A circuit breaker in which gaz sf6 under pressure gas is used to extinguish the arc is called Sulfr hexafluoride circuit breaker. Sulfr hexafluoride (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties and has proved its superiority over other arc quenching mediums such as oil or air. The insulating gas circuit breaker is mainly divided into three types
