Shanghai Wenlida Technology Company, founded in 1995 and headquartered in Jiading District, Shanghai, is a joint-stock enterprise integrating R&D, manufacturing, sales, and technical services in the field of power quality and voltage regulation equipment. We operate two major R&D and production bases located in Jiading (Shanghai) and Jiashan (Zhejiang) with a combined area of approximately 100,000 square meters. We also collaborate with Shanghai Jiao Tong University’s FACTS Technology Transformation Center, combining academic innovation with industrial expertise to advance solutions for stable and efficient power systems.
With a dedicated in-house R&D team and a comprehensive production chain, Wenlida employs 109 engineering and technical professionals and maintains partnerships with over 800 long-term clients. As one of the drafting units of China’s national standard for voltage stabilizers, we have been deeply involved in the industry for nearly 30 years, accumulating extensive experience in laser processing, printing, and medical applications. Our two major bases located in Jiading and Jiashan, covering 40,000 m² and 53,000 m² respectively, are equipped with modern facilities that ensure efficient production and strict quality control.
Since the establishment, we have focused on the R&D and production of high-power industrial voltage stabilizers, laminated busbars, high- and low-voltage reactive power compensation devices, harmonic filters, low-voltage dry-type transformers, reactors, DC/DC converters, PCS equipment, and a range of integrated power-saving systems. Having experienced and contributed to every key stage of China’s voltage stabilizer industry, we were honored to participate as a co-drafter of the national voltage stabilizer standard. Today, our voltage regulation and power quality systems are widely used across Industry 4.0 smart manufacturing, rail transit, power systems, telecommunications, healthcare, metallurgy, petrochemicals, civil aviation, municipal infrastructure, automotive manufacturing, public transportation, expressways, and renewable energy sectors.
Through continuous innovation and dedication, Wenlida has helped numerous users achieve safe, efficient, and energy-saving power utilization. Our customer portfolio includes both domestic and international enterprises such as Huawei, ZTE, Mitsubishi, Hitachi, Siemens, Doosan, Haier, Heidelberg, Oriental Pearl, FAW, CNPC, China Telecom, and Omron.
Inside our workshop, every stage of production, from precision component machining to final assembly, reflects our commitment to quality and detail.
