Group company was invited to attend the grid connection and operation ceremony of Hexi 750 kV transmission and transformation project
The 750 kV transmission and transformation project in Hexi is the No.1 Project in Gansu Province this year, and also the No.1 Project of State Grid Corporation of China. Gansu section of the project is divided into wusheng Hexi 750 kV transmission and transformation project and Hexi Jiuquan Dunhuang 750 kV transmission and transformation project. The project includes the construction of three 750 kV substations in Hexi, Jiuquan and Dunhuang, the expansion of the 750 kV Substation in wusheng and three 750 kV transmission lines in wusheng Jiuquan Dunhuang. The total length of the line is 2 × 841km, and the capacity of transformer is 8.4 million KVA. The total investment of the project is 7.16 billion yuan. At present, the substation and line engineering of the project have been completed and put into operation with electricity.
The completion of Hexi 750 kV transmission and transformation project has realized the Gansu new grid connection, realized the upgrading transformation of Gansu Power Grid from 330 kV main grid to 750 kV main grid, will provide transmission conditions for Jiuquan 10 million kilowatt wind power and supporting 10 million kilowatt thermal power, and form an export-oriented northwest power transmission end grid, which reflects the strategic intention of State Grid Corporation of China to build the same strong smart grid At the same time, the construction of the project will also meet the electric high-speed railway power consumption and the growing industrial and agricultural production power consumption in Hexi region, and will make new contributions to the economic and social development of Gansu Province and the realization of the national energy development strategy.
In this project, our group company is responsible for the delivery of fittings and busbars of three substations, and also participates in the improvement and update of relevant design, making a little contribution to the construction of national grid.
