News Room : GE Grid Solutions

The key difference between g3 and sf 6 is that g3 is a gas mixture while insulating gas 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.
