After 225 days of construction, the 500kV Transmission Line Project, Circuit 3, Quang Trach (Quang Binh) to Pho Noi (Hung Yen) has been energized and the entire line is fully operational.

dji_0365(1).jpg — The 500kV Quang Trach - Quynh Luu transmission line project is the final component project of the 500kV line project circuit 3 from Quang Trach to Pho Noi. The Quang Trach - Quynh Luu project is 226 km long, passing through the provinces of Quang Binh, Ha Tinh, and Nghe An. The project has 463 column foundation locations, of which 237 column locations cross mountains, passing through many complex terrains. Of the 197 corridor anchorages, 7 anchorages cross rivers and large lakes, and 15 anchorages cross national highways. Photo: Cuong Dao

The project was implemented from January 18, 2024, and the investor-level Acceptance Council met on August 24, 2024 and agreed to connect to the power grid. Photo: Cuong Dao

In Nghe An province, the project is about 100km long, including 202 column foundation positions and 85 corridor anchorages, passing through 6 districts and towns: Hoang Mai, Quynh Luu, Yen Thanh, Dien Chau, Nghi Loc, Nam Dan. Photo: Cuong Dao

Trong quá trình triển khai, dự án luôn nhận được sự quan tâm chỉ đạo của Thủ tướng Chính phủ, các bộ, ngành, lãnh đạo Tập đoàn Điện lực Việt Nam. Cùng với đó là sự ủng hộ của các cấp chính quyền nơi có dự án đi qua, sự đồng lòng, chung sức của người dân đã nhường đất cho dự án, đã tham gia hỗ trợ thi công giai đoạn đào đúc móng.

_nda1317(1).jpg — Unfavorable weather conditions included many days of rain, storms, thunderstorms, extreme heat, many days of strong winds lasting from 3 to 7 hours, and thunderstorms, so construction had to be stopped at many times to ensure the safety of workers and construction equipment.

Once completed, the project will help reduce the load and avoid overloading of existing 500kV lines, ensuring the N-1 criteria, especially when the transmission capacity is high along the Central - North interface at a time when hydropower plants in the North have low generation. Photo: Cuong Dao
