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

    Oct 23, 2020Due to its low gaseous viscosity, SF6 gas can efficiently transfer heat by convection. So due to high dielectric strength and high cooling effect, SF 6 gas is approximately 100 times more effective arc quenching media than air.. Due to these unique properties of this gas, SF6 circuit breaker is used in a complete range of medium voltage and high voltage electrical power system.

  • Which is better Vacuum Circuit Breaker or SF6 Panels? - Quora

    But the vacuum circuit breakers cant be used for higher voltages.Normally, For voltages between 11kV and 33kV, SF6 is used as insulating medium and vacuum as interrupting. But for higher voltages SF6 is used for both insulating and interrupting. Moreover, it can be established in less space and hence can be preferred on some grounds. 10.1K views
