  • 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.
