SF6 Circuit Breaker: What Are They? (Types and Operation ...· Due 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.[email protected]

What is Oil Circuit Breaker? - Operating Principle ... gas, thus liberated surrounds the arc and its explosive growth around it displace the oil violently. The arc is extinguished when the distance between the fixed and moving contact reaches a certain critical value, depends on the arc current and recovery voltage. The oil circuit breaker is very reliable in operation, and it is very cheap.
