Recently, the 550kN large creepage AC glass insulator independently researched and developed by Nanjing Electric (Group) Co., Ltd., which can be used in UHV AC transmission projects, passed national technical appraisal, and its comprehensive technical performance has reached the international advanced level of similar products; the company developed 330kV The 500kV AC Rod Suspension Composite Insulator Series also passed national-level technical appraisal. The product's comprehensive technical performance has reached the domestic advanced level of similar products.
The 550kN (650mm, 710mm) large-climacter AC glass insulators and the 330kV, 500kV AC rod-suspended composite insulators (12 models) developed by Nanjing Electric (Group) Co., Ltd., entrusted by the China National Machinery Industry Council and entrusted by the National Energy Administration The technical appraisal will be held in Nanjing. The expert appraisal committee listened to the summary report of the development of the two types of products, reviewed the appraisal data, examined the production site, and conducted spot testing of the product. It is agreed that: 550kN large creepage AC glass insulators, reasonable structural design, light weight, creepage distance, excellent electrical properties, high mechanical strength, small dispersion, product comprehensive technical performance to achieve the international advanced level of similar products, agreed to pass the technology Appraisal, can be put into production; 330kV, 500kV AC rod-suspension composite insulators using high-temperature vulcanized silicone rubber segmented integral injection molding, mandrel and end fittings pressure-type connection, product design is reasonable, high mechanical strength, small dispersion , Excellent electrical performance, product comprehensive technical performance to reach the domestic advanced level of similar products, agreed to pass technical appraisal, can be put into production.
As the birthplace of China's first toughened glass insulator, Nanjing Electric has been developing and producing glass insulators for more than 50 years. In recent years, after digesting and absorbing imported technology and continuing independent technological innovation, the company has mastered the world's leading core technologies in the research and development and industrialization of high-end glass insulators, and possesses all independent intellectual property rights, which enables the manufacturing level and international competition of China's glass insulators. The force has significantly improved and made important contributions to the national key projects such as the delivery of hydropower from the Three Gorges Project, the transmission of electricity from the west to the east, and the UHV project. The company has thus become the largest supplier of the State Grid Corporation of China and China Southern Power Grid Corporation; it has become the largest supplier of glass insulator products for power companies in countries such as South Africa and India. The company has independently developed 550kN AC and DC glass insulators for the construction of national UHV AC and DC transmission projects, filling the gaps in the domestic market. The comprehensive technical performance of the products has reached the leading level of similar products in the world. High-end products such as 550kN DC glass insulators have been adopted by national key projects such as the Jinsu-Suzhou High-Voltage HVDC project and the China Southern Power Grid project, achieving a major breakthrough in domestic UHV insulators.
It is understood that through product identification, it is of great significance for Nanjing Electric Glass Insulators to further upgrade their products, seize the high-end market, and meet the national UHV AC transmission project construction needs.
