  • Green Gas for Grid - g3 - SF6 Free Solutions

    SF 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 SF6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.What is GE’s g3?g³, (pronounced g cubed) is GEs game-changing alternative to SF6 gas, developed for HV electrical transmission equipment.Is there an alternative gas to SF6 for HV equipment?Yes, there is GE’s green gas for grids, g3 pronounced gcubed that is GEs game-changing alternative to SF6 gas, developed for HV electrical transmi...Can I replace SF6 by g3 in existing HV equipment?Direct retrofit is not possible.
