In 2021, the company undertook an intelligent upgrade and transformation of its existing Workshop No. 2, with the aim of establishing a state-of-the-art, smart manufacturing facility dedicated to producing high-end enameled wire for new-energy vehicle motors. The upgrade project encompasses the introduction of enameling machines, digital testing equipment, intelligent control systems, automated production lines, online inspection devices, as well as a three-dimensional warehouse and associated supporting infrastructure. The core objective of this transformation is to develop enameled wire tailored for high-power drive motors in new-energy vehicles, thereby broadening the company’s product portfolio and strengthening its market competitiveness.
In April 2022, at a new-product and new-technology appraisal conference hosted by the China Machinery Industry Federation, a review panel comprising academicians of the Chinese Academy of Sciences and numerous industry experts evaluated the company’s independently developed “Corona-Resistant High PDIV Enameled Copper Flat Wire for 800V Drive Motors in New Energy Vehicles.” Following rigorous deliberation, the product was recognized as achieving an internationally leading level among comparable products in terms of its comprehensive performance metrics.
Currently, thanks to the aforementioned technological innovations, the company has successfully secured orders from numerous domestic and international new-energy vehicle manufacturers and motor producers. Notably, we have also been recognized as a qualified supplier by VinFast, a well-known Vietnamese new-energy vehicle manufacturer listed on the NASDAQ in the United States (stock code: VFS).
In early 2024, the company invested in the construction of a connecting structure between the existing No. 1 and No. 2 workshops and in the new construction of Factory Building No. 4, adding fully automated equipment, including three extrusion units, three enameled wire winding machines, and three transposition machines. This equipment was commissioned in November 2024, resulting in an output value of RMB 505 million in 2024 and RMB 809 million in 2025—a year-on-year increase of 60%. As a subsidiary of Hongyuan Co., Ltd., the company has overachieved all assigned tasks.
Leveraging state-of-the-art process equipment, sophisticated manufacturing technologies, reliable product quality, and a commitment to superior service, the company has earned widespread praise and recognition from numerous customers.
The path of innovation is the “lifeblood” of an enterprise. Under the leadership of Chairman Yang Xiqing, Shenyang Changsheng Electrical Equipment Technology Co., Ltd. will always remain true to its original aspiration and keep its mission firmly in mind, working diligently and down-to-earth, leveraging wisdom and hard work to develop and manufacture high-quality new products that continuously meet the product-use needs of its broad base of strategic partners.
