  • SF6 Circuit Breaker: What Are They? (Types and Operation

    Oct 23, 2020An 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. 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.

Their capacitance is fairly independent of the voltage level, ambient temperature, proximity effects and place of installation. However, the most appreciated property of compressed-gas capacitors is their extremely small loss factor.
