Recently, Jinping-Suonan ± 800 kv UHV DC project centralized glass insulator procurement and bidding, Nanjing Electric (Group) Co., Ltd. (hereinafter referred to as Nanjing Electric) won the bid 1300 kilonewton DC tempered glass insulators more than 130,000 . This is the first time that the company's DC glass insulators formally entered the UHV DC transmission project, marking a historic breakthrough in the application of domestic glass insulators in the UHV field.
In the 18 bids for this tender, Nanjing Electric won 12 bids, which accounted for two-thirds of the total bales. The delivery time of the products was divided into three times. In view of the high voltage level, strict quality requirements, large product tonnage, tight delivery time, and heavy production tasks of the Jinsu DC project, the company completed the delivery of the products required by the national key projects on time and in quality. Shen Qirong, general manager of the company, served as general commander of the Jinsu Ultra High Voltage Direct Current Project Headquarters to strengthen the organization and leadership of the project.
Lightning brand tempered glass insulators are Nanjing Nanjing Electric's first domestic specialty products and major export products. It has more than 50 years of production history and operating experience. Through digestion and absorption of imported technology and continuous independent innovation, the company has mastered the world's leading core technology in the research and production of glass insulators, and has all independent intellectual property rights, forming the global (monomeric) largest tempered glass insulator production base, making China The manufacturing level and international competitiveness of glass insulators have been significantly improved. A series of new products of glass insulators independently researched and developed have filled domestic gaps, broken foreign monopolies, and successfully met the needs of national key projects such as the Three Gorges Project and West-to-East Electricity Transmission, and were exported. It has been exported to more than 60 countries and regions, and has become the largest supplier of glass insulator products for the State Grid, China Southern Power Grid and foreign power companies.
After the Jinping-Sulan ±800 kV UHVDC power transmission project is completed, it can realize the optimal allocation of power resources nationwide, meet the growing demand for electricity in East China, and lay the technical foundation for the subsequent western power transmission project. At the same time, this project can improve the independent innovation capability of China's power transmission and transformation manufacturing industry, promote the upgrading of China's power grid technology, and have good economic and social benefits.
It is reported that this project was approved by the National Development and Reform Commission in November 2008; construction was officially started in 2009, and it is planned that the bipolar will be completed and put into operation in 2012.
