ABB has won an order worth over $40 million to provide power equipment for the 800 kV Dianxibei-Guangdong ultra-high voltage direct current (UHVDC) transmission link. The project, operated by China Southern Power Grid Company Ltd, one of the country’s two major grid operators, is
expected to transmit 5000 MW of power over a distance of more than 1,950 km.
The link will transmit hydro-power from Yunnan province in southwestern China to the Pearl River Delta region in Guangdong, one of the most densely urbanised regions in the world and a major economic and manufacturing hub of China. The link will also help the region to significantly reduce coal consumption and mitigate carbon dioxide and sulphur dioxide emissions.
ABB technologies will be deployed at the Xinsong converter station in Yunnan and the Dongfang station in Guangdong. The Xinsong converter station is located at a high altitude of 2400 m and the valves have been specially designed to meet the demanding electrical and mechanical needs of the harsh environment. ABB will also supply dead-tank breakers, live-tank breakers and DC capacitors, as well as equipment for converter valve towers and halls.
