SF 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 SF6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.

The medium-voltage switchgear in the 8DJH family meet all requirements for safe and economical grid operation: compactness, maintenance-free design, and a high degree of operating and personal safety as well as availability. These benefits are also retained in the factory-assembled, type-tested, and 3-pole metal-enclosed 8DJH 12 model.

Oct 15, 2020Current 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.cart
