B[Zhejiang UHV AC Ring Network Project Completes First Base Tower Assembly] On November 10th, Zhejiang UHV AC Ring Network Project completed the first base tower assembly in Shangyu, Shaoxing, marking that the project has fully entered the tower assembly stage. As a key power development project in the country’s “15th Five-Year Plan”, the Zhejiang UHV AC ring network project has a total investment of 29.3 billion yuan. The project starts from Jiaxing, passes through Hangzhou, Shaoxing, Ningbo, Taizhou, and Wenzhou, and ends in Lishui. Three UHV substations in Jiaxing, Ningshao, and Wenzhou are newly built, Liandu UHV substation is expanded, 508 kilometers of double-circuit lines are built, and GIL pipe corridors are used to cross the Qiantang River. A total of more than 2,000 new iron towers are needed for the entire line. There are dense crossings and spans along the line and the construction environment is complex. The first bid section to be constructed this time includes 6-base iron towers, which need to span the 500 kV transmission line under reconstruction. The project took advantage of the power outage window period of the power grid to optimize the operation process, and configured multiple sets of mechanized equipment according to the mountainous terrain to promote the simultaneous assembly of multi-base towers to ensure the safe and orderly progress of the construction of key span sections.

Among them, the ±1100 kV Zhundong-Wannan, ±800 kV Hami South-Zhengzhou, and ±800 kV Hami-Chongqing UHV DC transmission channels transmit 53.89 billion, 35.33 billion and 27.67 billion kilowatt hours respectively, accounting for nearly 90% of the total external power transmission.

Currently, the wind power, photovoltaic, solar thermal, supporting energy storage, and UHV DC transmission projects of the new energy base in the central and northern part of Kubu are under simultaneous construction. After the base is fully completed, it will be able to deliver approximately 40 billion kilowatt-hours of electricity to Beijing, Tianjin and Hebei every year, assisting the comprehensive green transformation of economic and social development.
