  • gaz sf6 Circuit Breakers - Construction Working Principle

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