The key difference between g3 and insulating gas 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.

Gas-Insulated Substations - GIS

sf6 gas is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the insulating gas will not condense into a liquid at the lowest temperatures the equipment experiences. Sulfr hexafluoride has two to three times the insulating ability of air at the same pressure. Sulfr hexafluoride is about 100 times better than air for interrupting arcs.
