The global electrical protection market is undergoing a radical transformation. As countries shift toward Smart Grid technology and renewable energy integration, the demand for "High-Quality ElectroFuses" has skyrocketed. No longer just simple safety devices, modern fuses are critical components in stabilizing power distribution networks.
In the industrial sector, the rapid rise of Electric Vehicles (EV) and high-speed rail systems requires fuses with extreme thermal stability and fast-acting current-limiting capabilities. Manufacturers are now focusing on materials that offer lower power loss and higher breaking capacities to meet these rigorous global standards.
Established in 1992 as "Yueqing Shuguang Fuse Factory," our journey began in the electrical capital of China—Yueqing, Zhejiang Province. Today, we are a leading power technology enterprise integrating research, development, production, and sales.
For over three decades, we have specialized in the manufacturing of high-voltage fuses of various voltage levels, including high-voltage current-limiting fuses, power capacitor protection, zinc oxide arresters, and high-voltage insulators. Our legacy is built on the principle of "Development by Science and Technology, and Survival by Quality."
Our products are engineered for diverse environments, from the extreme humidity of Southeast Asia to the rigid safety requirements of European power grids. We provide tailored solutions for oil-immersed transformers, outdoor distribution lines, and indoor switchgear.
Enterprises worldwide require trust. Our technical performance meets international standards including ANSIC37, DIN43625, BS2692, and IEC60282-1. This ensures seamless integration into existing infrastructure regardless of geographical location.
Understanding that no two grids are the same, we offer customized production based on specific user needs—whether it's unique dimensions for 11kV expulsion links or specific ratings for EV protection fuses.
Our products have successfully passed inspections by the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute. Our quality management system is fully ISO9001:2000 certified.
As a China-based "High-Quality ElectroFuse Manufacturer," we prioritize the use of high-grade raw materials and sophisticated testing equipment. In recent years, our investment in automated process flows has allowed us to increase production capacity without compromising on the precision required for medium and high-voltage protection.
Our "Shu Rong" brand is synonymous with durability. By utilizing state-of-the-art high-power test stations, we ensure that every HRC fuse and drop-out fuse link can handle the thermal and mechanical stresses of modern industrial applications.
Located in the heart of China’s electrical capital, we have instant access to the world’s best copper, ceramic, and polymer suppliers. This allows us to reduce lead times significantly compared to Western counterparts.
Our economy of scale allows us to provide premium IEC-standard fuses at a competitive price point, enabling global utility companies to maintain their grids without exceeding budget constraints.
With a complete sales network exported to Southeast Asia, the Middle East, Africa, and Europe, our logistics team is experienced in handling international shipping regulations and documentation.
Our products are trusted by provincial power companies across China and are a staple in international markets. We have established good business contacts globally, ensuring that "Shu Rong" brand products are top-of-mind for electrical engineers.
We sincerely welcome customers from home and abroad to discuss cooperation and work together for the prosperity and development of the electric power industry.
"Quality is the life of an enterprise, and science and technology are the soul." - This philosophy drives us to excel in every fuse we manufacture, from the smallest 10kV miniature link to the largest 36kV current-limiting fuse.
