Established in 1992 as the "Yueqing Shuguang Fuse Factory," our journey began in Yueqing, Zhejiang—the renowned "Electrical Capital of China." With over three decades of specialized experience, we have evolved into a powerhouse of technology, integrating R&D, production, sales, and comprehensive service for the global power industry.
As a leading Wholesale General Purpose Fuses Manufacturer, we possess the technical depth to safeguard critical infrastructure. Our commitment to excellence is rooted in our history of supporting China's Ministry of Electric Power Industry, providing voltage levels that meet rigorous national and international requirements.
General-purpose fuses are no longer just commodities; they are critical safety valves in the modern era of smart grids and renewable energy. From the busy industrial hubs of Europe to the rapidly expanding infrastructure in Southeast Asia and Africa, the demand for high-reliability circuit protection is at an all-time high.
The global shift toward EV (Electric Vehicles) and Solar PV systems has redefined the fuse industry. We are at the forefront, manufacturing specialized DC fuses and high-voltage current-limiting links that handle the unique load profiles of green energy sources.
As factories move toward Industry 4.0, the precision of general-purpose fuses becomes paramount. Our products protect sensitive PLC controllers, robotics, and complex motor circuits against transients that could lead to costly downtime.
Our manufacturing process adheres to the highest global standards, ensuring that every fuse leaving our factory provides unwavering protection under extreme conditions.
Our products are designated by the Ministry of Electric Power Industry for producing a wide array of protective equipment. We have successfully passed the high-power test stations of the Electric Power Research Institute and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.
Whether it's oil-immersed transformer protection in the humid environments of Southeast Asia or drop-out fuse cutouts for rural electrification projects in South America, we understand the environmental challenges. Our porcelain and polymer insulators are engineered for UV resistance and high pollution tolerance.
Global wholesalers and EPC contractors require a manufacturer who can provide consistent quality and stable lead times. By leveraging our massive production capacity in Yueqing, we offer the dual benefit of high-end engineering and competitive wholesale pricing.
In recent years, Wenzhou Shuguang Fuse Co., Ltd. has prioritized process flow optimization. We utilize high-quality raw materials (such as 99.9% pure silver elements and high-strength alumina ceramics) and sophisticated testing equipment to ensure every performance indicator meets technical conditions.
Our "Shu Rong" brand has earned a high reputation among users for its reliable performance in substation, distribution, and industrial power systems.
The company adheres to the principle of "Development by science and technology, and survival by quality". While vigorously developing new products, we have always attached importance to the rigorous testing of every unit produced.
We recognize that every electrical grid has unique parameters. New products can be customized and produced at any time according to user needs, whether it's specific current ratings or non-standard dimensions.
A complete sales network has been formed throughout China and across international borders. Our high-voltage current-limiting fuses are exported to Southeast Asia, the Middle East, Africa, and Europe, ranking us at the top of the industry.
We sincerely welcome customers from home and abroad to discuss cooperation and work together for the prosperity and development of the electric power industry. Let us create a brilliant future together with reliable circuit protection technology.
