In the modern electrical infrastructure, Expulsion Fuses remain a cornerstone for overcurrent protection in distribution systems. These devices are critical for isolating faulted sections of the grid, preventing widespread blackouts and protecting expensive assets like transformers and capacitor banks. As a leading China CE Certification Expulsion Fuses Manufacturer, we recognize the growing global demand for high-reliability electrical components.
Globally, the expulsion fuse market is driven by the expansion of power distribution networks in developing nations and the aging infrastructure replacement in developed regions. From North American utilities to Southeast Asian industrial parks, the need for CE-certified, cost-effective, and durable expulsion fuses is at an all-time high.
The industry is shifting toward "Smart Grid" compatibility and environmental sustainability. Modern expulsion fuses are now designed with non-corrosive materials and enhanced arc-extinguishing capabilities. We integrate AI-assisted manufacturing processes to ensure every unit meets precise tolerance levels required for high-speed interruption.
International buyers are increasingly looking for "One-Stop" factories in China that can handle complex certifications. Reliability and lead time are the primary factors. Our factory in Yueqing addresses these by offering a streamlined supply chain and rigorous testing compliance.
Wenzhou Shuguang Fuse Co., Ltd.
Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, the electrical capital of China. It is a power technology enterprise integrating research, development, production, sales and service. The predecessor of Wenzhou Shuguang Fuse Co., Ltd. was "Yueqing Shuguang Fuse Factory" established in 1992.
For over three decades, we have dedicated ourselves to the mastery of electrical protection. Our evolution from a local factory to a globally recognized manufacturer is built on a foundation of quality and continuous technological innovation.
It is designated by the Ministry of Electric Power Industry to produce high-voltage fuses of various voltage levels, high-voltage current-limiting fuses, high-voltage fuses for power capacitors, voltage transformer protection fuses, zinc oxide arresters, drop-out fuses, high-voltage insulators, etc.
All performance tests are qualified by the Electric Power Research Institute, the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center, and the Xi'an High-voltage Electrical Apparatus Research Institute.
Our products meet international standards including: ANSI C37.42, DIN 43625, BS 2692, IEC 60282, IEC 60644, VDE 0636, and GB 15166.




In regions like Southeast Asia and Africa, expulsion fuses are vital for overhead distribution lines. Our fuses are engineered to withstand extreme humidity and temperature fluctuations, ensuring consistent performance in tropical climates.
Mining operations and heavy manufacturing require robust fault isolation. Our high-voltage current-limiting fuses provide the precision needed to protect localized transformers from massive surge currents.
As solar and wind farms expand, the need for specialized capacitor protection fuses has grown. Our products assist in stabilizing the reactive power compensation systems essential for modern green energy grids.
In recent years, Wenzhou Shuguang Fuse Co., Ltd. has developed rapidly, improving both economic and social benefits. We continuously deepen our quality management system, never compromising on long-term development. While vigorously developing new products, we maintain a strict focus on the process flow.
High-quality raw materials and sophisticated testing equipment are the backbone of our quality assurance system. "Shu Rong" brand products have enjoyed a high reputation among domestic and foreign users. We offer customization to meet specific user needs, ensuring that whether it's a standard DIN fuse or a specialized HV fuse, the performance is unmatched.
