Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, the world-renowned "Electrical Capital of China." We are a specialized power technology enterprise integrating research, development, production, and global service.
Our journey began in 1992 as "Yueqing Shuguang Fuse Factory." For over three decades, we have evolved into a leading authority in the high-voltage fuse industry. Our focus is on the critical safety of power lines, ensuring that electrical grids across the globe operate with maximum reliability and minimal downtime.
In today's interconnected world, the stability of power lines is a matter of national security and economic prosperity. As nations modernize their aging electrical grids and integrate renewable energy sources like wind and solar, the demand for high-performance protection devices has reached an all-time high.
The European market, and increasingly the Middle East and Southeast Asia, demand CE Certification. This ensures that fuses used on power lines meet strict health, safety, and environmental protection standards. Our products are engineered to exceed these global benchmarks.
Modern power grids require fuses that can handle high-frequency fluctuations and rapid fault isolation. We are at the forefront of this evolution, developing current-limiting fuses that protect sensitive transformer and capacitor components from catastrophic failure.
The global shift toward EV charging infrastructure and green energy storage has created a new frontier for high-voltage protection. Our CE-certified fuses provide the reliable breaking capacity needed for high-DC voltage environments.
Our commitment to quality is backed by the most rigorous testing institutions in the industry. Wenzhou Shuguang Fuse Co., Ltd. is designated by the Ministry of Electric Power Industry to produce high-voltage fuses across various voltage levels.
Our products have successfully passed testing at:
We strictly adhere to ISO9001:2000 and our technical performance meets or exceeds: ANSI C37.42, DIN 43625, BS 2692, IEC 60282-1, IEC 60644, VDE 0636, and national GB15166 standards.
International industrial buyers from Southeast Asia, the Middle East, Africa, and Europe look for more than just a product; they look for a reliable supply chain partner. As a dedicated China manufacturer, we bridge the gap between high-end engineering and cost-effective production.
Whether it's protecting a rural substation in Southeast Asia or a high-density industrial park in Europe, our fuses are designed for diverse environments, including high humidity, extreme temperatures, and coastal salt spray conditions.
We understand that procurement requirements vary. We offer customization of high-voltage current-limiting fuses and expulsion fuse links to match specific transformer protections and voltage transformer (PT) protection needs.
Operating out of Yueqing gives us access to a world-class raw material ecosystem. This ensures we use high-quality ceramics, silver elements, and precision-engineered housings while maintaining competitive factory pricing.
In recent years, our company has developed rapidly, and our "Shu Rong" brand has enjoyed a high reputation among domestic and foreign users. Our economic and social benefits have improved significantly through a continuous deepening of our quality management system.
Technological Edge:
Our products serve as the "silent guardians" of the electrical world, from provincial power grids in China to massive infrastructure projects abroad.
Ensuring that high-voltage transformers are shielded from overcurrent and short-circuit faults.
Reliable protection for large-scale manufacturing plants and chemical processing facilities.
Drop-out fuses and current-limiting links for city-wide electrical reliability.
A complete sales network has been formed throughout China, establishing strong business contacts with provincial power companies. Beyond domestic borders, our new high-voltage fuses are exported to Southeast Asia, the Middle East, Africa, Europe, and other regions. We rank among the top of the industry in sales volume and user satisfaction.
