ABB achieves breakthrough with world´s most powerful HVDC transformer
(WorldNews Switzerland)

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 ABB has set another pioneering innovation record with the successful testing of the low and high voltage units of the world`s most powerful ultrahigh-voltage direct current (UHVDC) transformer. The +/-1,100 kV (1.1 million volts) UHVDC transformer, developed and manufactured in close collaboration with State Grid Corporation of China (SGCC), has successfully passed a series of type tests, paving the way for the implementation of the Changji-Guquan UHVDC link, which will transmit power from the Xinjiang...
