SF6-filled Insulated Equipment for HV MV

SF6-filled Insulated Equipment for HV MV

Oct 23, 2020An SF6 circuit breaker is a type of circuit breaker in which sulphur hexafluoride gas or sf6-gas 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.
