Larger-than-life energy facts DC switchgear New area Old area 200 m3 4,000 m3 On converter platforms for offshore wind parks the new Siemens DC switchgear reduces space requirements up to 95 percent. Space savings 3,800 m3 This equals 50 standard ocean containers. With a size ratio of 20 : 1 the dimensional relationship is similar to that of a skyscraper with 20 floors to one floor of the same skyscraper. Compact gas-insulated highvoltage switchgear has been available for AC solutions for a few decades. But because controlling a DC electrical field is extremely tricky, it hasn’t yet been possible Find more exciting facts from the world of energy at to build compact gas-insulated systems for DC applications. Now Siemens has managed to develop an insulator that can withstand the stress induced by high-voltage DC. siemens.com/energy
