Sulfr hexafluoride CIRCUIT BREAKER - ELECTRICAL ENCYCLOPEDIA

Sulfr hexafluoride means Sulphur Hexaflouride gas. It is an electro-negative gas which means that it has a strong tendency to absorb free electrons. due to this property of insulating gas gas, it is used in circuit breakers as the arc quenching medium. The contacts of the breaker are opened in a high pressure flow of Sulfr hexafluoride gas. The conducting free electrons present in the arc are rapidly captured by the gas and due to this loss of conducting electrons in the arc , arc gets extinguished.
