Wenzhou Shuguang Fuse Co., Ltd.
Located in Yueqing, Zhejiang Province, known as the electrical capital of China, Wenzhou Shuguang Fuse Co., Ltd. has evolved into a premier power technology enterprise. We integrate advanced research, development, production, and professional sales services.
Our roots trace back to the Yueqing Shuguang Fuse Factory established in 1992. With over three decades of deep industry experience, we have mastered the intricacies of high-voltage circuit protection, providing ODM and OEM services to some of the world's most demanding electrical infrastructure projects.
As the world shifts toward solar and wind power, current limiting fuses are critical for protecting DC/AC inverters and battery storage systems from transient overcurrents.
Global utility providers are demanding "intelligent" circuit protection. Our DIN standard HRC fuses are designed for seamless integration into modern smart-grid switchgear.
Rapid urban growth and the rise of Electric Vehicle charging stations require high-breaking capacity fuses that can handle higher voltage levels (up to 36kV) in compact footprints.
The global procurement landscape for electrical components has shifted. Procurement officers from Europe, the Middle East, and Southeast Asia increasingly seek Chinese ODM (Original Design Manufacturer) partners like Shuguang Fuse because of:
Our commitment to E-E-A-T principles is backed by hard data and official certifications. Wenzhou Shuguang Fuse is designated by the Ministry of Electric Power Industry to produce high-voltage fuses for various voltage levels.
Our products have successfully passed rigorous testing at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute. We strictly adhere to:
ANSI C37.42 | DIN 43625 | BS 2692 | IEC 60282-1 | IEC 60644 | IEC 60470 | GB 15166.2 | VDE 0636 | IS0 9001:2000
Our H.V. HRC fuses provide back-up protection for oil-immersed transformers, preventing catastrophic failures during internal faults.
Specialized Tail-wire recovery capacitor protection fuses ensure that individual unit failures do not escalate into entire bank outages.
Widely used in mining, heavy manufacturing, and oil/gas fields where reliable current limiting is required to protect expensive machinery.
The company continues to deepen and improve the quality management system. While vigorously developing new products, it has always attached importance to the process flow. High-quality raw materials and sophisticated testing equipment are the backing of our quality assurance system.
Our "Shu Rong" brand products have enjoyed a high reputation among domestic and foreign users. We offer customization for technical parameters such as rated current, melting characteristics, and physical dimensions to meet the unique requirements of localized power grids in Africa or Europe.
Our products are exported to various provincial power companies in China and across the globe. A complete sales network has been formed to serve Southeast Asia, the Middle East, Africa, and Europe.
We sincerely welcome customers from home and abroad to discuss cooperation. Let us work together for the prosperity and development of the electric power industry and create a brilliant future.
