Wenzhou Shuguang Fuse Co., Ltd. is strategically located in Yueqing, Zhejiang Province, famously recognized as the "Electrical Capital of China." As a premier power technology enterprise, we integrate research, development, production, sales, and service to provide world-class circuit protection solutions.
Our journey began in 1992 as the "Yueqing Shuguang Fuse Factory." Over the past three decades, we have evolved from a local workshop into a global powerhouse in the fuse industry. Our commitment to excellence has earned us the designation by the Ministry of Electric Power Industry to produce specialized high-voltage fuses, current-limiting fuses, and zinc oxide arresters.
In the modern era of Industrial 4.0 and the global transition toward Renewable Energy, the demand for reliable general-purpose fuses has skyrocketed. From massive solar farms in the Sahara to high-speed rail networks in Europe, fuses act as the critical last line of defense against catastrophic electrical failures.
The global circuit protection market is projected to reach billions by 2030. The rise of Electric Vehicles (EV) and Smart Grids requires fuses that can handle higher DC voltages and offer faster response times. As a China-based manufacturer, we sit at the heart of this supply chain, providing scalable ODM solutions for global brands.
We are seeing a shift towards "Smart Fuses" integrated with sensors for real-time monitoring. Additionally, environmental sustainability is driving the development of fuses using lead-free and recyclable materials, adhering to strict RoHS and REACH standards.
International buyers are no longer just looking for the lowest price; they demand Technical Compliance. Whether it is DIN43625 for the European market or ANSI C37 for North America, we ensure every unit meets the specific legal and technical requirements of the destination country.
Quality is the cornerstone of Wenzhou Shuguang Fuse Co., Ltd. Our products undergo rigorous testing at the high-power test station of the Electric Power Research Institute and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.
Strict Adherence to International Standards:
Our highest technical performance meets: ANSI C37.42, DIN 43625, BS 2692, IEC 60282-1, IEC 60644, IEC 60470, VDE 0636, and Chinese national standards like GB 15166.1 and DL/T 640-1997.
Protecting transformers and distribution lines from overcurrent in urban and rural power networks.
Critical protection for PV inverters and wind turbine control systems against transient surges.
Ensuring the safety of high-capacity motors and industrial capacitors in manufacturing plants.
In recent years, the company has developed rapidly, and its economic and social benefits have improved significantly. While vigorously developing new products, we have always attached importance to the process flow. High-quality raw materials and sophisticated testing equipment are the backing of our quality assurance system. All performance indicators are in line with the corresponding technical conditions, and new products can be customized and produced at any time according to user needs. "Shu Rong" brand products have enjoyed a high reputation among domestic and foreign users.
