Project 01
Xiangjiaba - Shanghai
800kV Ultra High Voltage Direct Current Transmission Line Project
A national key engineering project and an innovative project for the development of world direct current transmission technology, it was a transmission project with high voltage levels, long transmission distances, and large capacity that had been built or was under construction at that time.
Project 02
Northwest Yunnan to Guangdong
+800kV ultra-high voltage direct current project
This project is one of the 12 key transmission channels for implementing the State Council's Action Plan for Air Pollution Prevention and Control It is also a key project of the State Council to ensure stable economic growth.
Project 03
Nuozhadu Power Station delivers electricity to Guangdong
800kV DC transmission project
The construction of the Nuozhadu Power Station's Guangdong+800kV DC transmission project is a major measure to improve the west to east power transmission capacity of the Southern Power Grid, meet the needs of Yunnan hydropower transmission and Guangdong electricity load growth.
Project 04
Changji Guquan
+1100kV ultra-high voltage direct current transmission line project
The project starts from Wucaiwan Converter Station in Zhundong, Xinjiang Autonomous Region and ends at Wannan Converter Station in Anhui Province. The aviation straight-line length is 3337 kilometers and the transmission capacity is 12000MW. The project has set a new height in the world's power grid technology. It is the world's first ± 1100kV UHV transmission DC line with high voltage level, high capacity, and long distance. In order to promote domestic interconnection, intercontinental interconnection, intercontinental interconnection, and build a global energy Internet, it has opened a new era in the development of UHV transmission technology.
