Baihetan-Jiangsu Project
On July 1, 2022, the Baihetan-Jiangsu ±800kV Ultra-High Voltage Direct Current (UHVDC) project of the State Grid Corporation of China was completed and put into operation.
The Baihetan-Jiangsu project is a crucial project for ensuring power supply during peak summer demand, a major project for stabilizing the economy, promoting growth and development, a green project serving the dual carbon goals, and an innovative project for achieving technological self-reliance and self-strengthening. The project starts in Butuo County, Liangshan Prefecture, Sichuan Province, and ends in Changshu City, Suzhou City, Jiangsu Province, passing through Sichuan, Chongqing, Hubei, Anhui, and Jiangsu provinces. The total length of the line is 2080 kilometers. Two new converter stations, Baihetan and Yucheng, have been built. The project has a rated voltage of ±800kV and a rated transmission capacity of 8 million kilowatts, with a total investment of 30.7 billion yuan.
In the Baihetan-Jiangsu project, our company supplied nine units of RKSGKL-480-1910-50 type and nine units of low-end RKSGKL-150-1910-50 type dry-type air-core bridge-arm reactors with technical parameters of 500kV/2250A/50mH to the Yucheng Converter Station in Jiangsu Province, totaling 18 units. All reactors have passed the type test of the China Electric Power Research Institute. The reactors bearing the "JWZN" logo will accompany the Yucheng Converter Station during peak summer demand, contributing to China's "dual carbon" action plan, promoting the development of the green economy, driving technological innovation in the power sector, and empowering a beautiful China.
