News Room : GE Grid Solutions

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