Name of the Project
Dianxibei-Guangdong ultrahigh-voltage direct current (UHVDC) transmission link.

Location
The project is located in south-western China.

Client
China Southern Power Grid Company.

Project Description
The Dianxibei-Guangdong UHVDC transmission link is expected to transmit 5 000 MW of power over 1 950 km.

The link will transmit clean hydropower from Yunnan province 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 has the capacity to meet the yearly power consumption needs of more than ten-million people based on average per capita national consumption. It will also help the region to significantly reduce coal consumption and mitigate carbon dioxide and sulphur dioxide emissions.

Latest Developments
ABB has won an order worth more than $40-million to provide advanced power equipment for the 800 kV Dianxibei-Guangdong UHVDC transmission link.

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 2 400 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 direct current capacitors, as well as equipment for converter valve towers and halls.
