Xinjiang Tacheng Toli 750 kV transmission project is fully connected

China News Service, Urumqi, November 11 (Ma Yeye, Gao Liang, Jiang Yong, Zhao Ming) The 750 kV transmission project of Xinjiang Tacheng Toli 2×660,000 kilowatt coal power project was fully connected on the 10th. This project creates conditions for the scheduled operation of supporting coal power projects and further improves the energy supply level in northern Xinjiang.

It is understood that the project will start in August 2025. 39.297 kilometers of new lines will be built and 103 towers will be erected. It will mainly serve the Tuoli coal power project to connect to the Xinjiang 750 kV main power grid. Previously, the central and western regions of Tacheng had long relied on the 220 kV power grid for power supply, and the grid carrying capacity was limited, making it difficult to undertake the implementation of large-scale supporting power supplies. After the project is completed, it will make up for the shortcomings of the local power grid and meet the growing demand for regional electricity.

The entire line of the project passes through the Laofengkou and Mayitas wind zones, where there are more than 150 windy days of level 8 or above per year, posing huge challenges for overhead wiring, foundation anchoring, and wire protection. The line passes through alluvial plains, low mountains and hills, and the geological conditions are complex, making pile foundation construction difficult. There are dense intersections and crossings along the line, and some sections are stacked with multiple crossings, which is the biggest construction difficulty of the entire line.

The construction team took multiple measures to solve the construction problems, using reinforced iron towers, V-shaped windproof strings, and porcelain insulators to improve the wind resistance of the lines. "In response to the safety risks of high roadbed crossing railways, highways and multiple power lines, we adopted full-scale network closure and power outage to cooperate with construction. The railway crossing sections were organized and laid out according to 'one gear, one section' to compress the scope of high-risk operations; we reviewed the geological conditions one tower at a time and dynamically adjusted the foundation pit plan. , Strictly implement the strong wind early warning and shutdown mechanism, carry out tower assembly and wire erection at staggered peaks, and seize the effective construction window period." Gao Liang, project manager of the Transmission Construction Branch of Xinjiang Power Transmission and Transformation Company, said that the project will simultaneously increase personnel and equipment to fully cope with the construction schedule pressure caused by severe weather in windy areas.

In the next step, State Grid Xinjiang Electric Power will promptly carry out finishing work such as eliminating line shortages, keep a close eye on the commissioning node, ensure that the project delivers power on schedule, and continue to provide support for stable energy supply in northern Xinjiang and high-quality development of the local economy.
