SF6 room units Siemens

Siemens develops SF6-free gas-insulated medium-voltage switchgear At this year's Hannover Messe, Siemens will present 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.
