g3 - sf6 gas Free Solutions

SF 6 gaz 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 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.

The key difference between g3 and Sulfr hexafluoride is that g3 is a gas mixture while Sulfr hexafluoride 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 equipment needs to directly heat up the g3 bottle to a specific temperature, to reach the supercritical state of the gas mixture.
