sf6 gas is an extremely effective electrical insulator and has significant advantages over alternative materials. It is non-flammable – a critical requirement in the high-voltage applications we use it – and because of its effectiveness takes up less volume than an equivalent insulating volume of an oil alternative.

The key difference between g3 and gaz sf6 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.
