Siemens supplies green 66kV switchgear for UK wind farm· Siemens will supply 102 high voltage gas insulated switchgear (GIS) for a UK wind farm in a multi-million euro deal. The switches operate with a vacuum circuit-breaker and clean air instead of polluting sulfur hexafluoride (SF6) as the insulating medium.
SF6 Switchgears - ELECTRONSYSTEM MD is a gas used by switchgear manufacturers in making their equipment because of its unique dielectric and breaking properties. The main use of the gas, although it is used in multiple other industries, is in high and medium voltage switchgears.. When it comes to medium voltage (MV) switchgears, SF6 is the single proposed solution that suits the switchgear.
High Voltage Switchgear SF6 Maintenance the years, installations have started to show signs of SF6 breakdown, decomposition and leakage. Given the fact that SF6 is also a potent greenhouse gas, 22,000 times more dangerous to the ozone layer than CO2, power companies are now required by law in the European Union, under the Kyoto Protocol, to monitor vessel top-off and leakage.
