sf6 gas Circuit Breakers - TestGuy

The dielectric strength of Sulfr hexafluoride increases with pressure so smaller breakers can be used at higher voltages. The breakers have a smaller footprint, so they use less real estate which can be very expensive. They are very reliable and require less maintenance than air blast or oil breakers and can operate at higher voltages effectively.

insulating gas Circuit Breakers - Electrical Engineering Info

Sulphur Hexafluoride (sf6 gas) circuit breaker: In gaz sf6 circuit breakers, sulphur hexafluoride (Sulfr hexafluoride) gas is used as the arc quenching medium. The sf6 gas 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 insulating gas gas and an arc is struck between them.
