The power fittings supporting the UHV power transmission and transformation project were recently developed by Wenzhou Nailide Power Technology Co., Ltd. These products will provide supporting support for the construction of UHV backbone grid and directly serve the first 1000 kV AC UHV test and demonstration project under construction in China

Power fittings are metal accessories that connect and combine various devices in the power system and play a protective role. In the review and acceptance organized by the State Grid Corporation of China and the Ministry of science and technology, the experts of the Acceptance Committee agreed that the development of UHV fittings has filled the gap of domestic UHV power fittings, and the research results have reached the international advanced level. The sample has reasonable design and excellent performance, which can meet the construction needs of UHV AC transmission line project.

Known as the world's first "power highway", China's 1000 kV high voltage AC test demonstration project is under intensive construction and is planned to be put into commercial operation this year. At the same time, ± 800 kV DC UHV project Yun Guang line was also started recently. Wenzhou Nailide is stepping up the production of UHV power fittings to meet the construction needs.
