The successful acceptance of 1000 kV UHV ac test demonstration project from Southeast of Jinzhou to Nanyang to Jingmen indicates that China has mastered the core field of UHV AC transmission technology. Among them, 90% of the power equipment used in this project has been made in China, which fully proves that China's independent power enterprises have been qualified for the equipment production needs of UHV transmission lines, and the manufacturers of UHV equipment of China's power grid have also been ranked among the world's first-class manufacturers.

       Through engineering practice, China's power grid research Department has recently issued various new standards for UHV circuits, including equipment standards and production enterprise standards, which will have a certain impact on China's power equipment manufacturers and power fittings manufacturers.

      The 12th Five-Year Plan period is an important period for the development of China's power grid, during which the construction of China's power grid will reach an unprecedented new speed. With the power equipment manufacturing enterprises and electric power production enterprises need a new opportunity in this market situation, do a good job in dealing with in strict accordance with national standards of power grid production in line with the technical specifications of the products, and spend a lot of money for the improvement of the independent property rights products and technology as well as the specification, all of this will be a power with production enterprise core competitiveness under the new opportunity.

      Under the promotion of the 12th Five-Year Plan, the government's 800 kV uHV transmission line from Xiangjiaba to Shanghai has been officially put into use. At full operation, Xiangjiaba can deliver 320 gigawatt hours of electricity to Shanghai and its surroundings. This is a milestone for China's uHV transmission lines and heralds a new direction in the construction of China's power grid lines in the 12th Five-Year Plan.

       The core technology of uHV line has been mastered and Chinese power equipment manufacturers are facing a process of reshuffle. Electric power equipment manufacturers with highly independent property rights and strong technology and production capacity will become the new favorites during the "twelfth Five-Year plan" period, while the original established manufacturers will be eliminated by The Times.
