ABB bolsters Chinese grid
800kV link will bring hydro power to Guangdong region from Yunnan
ABB has won a $40m order to provide power equipment to the 800kV Dianxibei-Guangdong transmission link, which will bring hydro electricity from Yunnan province in southwestern China to the Pearl River Delta region.
The ultra-high-voltage direct current project is operated by China Southern Power Grid Company and is expected to transmit 5GW of power across more than 1950km.
ABB technologies will be deployed at the Xinsong converter station in Yunnan and the Dongfang station in Guangdong.
The Xinsong station is at an altitude of 2400 metres and so the valves have been specially designed to meet the demanding electrical and mechanical needs of the harsh environment, ABB said.
The Swiss company will also supply dead-tank breakers, live-tank breakers and DC capacitors, as well as equipment for converter valve towers and halls.
ABB power grids division president Claudio Facchin said: “Ultra-high-voltage technologies are a key element of our next level strategy and will help expansive countries like China to reliably and efficiently transport increasing amounts of clean, renewable power over greater distances.”
