  • gaz sf6 Circuit Breakers - Electrical Engineering Info

    Sulphur Hexafluoride (gaz sf6) circuit breaker: In insulating gas circuit breakers, sulphur hexafluoride (sf6 gas) gas is used as the arc quenching medium. The sf6 gas 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 Sulfr hexafluoride gas and an arc is struck between them.
