Nenvitech Sulfur Hexafluoride Vacuum

Sulfur hexafluoride is a nonflammable, colorless, odorless, tasteless, nontoxic and relatively unreactive gas which has been described quite often as an inert gas [42].The current OSHA standard for allowable maximum concentration for human exposure in air is 6000 mg/m 3 (1000 ppm) TWA [43].

  • 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.
