The NANYANG -- Jingmen -- Changsha 1000KV UHV AC project has been completed and will be put into operation in late October.
Nanyang -- Jingmen -- Changsha UHV line project is an important part of the "Day" ring network in Central China. After the project is put into operation, it will significantly enhance the power exchange capacity between provinces of Henan, Hubei and Hunan, which is of great significance to the economic and social development in Central China.
The Nanyang -- Jingmen -- Changsha 1000kV UHV AC project is 625.8 kilometers long, passing through Henan, Hubei and Hunan provinces. Hunan is about 169.6 km in length, put into operation after the completion of the project will be the article 3 provinces of hunan, uhv channel for hunan province increased 2 million kw to 3 million kw of power supply capacity, equivalent to 7% to 8% of the total in hunan power grid, in hunan province given to enhance the skills and the ability to transition between provinces, for the stability of the power grid more reasonable, In Henan, Hubei and Hunan, if any province is short of electricity and the other provinces have surplus, electricity can be sent to the corresponding power-short area through the UHV AC grid.
According to the scene to understand, from hunan province co., LTD. Is responsible for the installation of electricity transmission &transformation facilities of 1 million v high voltage engineering nanyang - jingmen - changsha route engineering bid (12), from yueyang pingjiang xian Wu mouth town taking home village (large N6060 tower side including N6060), stop at 1000 kv, 2nd line via yueyang pingjiang xian, changsha xingsha. A total of 105 steel pipe towers with the same tower and double loops have been built, and the length of the line is about 50.662 kilometers (all of them are erected with the same tower and double loops). There are 78 bases in Changsha County and the length of the route is about 37.635 kilometers, passing through Taoyuan Village, Shanghua Village, Kaihui Town, Tuijia Village, Jinjing Town, Baishi Village, Weihan Village, Bailu Village, Jinghua Village, Shangshan Village, Mingyue Village, and Wannianqiao Village, Shuanghong Village, Huaqiao Village and Huangqiao Village in Changsha County.
According to Zou Tonghua, chief engineer of Nanyang -- Jingmen -- Changsha UHV AC Line Engineering Project, the bidding section was started in June last year, and has completed all the parameter testing tasks, and is expected to be put into operation in late October. He said, on-site construction process, the full use the company independent research and development as the foundation construction of turbine drill for foundation excavation, group tower all adopt the derrick for landing, stringing the 2 x 1 4 the feeding process, more than five times as much as foundation construction efficiency, group construction, efficiency more than 1 times, averaging effectively guarantee the construction efficiency and safety, After the project is put into operation, it can effectively meet the electricity demand of industry, commerce and residents in all periods of the year in Hunan.
