Is the end coming for sulfur hexafluoride, the most ...· Current EU F-gas regulation prohibits the use of SF 6 in many non-electric applications, but not in MV switchgear. Today, about two thirds of the 15 million MV switchgear units installed in Europe (EU28) use SF 6.When the EU F-gas regulation was last revised in 2014, it was considered that no cost-effective and reliable alternatives to SF 6 were available.

Siemens Receives Order for World's First SF6-free Gas-insula· The order includes three bays of the 8VN1 gas-insulated, SF6-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.

BPA Puts Modernized Celilo Converter Station into Service ... Pacific Direct Current Intertie, a high-voltage direct current system (HVDC), was a marvel and a model when it was energized in 1970. Direct-current systems can move large amounts of electricity over long distances more efficiently than alternating current lines of a similar length because less power is lost to the air as heat along the way.
