dilo circuit breakers SF6-alternative gases unit

SF6 Circuit Breakers - Construction, Types and Working an SF6 Circuit breaker, sulphur hexafluoride gas is used as the arc quenching medium. The sulphur hexafluoride gas (SF6) 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 and an arc is struck between them.
