Siemens receives order for world's first SF6-free gas ... order includes three bays of the 8VN1 gas-insulated, SF 6-free 145 kV switchgear. This GIS uses vacuum interrupters for switching functions and treated air, known as "clean air", as the insulating medium. It is therefore possible to completely eliminate the use of sulfur hexafluoride.
