Siemens develops sf 6-free gas-insulated medium-voltage

Switches and switchgear that use insulating gas as the insulating, switching, and extinguishing gas remain an important part of the Siemens portfolio. At this yearHannover Messe, Siemens will present another medium-voltage switchgear that doesn't require sulfur hexafluoride (sf 6) 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.Get price
