  • sf 6 Circuit Breakers - Construction, Types and Working

    In an Sulfr hexafluoride Circuit breaker, sulphur hexafluoride gas is used as the arc quenching medium. The sulphur hexafluoride gas (sf6 gas) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride (sf6 gas) gas and an arc is struck between them.
