sulphur hexafluoride Grid Solutions for HV MV

However, a solution was needed that could replace the switching, extinguishing, and insulating gas sulfur hexafluoride (SF₆) that has been used worldwide for decades. The gas's chemical and electrical properties are ideal for use in compact switchgear, but SF₆ has high global warming potential, which is why an alternative had to be found.
