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.
Gas Insulated Switchgear - Gas Circuit Breaker Latest ... insulated switchgear assemblies are gaining importance because of the innate advantage of compactness. Inert, non-flammable SF6 provides three time stronger insulation than air; hence using it as an insulation medium allows for drastic reduction of size and space for high voltage switchgear assemblies. Our GV3 series gas

HIS - Highly Integrated Switchgear, Type 8DQ1· Sulfur hexafluoride (SF6) is used as the insulating and arc-quenching gas. All modules are attached to one another with flanges. The gas-tightness of the flange joints is ensured by the Siemens O-ring sealing principle, proven over decades of service. Gas-tight bushings permit subdividing the bay into several distinct gas compartments.
