Engineered for Global Safety Standards (IEC, DIN, ANSI)
In the modern electrical landscape, the demand for high-reliability circuit protection has never been higher. As a leading China BestPowerFuses factory, Wenzhou Shuguang Fuse Co., Ltd. sits at the heart of the global energy transition. Power fuses are no longer just safety components; they are the critical gatekeepers of smart grids, renewable energy plants, and industrial automation systems worldwide.
The global fuse industry is shifting toward higher voltage ratings and faster response times. With the rise of electric vehicles (EVs) and photovoltaic energy, the industry is witnessing a surge in specialized components like EV fuses and DC current-limiting fuses. Wenzhou Shuguang is pioneering these developments by integrating AI-driven manufacturing processes and rigorous testing to meet these high-tech demands.
Located in Yueqing, the "Electrical Capital of China," our factory benefits from a world-class supply chain. This allows us to maintain a status as a premier BestPowerFuses factory, offering unmatched speed-to-market and competitive pricing without compromising the technical integrity required by international utilities.
Wenzhou Shuguang Fuse Co., Ltd. is a power technology enterprise integrating research, development, production, sales and service. The predecessor of the company was "Yueqing Shuguang Fuse Factory" established in 1992.
With over three decades of experience, we have evolved from a local workshop into a global powerhouse. Our brand "Shu Rong" is synonymous with reliability in high-voltage current-limiting fuses and power capacitor protection. Our tenure in the industry has granted us the unique Expertise to handle complex power requirements across various continents.

Meeting the World's Strictest Standards
It is designated by the Ministry of Electric Power Industry to produce high-voltage fuses of various voltage levels, including zinc oxide arresters, drop-out fuses, and high-voltage insulators. Our products have been rigorously tested at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute.
Adherence to Global Standards: Our technical performance meets or exceeds ANSI C37.42, DIN 43625, BS 2692, IEC 60282-1, IEC 60644, and the VDE 0636 standard. This commitment to compliance ensures that when you source from our factory, you are receiving products that are safe, reliable, and compatible with global power infrastructure.
International procurement officers look for three things: Reliability, Compliance, and Cost. As a primary China BestPowerFuses factory, we address these by providing factory-direct pricing, comprehensive certification documentation, and a quality assurance system that has been refined over 30 years. Whether it's for a grid expansion in the Middle East or an industrial plant in Europe, our fuses provide the necessary protection with long-term durability.
Power environments vary. In Southeast Asia, our drop-out fuses are localized for high-humidity environments. In Europe, our DIN-standard HRC fuses are integrated into compact switchgears. Our ability to customize performance indicators according to user needs—such as specific current-limiting characteristics or environmental resistance—makes us a preferred partner for localized engineering firms.
We use high-quality raw materials and sophisticated testing equipment as the backbone of our quality assurance system. In recent years, we have invested heavily in process flow optimization. This ensures that every "Shu Rong" brand product maintains consistent performance, even in the most demanding high-power test stations.
Wholesale Solutions for International Markets
The choice of a BestPowerFuses factory is a decision for safety and longevity. At Wenzhou Shuguang, we combine the heritage of a 1992 start-up with the cutting-edge technology of a modern powerhouse. Our products are exported to various provincial power companies in China and across Southeast Asia, the Middle East, Africa, and Europe. We form a complete sales network that ensures good business contacts and high industry rankings.
The company adheres to the principle of "Development by science and technology, and survival by quality." We sincerely welcome customers from home and abroad to discuss cooperation and work together for the prosperity and development of the electric power industry. When you partner with us, you are not just buying a fuse; you are investing in a 30-year legacy of electrical engineering excellence.
