and in the production of magnesium and aluminium. With a Global Warming Potential of 23,000, gaz sf6 is one of the most damaging of all greenhouse gases and stays active in the atmosphere for more than 3000 years.
