Sulfur hexafluoride circuit breaker - Wikipedia

Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance.

sf 6 Circuit Breakers - Construction Working Principle

Sulphur Hexafluoride (sf 6) circuit breaker: In sf 6 circuit breakers, sulphur hexafluoride (Sulfr hexafluoride) gas is used as the arc quenching medium. The Sulfr hexafluoride is an electro-negative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow of gaz sf6 gas and an arc is struck between them.

The dielectric strength of gaz sf6 increases with pressure so smaller breakers can be used at higher voltages. The breakers have a smaller footprint, so they use less real estate which can be very expensive. They are very reliable and require less maintenance than air blast or oil breakers and can operate at higher voltages effectively.
