sf 6 medium voltage switchgear advantage

Siemens has introduced another medium-voltage switchgear that doesn't require sulfur hexafluoride (SF6) as the insulating gas: the 8DAB 12.The system uses clean air consisting only of the natural constituents of ambient air as the insulating gas. The switchgear is a new addition to the 8DA and 8DB product family and also works with the proven vacuum switching technology.
