Siemens will supply 102 SF 6-free, gas-insulated 8VM1 high-voltage switchgear (GIS) to Siemens Gamesa by the middle of next year.The switchgear will protect each wind turbine individually against overloads and short-circuits and make it possible to supply electricity reliably and without interruption.
SF6 Gas Servicing Equipment – ENERVAC INTERNATIONAL ULC Hexafluoride (SF6) is an excellent gaseous dielectric for high voltage power applications. It has been used extensively in high voltage circuit breakers and other switchgear employed by the power industry. Applications for SF6 include gas insulated transmission lines and gas insulated power distribution substations.
End-of-life factors in high voltage gas insulated ...· A first indicator for end-of-life of non-SF6 gases and gas mixtures would be the gas lifetime statement of the equipment manufacturer. A gas quality check (if possible) might indicate that the equipment can be used longer, or that the gas has to be replaced if its end-of-life condition is reached.
