The largest ultra-high voltage cable project in China—Relocation of overhead lines on polymer suspension insulators in northeast Xi’an

On February 26, the State Grid Shaanxi Economic Research Institute completed the feasibility study on the relocation of 330 kV overhead transmission lines in northeast Xi’an, laying a solid foundation for the project’s deployment and follow-up work.

The 330 kV line relocation project in northeast Xi’an includes the 330 kV line relocation project such as Xi’an Olympic Sports Center, Xi’an Silk Road International Exhibition Center, Xi’an Silk Road International Conference Center, and the 330 kV line landing project in North Square of North Passenger Station. The area where the project is located involves Xi’an International Port Area, Xi’an Chanba Ecological Area, Weiyang District, and Xi’an Economic and Technological Development Zone. It is currently the largest ultra-high voltage cable project in China. After the completion of the project, the 330 kV overhead line corridor in northeast Xi’an will be opened to further strengthen the main grid structure of Xi’an Power Grid and serve as the Olympic Games Center and its auxiliary facilities in the International Port Area Urban Games, the Tencent Town Project in the Chanba Ecological District, Road International Conference and Exhibition Center and other key projects provide favorable conditions, which will further improve the reliability and safety of regional power supply, which are important for enhancing the comprehensive carrying capacity of Xi’an city, improving the human settlement and urban three-dimensional space environment, and promoting regional economic and social development. significance.
