On April 30, in the in the industrial park of ZZZN Electromechanical Technology Co., Ltd. a subsidiary of SDZN Magnetic Materials Technology Co., Ltd. a batch of split-lobed large-scale wind power stator coils are being packed and they will be shipped to Europe.
"This is another new type of electromagnetic coil product successfully developed by ZZZN. This product adopts a split design and can be assembled on site, breaking the original limitation of the bulky electromagnetic coil used in large-scale wind power." ZZZN technical engineer Wang Shufeng proudly We introduced, "It is expected that the company's sales revenue will exceed 1 billion yuan this year."
The reason why the high-speed railway generators in China can run normally safely and steadily is all due to the use of a high-performance polyimide film insulation material-"gold film", which is at -269℃～400 Within the range of ℃, it has the characteristics of radiation resistance, high heat resistance, non-combustion, high toughness and low loss.
But for a long time, the research and development and production technology of this material have been completely monopolized by international giants such as the US "DuPont".
After 5 years of R&D investment, "ZZZN Electromechanical" finally successfully developed a high-end corona-resistant film for electromagnetic wires, and its corona-resistant time is even longer than DuPont products. "After the process test is stable, it will be put into mass production to achieve localization." Wang Shufeng said.
ZZZN has successively developed 19 projects, completed 19 scientific and technological transformations, and established a municipal copper-based electromagnetic wire test center. The products are supplied to domestic and foreign well-known enterprises such as CRRC, Dongfang Electric, Harbin Electric Plant, ABB Group, Siemens, and Bombardier.
In 2019, ZZZN successfully developed a split-type large-scale wind power stator coil, strived to open up overseas markets, and successfully entered the electromagnetic energy market for clean energy.
A single electromagnetic wire connects the electromagnetic wire market in the fields of clean energy, new energy vehicles, and rail transportation.
