Shu Guang
Wenzhou Shuguang Fuse Co., Ltd. is strategically located in Yueqing, Zhejiang Province—widely recognized as the Electrical Capital of China. We are a premier power technology enterprise that seamlessly integrates research, development, production, sales, and comprehensive after-sales service.
Our journey began in 1992 as "Yueqing Shuguang Fuse Factory." Over three decades, we have evolved from a local manufacturer into a global powerhouse in the circuit protection industry. Our deep-rooted experience allows us to serve as a leading China ODMEFuses Factory, providing bespoke solutions for complex electrical infrastructures worldwide.
30+ Years of Professional Manufacturing Excellence
Understanding the evolving landscape of global power distribution.
The global shift toward smart grids requires fuses with higher precision and reliability. As a leading factory, we develop high-voltage fuses that integrate seamlessly with modern monitoring systems to prevent catastrophic grid failures.
The rise of solar (PV) and wind energy has created a massive demand for specialized HRC fuses. Our ODMEFuses solutions are designed to handle the unique DC and AC stresses associated with renewable energy inverters and transformers.
International buyers are increasingly seeking "One-Stop Shop" capabilities. We fulfill this need by offering everything from medium voltage DIN standard fuses to porcelain drop-out cutouts, ensuring compliance with IEC and ANSI standards.
AI and IoT are now entering the manufacturing floor. We utilize advanced testing equipment and high-precision process flows to ensure every fuse link meets the rigorous technical conditions required by the modern power industry.

Quality Pass Rate
Our commitment to quality is not just a promise—it is verified by national and international authorities. Wenzhou Shuguang Fuse Co., Ltd. is designated by the Ministry of Electric Power Industry to produce specialized high-voltage equipment.
Our products have undergone rigorous testing at:
Our technical performance standards meet: ANSIC37.42, DIN43625, BS2692, IEC60282-1, IEC60644, and VDE0636.
Leveraging high-tech manufacturing with cost-efficiency.
Unlike standard suppliers, our engineering team can customize fuse parameters (voltage, current, breaking capacity) according to your specific localized application requirements.
Located in Yueqing, we have immediate access to high-quality raw materials—from aerospace-grade ceramics to high-purity silver for fuse elements—ensuring stable lead times.
Our products are exported to Southeast Asia, the Middle East, Africa, and Europe. We consistently rank among the top in the domestic industry for high-voltage current-limiting fuse sales.
Versatile solutions for diverse industrial environments.
Specialized high-voltage fuses designed for capacitor protection, preventing internal fault expansion in large industrial capacitor banks.
Our oil fuse-links (254 x 63.5 mm) are engineered to operate within transformer oil, providing reliable protection for medium voltage distribution networks.
Drop-out fuse cutouts and lightning arresters are essential for rural overhead lines, where ease of maintenance and environmental resistance are critical.
High-breaking capacity HRC fuses protect urban switchgear, ensuring that faults are isolated without damaging expensive infrastructure in dense city centers.
Our factory adheres to the principle of "Development by science and technology, and survival by quality". We have invested heavily in sophisticated testing equipment that monitors every phase of the production process.
Our "Shu Rong" brand is synonymous with high reputation. Whether it is a standard 10kV miniature fuse link or a custom 36kV HRC fuse, we ensure that every performance indicator exceeds industrial standards. We don't just sell fuses; we sell security and peace of mind.
