The Dianzhong Water Diversion Project Dali Section 1 Xianglushan Tunnel construction power supply design and construction general contracting project has successfully completed the power supply commissioning task.

Recently, the power supply design and construction general contracting project for the Xianglushan tunnel construction of the Dali Section I of the Dianzhong Water Diversion Project of the company's Third Engineering Project Department successfully completed the power supply commissioning task of the 35KV Zhongdeng substation opposite interval, 34# vertical shaft (Qingping) substation, 6# branch tunnel (Fuhe) substation, and 33.2 kilometers of double-circuit lines on the same tower.

During the project construction, faced with difficulties such as high risks in substation transformation and short effective operation windows, the project department gathered wisdom and worked together to ensure the project's progress. It successively completed the transformation of the opposite interval and line protection devices of the Zhongdeng substation, the optimization of the background five-prevention system data, and the verification of dispatching signals. At the same time, it also completed the debugging of the protection devices of the substation and lines, and the linkage debugging of the three substations, laying a solid foundation for the smooth commissioning of the project.

Through the unremitting efforts of the project department, the project was successfully energized at the first attempt, not only winning high praise from the Dianzhong Water Diversion project owner, but also further demonstrating the project department's professional strength and maintaining the company's good brand image.
