Founded in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a global powerhouse in the electrical equipment industry. Nestled in Yueqing, Zhejiang—famously known as the Electrical Capital of China—we are a specialized power technology enterprise integrating R&D, manufacturing, and global sales.
As a leading China Fuse Voltage Manufacturer, our 30-year legacy is built on a foundation of rigorous testing, engineering innovation, and a deep understanding of power grid safety. We don't just sell fuses; we provide critical protection for infrastructure that powers modern civilization.
Our commitment to reliability is backed by prestigious certifications and testing from the world's most rigorous electrical research institutes.
Our products are engineered to meet and exceed IEC60282, DIN43625, BS2692, and ANSI C37.42 standards, ensuring seamless integration into any global power system.
Passed quality audits by the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute.
Operating under a complete quality assurance system certified by ISO9001:2000, ensuring every unit leaving our factory is of peak performance.
The global Medium and High Voltage Fuse market is currently undergoing a massive transformation. With the worldwide shift toward Renewable Energy (Solar and Wind), the demand for specialized current-limiting fuses has surged. These power systems require components that can handle fluctuating loads while providing lightning-fast interruption during faults.
As an industry leader, Wenzhou Shuguang Fuse Co., Ltd. is at the forefront of this trend. We have developed specialized HV HRC Fuses specifically designed for transformer protection in solar farms and wind turbine substations. Our products are engineered to withstand harsh environmental conditions, from the humid tropics of Southeast Asia to the freezing industrial zones of Northern Europe.
The rise of Electric Vehicles (EVs) has also introduced a new localized application scenario. High-speed, high-voltage DC fuses are now essential for charging stations and battery protection. Our factory has invested heavily in R&D to provide EV Fuse solutions that meet the rapid response times required for automotive safety.
Furthermore, Urbanization in Africa and the Middle East has led to massive grid expansions. Procurement managers in these regions seek high-performance Drop-out Fuse Cut Outs and Polymeric Insulators that offer durability and ease of maintenance in remote areas. Our "Shu Rong" brand has become a trusted name in these markets due to our balance of high-end quality and competitive manufacturing costs.
Located in the heart of China's electrical hub, we have immediate access to high-purity raw materials and world-class logistics, reducing lead times for large-scale global orders.
We don't just offer off-the-shelf products. Our engineering team can customize fuse links and voltage ratings based on specific utility requirements or unique industrial applications.
Utilizing high-quality raw materials and sophisticated testing equipment, we ensure every batch meets the technical indicators of GB15166 and VDE0636 standards.
