Installation of Spacer Dampers Begins on Offshore Section of Haiyang Xin'an Nuclear Power Transmission UHV Project

On July 28, the installation of spacer dampers was fully initiated on the offshore section of the 1000 kV Haiyang Xin'an Nuclear Power Transmission UHV Project, marking the final critical phase of the world's first UHV project dedicated to nuclear power transmission. This project is China's first UHV project involving offshore construction. It starts from Xin'an Town, Haiyang City, Yantai, and ends at Tuanwang Town, Laiyang City, Yantai, with a total length of 80.36 km. It is constructed with double-circuit lines and a total of 161 towers. The project commenced in June 2025 and is scheduled for completion and commissioning in October 2026.
