SF6 decomposition solutions GE

The key difference between g3 and SF6 is that g3 is a gas mixture while 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.
