  • Sulfr hexafluoride Circuit Breakers - Construction Working Principle

    Sulphur Hexafluoride (Sulfr hexafluoride) circuit breaker: In Sulfr hexafluoride circuit breakers, sulphur hexafluoride (Sulfr hexafluoride) gas is used as the arc quenching medium. The sf 6 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.
