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. The transformers will be among the most powerful in the world, meeting the most stringent performance, reliability and safety standards. Each transformer weighs 800 tons, measuring 32 meters in length. ABB's state-of-the-art 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."
