Reporter August 21 from the National network of Xuzhou power supply company learned that Huainan-Nanjing-Shanghai 1 million kv AC UHV transmission and Transformation Project Su-Tong Gil Comprehensive pipe Corridor tunnel August 21 through. Gil refers to the gas insulated metal closed transmission line, the use of metal conductive rod transmission, and sealed in the grounding of the metal shell, through the pressure to achieve gas insulation.
Compared with the conventional cable, Gil has large transmission capacity, small loss, unaffected by the environment, high reliability, save land and other notable advantages, especially suitable for the overhead transmission mode or cable transmission under the condition of the supplementary transmission technology. Huainan-Nanjing-Shanghai 1 million kv AC UHV transmission and Transformation Project is one of the 12 transmission channels of the State Council's air Pollution Control action Plan, which is an important part of East China UHV main network frame. After its completion, Huainan-Nanjing-Shanghai project will be carried out with the transport of Anhui-Anhui-China East Huainan-Southern-Shanghai project, the formation runs through Anhui, Jiangsu, Zhejiang, Shanghai Load center of the East China UHV AC Ring network, which is also the world's first UHV AC dual-ring network, will greatly improve the East China power grid to receive external calls to enhance the level of safe operation of the grid,
It is of great significance to promote the sustainable development of economy and society in East China and Jiangsu Province and further improve the level of electric power technology.

Sutong Gil Comprehensive pipe Gallery August 2016 started construction, from Xuzhou, Jiangsu Province, the end of the Yangtze River, Jiangsu Nantong, spanning the north and south, up to 5468.5 meters, the project to refresh a number of records. Sutong Gil Complex Pipe Gallery project will be completed in 2019, is expected to reduce the annual production of coal 100 million tons, emission reduction of 480,000 tons of sulfur dioxide, 470,000 tons of nitrogen oxides, 60,000 tons of soot.
The future, through this tunnel, China will be formed throughout the Anhui, Jiangsu, Zhejiang, Shanghai Load center of the East China Special High-voltage AC ring network. The world's first UHV crossing the Yangtze River complex through the corridor | Create a number of the first
