Reliable electrical components engineered for global power infrastructure.
Located in Yueqing, Zhejiang Province, known as the "Electrical Capital of China," Wenzhou Shuguang Fuse Co., Ltd. is a leading power technology enterprise. We integrate professional research, development, production, and sales services under one roof.
Our journey began in 1992 as the "Yueqing Shuguang Fuse Factory." For over three decades, we have evolved into a major force in the global electrical protection market, specializing in FCO (Fuse Cut Out) systems and high-voltage fuse solutions.
Understanding the critical role of Fuse Cut Outs in modern energy grids.
As the global demand for electricity surges, the Fuse Cut Out (FCO) market has become a cornerstone of distribution network safety. In the current industrial climate, FCOs are not merely components but critical safeguards for distribution transformers and overhead lines against overloads and short circuits. From the rapid urbanization in Asia to the grid modernization projects in North America and Europe, FCO suppliers are facing a period of unprecedented demand.
The industry is shifting toward Smart Grid Integration. Modern FCOs are being designed with advanced materials like silicone rubber (polymeric) to replace traditional porcelain, offering better performance in polluted or high-salinity coastal areas. Furthermore, there is a growing trend toward "Eco-friendly" designs that minimize environmental impact during the manufacturing and disposal cycles.
Global utility companies and EPC contractors now demand more than just a product; they require compliance, reliability, and technical support. Procurement strategies are focusing on manufacturers that can meet diverse international standards such as IEC, ANSI, and DIN. Reliability in extreme temperatures and resistance to corrosion are top priorities for buyers in the Middle East and Southeast Asia.
Meeting the world's most stringent quality requirements.
Wenzhou Shuguang Fuse is designated by the Ministry of Electric Power Industry to produce high-voltage fuses of various voltage levels. Our products have passed 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.
International Standards Compliance: Our performance tests meet ANSIC37.42, DIN43625, BS2692, IEC282-2-1995, IEC60644, IEC60470, IEC60282-1, IEC269-2, GB15166.1, GB15166.2, GB15166.5, GB13593, DL/T640-1997, and VDE0636 standards.
Harnessing the power of the world's most robust electrical supply chain.
Chinese factories in Yueqing have access to a complete ecosystem of raw materials—from high-grade porcelain and specialized polymers to precision-engineered copper and silver components. This proximity reduces lead times and ensures competitive pricing.
Leveraging AI-driven quality control and automated assembly lines, Chinese suppliers like Shuguang Fuse can produce large volumes without compromising the precision required for high-voltage protection.
As a dedicated factory, we can customize FCO designs to meet specific local grid requirements, whether it's adjusting the BIL (Basic Insulation Level) or adapting the mounting hardware for different pole configurations.
Innovative solutions for real-world power challenges.
In recent years, our company has developed rapidly, and its economic and social benefits have improved significantly. We continue to deepen and improve the quality management system. 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.
The "Shu Rong" brand products enjoy a high reputation globally. We export to Southeast Asia, the Middle East, Africa, Europe, and various provincial power companies within China. Our sales rank among the top in the industry.
Precision-made fuses, insulators, and holders for every voltage requirement.
We sincerely welcome customers from home and abroad to discuss cooperation and work together for the prosperity of the electric power industry.
