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.
