In the current industrial landscape, Utility Fuses are the cornerstone of electrical grid stability. As nations transition toward smart grids and renewable energy integration, the demand for high-reliability circuit protection has surged across Europe, Southeast Asia, and the Middle East.
The industry is moving toward Miniaturization and Digitalization. Today’s procurement demands focus on fuses that can withstand extreme environmental conditions while conforming to rigorous international standards like IEC 60282 and DIN 43625.
Global enterprises now prioritize ODM (Original Design Manufacturing) capabilities. Suppliers must offer tailored solutions for transformer protection, capacitor banks, and the rapidly growing EV infrastructure market.
Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, the electrical capital of China. As a premier power technology enterprise, we integrate research, development, production, sales, and service under one roof. The predecessor of Wenzhou Shuguang Fuse Co., Ltd. was "Yueqing Shuguang Fuse Factory" established in 1992.
With over three decades of technical accumulation, we have evolved from a local workshop into a global powerhouse in high-voltage protection. Our location in Yueqing provides us with a unique competitive edge, granting us access to the world's most comprehensive electrical supply chain, allowing for rapid ODM prototyping and large-scale manufacturing efficiency.
Our commitment to quality is backed by rigorous testing. 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.
The products have passed the high-power test station of the Electric Power Research Institute of the Ministry of Electric Power, the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center, the Xi'an High-voltage Electrical Apparatus Research Institute, and the High-Voltage Electrical Apparatus Laboratory. All performance tests are qualified.
Compliance Matrix: The highest technical performance meets the ANSIC37.42, DIN43625, BS2692, IEC282-2-1995, IEC60644, IEC60470, IEC60282-1, IEC269-2 and GB15166.1, GB15166.2, GB15166.5, GB13593, DL/T640-1997, VDE0636 standards. Our quality assurance system is complete, having passed ISO9001: 2000 quality system certification.
Our products are exported to various provincial power companies in China, forming a complete domestic network. Beyond borders, our high-voltage current-limiting fuses are exported to Southeast Asia, the Middle East, Africa, Europe and other regions. We rank among the top in the industry for domestic and international sales.
Our flagship "Shu Rong" brand enjoys a high reputation globally. In recent years, our economic and social benefits have improved significantly as we continue to deepen our quality management. We prioritize high-quality raw materials and sophisticated testing equipment as the backbone of our assurance system.
As a China-based factory, we offer unmatched customization. Whether it is a tail wire recovery capacitor fuse or a specialized EV fuse, we can produce according to specific user needs at any time, ensuring that local application scenarios are met with precision.
