  • sf 6 Circuit Breakers - Construction Working Principle

    Sulphur Hexafluoride (insulating gas) 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 Sulfr hexafluoride gas and an arc is struck between them.
