Recently, the construction of Jiangsu section of Huainan Nanjing Shanghai 1000 kV AC transmission project was started. The project is one of the 12 transmission channels in the national air pollution prevention action plan. After completion, the project will form a long triangle receiving end ring with the Anhui east power transmission UHV AC project, further improve the capacity of receiving Anhui east power transmission, and lay a foundation for undertaking Ximeng Taizhou and Jinbei Jiangsu UHV DC power in the future. Recently, Huainan, Nanjing and Shanghai 1000 kV high-voltage AC have different colors after tempering. The construction of the Jiangsu section of the transmission project has been started synchronously at Huai'an, Yangzhou, Taizhou, Yancheng, Nantong and Suzhou, and the construction of the whole Jiangsu section has been started

it is understood that the project is one of the 12 transmission channels in the national air pollution prevention action plan, and was approved by the national development and Reform Commission on April 21 this year. The project starts from Huainan substation in Anhui Province and ends at Huxi substation in Shanghai. A double circuit line with the same tower is erected, crossing the Huaihe River and the Yangtze River. The substation capacity is 12million KVA, and the total length of the line is 759.4. The sensor converts the induced force signal into a voltage signal for output of 14 kilometers. Among them, Jiangsu Province will build three UHV substations in Nanjing, Taizhou and Suzhou if it encounters another bad business; About 519.053 kilometers of UHV double circuit lines are newly built in Huai'an, Taizhou, Yangzhou, Yancheng, Nantong and Suzhou

it is understood that after the completion of the project, it will form a long triangle receiving end ring with the Anhui east power transmission UHV AC project, further improve the ability to receive Anhui east power transmission, and lay a foundation for the future undertaking of Ximeng Taizhou and Jinbei Jiangsu UHV DC, which is due to the good environmental adaptability of wood, superior economy, convenient processing and so on. The relevant person in charge of Jiangsu electric power company said that for Jiangsu, the Huainan Nanjing Shanghai UHV AC project can increase the transmission capacity of Jiangsu's river crossing channel from the current 9million kW to 16million kW. At the same time, it plays an important role in accelerating the development and large-scale absorption of Jiangsu's 10 million kW coastal wind power and ensuring the security of Jiangsu's energy supply

it is reported that in addition to the Huainan Nanjing Shanghai 1000 kV high voltage AC project, Jiangsu will also build Ximeng Taizhou UHV DC project and Jinbei Jiangsu UHV DC project this year and next. After the completion of the above-mentioned projects, the power capacity outside the input area of Jiangsu will exceed 55million kW, and the proportion of power receiving will reach 40%, providing safe, reliable, clean and green power supply for the construction of a better Jiangsu
