Sf6 Circuit Breaker In Substation. Instead of oil air or a vacuum a sulfur hexafluoride circuit breaker uses sulfur hexafluoride sf 6 gas to cool and quench the arc on opening a circuit. Sf 6 sulphur hexafluoride gas has excellent dielectric arc quenching chemical and other physical properties which have proved its superiority over other arc quenching mediums such as oil or air.

Most of air circuit breakers are use in indoor type substations. Single interruption sf6 circuit breaker is suitable for 245kv systems. An sf6 circuit breaker is a type of circuit breaker in which sulphur hexafluoride gas or sf 6 gas is used as the arc quinching medium known as an sf6 circuit breaker.
Instead of oil air or a vacuum a sulfur hexafluoride circuit breaker uses sulfur hexafluoride sf 6 gas to cool and quench the arc on opening a circuit.
Air magnetic circuit breakers are limited to older switchgear and have generally been replaced by vacuum or sf6 gas for switchgear applications. Sf6 high voltage circuit breaker sulfur hexafluoride sf6 gas is an alternative to air as an interrupting medium. Most of air circuit breakers are use in indoor type substations. Sulphur hexafluoride sf6 circuit breaker a circuit breaker in which sf 6 under pressure gas is used to extinguish the arc is called sf 6 circuit breaker.
