What is sf 6 Circuit Breaker? Construction, Working Principle

A circuit breaker in which SF 6 under pressure gas is used to extinguish the arc is called SF 6 circuit breaker. 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. The SF 6 circuit breaker is mainly divided into three types.Get price

What is an Air Separation Unit (ASU) | Ranch Cryogenics | RCI

The remaining gases in the air are in trace amounts and normally not recovered. In very large air separation units (ASU) Neon, Xenon and Krypton are recovered in small amounts. Cryogenic air separation utilizes the differing condensing/boiling points of the components of air to enable separation by distillation at cryogenic temperatures.Get price
