Siemens receives order to deliver world’s first 1,100 kV HVDC transformers

Together with local partners Siemens will deliver the world’s first 1,100 kilovolt (kV) converter transformers for the world’s largest and first high-voltage direct-current (HVDC) transmission link, which has a transmission voltage of 1,100 kV DC. They are also the most powerful converter transformers in the world, with a capacity of 587.1 megavoltamperes (MVA). The HVDC link will be operated by the transmission grid operator State Grid Corporation of China (SGCC). The planned 1,100 kV HVDC transmission link between Changji and Guquan, which is currently the world’s biggest HVDC project, is 3,284 kilometers long and has a transmission capacity of twelve gigawatts (GW). ….
