World’s first 1100 kV UHVDC transformer passes stringent tests

ABB writes next chapter in electrical history as transformers and key equipment for world’s first 1,100 kilovolt (kV) project in China pass stringent tests.

When fully operational this UHVDC link will be capable of transporting 12,000 megawatts of electricity over a distance of 3,000 km from the Xinjiang region in the Northwest, to Anhui province in eastern China. This vast amount of electricity is equivalent to twice the average annual power consumption of Switzerland.
