  • SF6 End-of-life Vacuum

    SF6 End-of-life Vacuum. Sulfur hexafluoride (SF6) is one of the most stable gaseous chemical compounds due to its inertness (Its inertia is comparable with nitrogen (N2) gas) and incombustible nature. It has been more than 6 decades since SF6 is being used in electrical equipment.

    2020-10-23Due 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
