sf 6 Circuit Breaker: What Are They? (Types and Operation

Oct 23, 2020 · An Sulfr hexafluoride 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 gaz sf6 circuit breaker. SF 6 gas has excellent insulating property and it has a high electronegativity. Due to high electronegativity, it has a high affinity for absorbing free electrons.Get price
