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.

Utility Reduces Risk of Explosion | T&D World solubility of the hydrogen in transformer oil is the lowest among all the gases. And, solubility of the hydrogen depends on oil temperature. The gas concentration in the headspace of the conservator varies inversely with ambient temperature. Hence, the hydrogen concentration in the bellows will be highest during the coldest period of the day.
