News Detail
  • SF6 gas transfer unit - G3 - GE Grid Solutions

    Sulfur-hexafluoride (SF6) is used in the HV electrical transmission industry because it is an excellent gaseous dielectric medium. Unfortunately, it is also the greenhouse gas with the largest global warming potential (23,500 times more than C02). Much effort has been made across the industry in the last decades to find a viable alternative gas. With g³, a replacement is found in fluoronitrile versus sf6 gas.

  • News Room : GE Grid Solutions

    The results of the bus-transfer current switching tests at 1600 A/10 V showed that the mean arcing times using g3 and SF6 are almost identical for the tested slow-moving disconnector, with a slightly higher standard deviation with g3.

  • 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.
