Nanjing Provincial Industrialization Project Accepted Acceptance

Under the jurisdiction of the Nanjing Electric (Group) Co., Ltd. under the jurisdiction of Baiyun Electric Group Co., Ltd., the special fund project for the transformation of scientific and technological achievements in Jiangsu Province, “R&D and Industrialization of Tempered Glass Insulators for UHV Transmission Lines,” has recently passed acceptance. Since the project was implemented for five years, Nanjing Electric independently developed a series of UHV tempered glass insulators and realized industrialization. Its comprehensive technical performance index has reached the leading level of similar international products.

On September 19, commissioned by Jiangsu Provincial Department of Science and Technology, the Nanjing Science and Technology Commission held a special fund project for scientific and technological achievements conversion in Jiangsu Province under the auspices of Nanjing Electric Co., Ltd. “R&D and Industrialization Project of Toughened Glass Insulators for UHV Transmission Lines”. Acceptance meeting. The acceptance expert group consists of five technical experts from Southeast University, West Jiaotong University, China Electric Power Research Institute, East China University of Science and Technology and Jiangsu Provincial Academy of Electric Power, and two certified public accountants of Notary Tianye. The acceptance experts listened to Nanjing Electric's project work summary report, technical research and development and industrialization construction report, reviewed the project's relevant technical documents, audit reports and financial vouchers, and conducted on-site inspections. The acceptance panel believes that the project acceptance data is complete and standardized and meets the acceptance requirements. The project has fully completed all the objectives and tasks specified in the contract and has unanimously agreed to pass the acceptance.

High-strength, large-creepage-span suspension insulators are essential for the suspension, tensioning, and insulation of superconducting (high) power transmission projects. In order to accelerate the R&D and industrialization of toughened glass insulators for UHV transmission lines and to meet the needs of national power construction, the company undertook the project in 2009. The target products are 500kV～1000kV UHV AC, ±600kV～±800kV tempered glass insulators for UHVDC transmission systems, including AC and DC products with strength classes of 300kN, 420kN, and 550kN, which are the key insulators and glass for UHV transmission lines. High-end products in insulators.

During the implementation of the project, around the objectives of the project, the company set up a project headquarters and implemented a division of labor responsibility system to ensure that the target was achieved during the project implementation period. The project implements special funds for special account management. Under the strong support of the Provincial Special Fund for Scientific and Technological Achievement Transformation, the company closely focused on the needs of UHV construction, and through digestion and absorption of imported technology and continuous independent innovation, it conquered high-strength, large creepage distance DC glass formulations and insulating pieces umbrella tray shape, glass Technical breakthroughs such as molding process and high-temperature sensitivity, realizing breakthroughs in innovation, mastering core technologies, successfully developing a full range of UHV tempered glass insulators, achieving industrialization, meeting the needs of UHV transmission projects, and replacing import. The products passed the inspection of the national authoritative testing agency and the product technical appraisal organized by the National Energy Administration concluded that “the comprehensive technical performance index of the product has reached the leading level of the international similar products”. In particular, 830kN DC tempered glass insulators have the highest strength levels in the world. The project actually completed an additional investment of 120 million yuan, and the target product has an annual output of 2 million. During the project implementation period, a total of 8 patents were filed, including 3 invention patents, and the industrialization project contract was completed. The total market share of the company's economic output and leading products is the highest in the domestic industry.

Since 2011, the company has undertaken the UHV DC project of the State Grid Jinsu Line, the UHV DC project of the South China Power Grid, the UHV AC project of the Huaishang Line of the State Grid, the UHVDC project of the Ha-Zheng Line, and the Xi-Zhe Line. The production tasks of the glass insulators used in the high-voltage direct-current project and the Zhe-Fu line UHV AC project will contribute to the construction of key national projects such as “West-to-East Electricity Transmission”, “Shudong-East Power Transmission” and “Jiangdong Power Transmission”.
