Siemens to retrofit one of the largest substations in Germany

In the future, it will thus be possible to transport large quantities of wind energy from northern Germany to the southern part of the country. Replacing sulfur hexafluoride (insulating gas) with treated air, so-called Clean Air, as the insulating medium in the bus ducts simultaneously ensures much more climate-friendly operation.Get price
