2009 | Record-breaker: Siemens to supply world’s most powerful 800-kV HVDC transformer to China
Following successful final acceptance tests Siemens Energy will deliver the world’s largest and most powerful 800-kilovolt converter transformer in mid-January 2010. The world-record transformer produced at the Siemens manufacturing plant in Nuremberg is destined for the Xiangjiaba-Shanghai link, a high-voltage direct-current transmission link (HVDC) recently under construction. Spanning a distance of over 2000 kilometers and with a transmission capacity of 6400 megawatts (MW), this direct-current link is currently the longest and most powerful in the world. The HVDC link, which is scheduled to come on line in 2010, will connect the hydro power plants on the Jinsha river on the upper reaches of the Yangtze in central China with the coastal megacity Shanghai. Siemens will supply ten converter transformers, five of which are rated at 800 kV, for the Fulong converter station in the vicinity of the Xiangjiaba hydro power plant.
