ABB picks up $300 million order in China

ABB has won orders worth over USD 300 million to supply breakthrough technologies for the world’s first 1,100 kilovolt (kV) ultra-high-voltage direct current (UHVDC) transmission link. The orders were booked in the second quarter of 2016.
The Changji-Guquan UHVDC link will transmit power from the Xinjiang region in the Northwest, to Anhui province in eastern China and will set a new world record in terms of voltage level, transmission capacity and distance. It will be capable of transporting 12,000 megawatts of electricity - the equivalent of 12 large power plants, a 50 % increase in transmission capacity, compared with the 800 kV UHVDC links currently in operation. This will also help extend the transmission distance from around 2,000 kilometers (km) to over 3,000 km.

ABB supplies include advanced converter transformers and components like bushings and tap changers. ABB will also supply the HVDC converter valves, DC circuit breakers, wall bushings and capacitors as well as provide system design support. Each transformer weighs 800 tons, measuring 32 meters in length. ABB’s transformer manufacturing and testing facility in Chongqing as well as the local HVDC engineering and technology center will be actively involved in the delivery and execution of the project.

“China has major load centers in its eastern region, while a significant amount of its energy resources are in the west and northwest. The expansive geography and increased demand over the last decade have prompted the build-up of UHV capacity to transmit larger amounts of power over greater distances with minimum losses,” said Claudio Facchin, President of ABB’s Power Grids division. “Ultrahigh voltage technologies are a key focus area of our Next Level strategy, and our technology advancements in this area are making it possible to increase power transmission capacity and distance to an unprecedented level with minimal transmission losses.”
