News Room : GE Grid Solutions

The key difference between g3 and sf6 gas is that g3 is a gas mixture while gaz sf6 is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process. To ensure this homogeneity, the filling

g3 - GE Grid Solutions

SF 6 sf6 gas (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 sf 6 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.
