The global demand for ODM motor fuses has reached an all-time high, driven by the rapid expansion of industrial automation and the Electric Vehicle (EV) revolution. As high-voltage motors become the heart of modern manufacturing, the need for precise circuit protection is paramount. Our factory bridges the gap between high-end technical requirements and scalable production.
Current trends emphasize "Smart Protection" and miniaturization. Modern motor fuses are no longer just passive components; they are engineered for specific thermal response profiles. With the integration of renewable energy grids, fuses must now handle variable loads while maintaining strict compliance with international safety standards like IEC 60282 and DIN 43625.
Global procurement teams are shifting away from off-the-shelf components toward specialized ODM (Original Design Manufacturing) partnerships. This allows for customized voltage levels and clearing times tailored to specific industrial machinery, ensuring maximum uptime and safety for multi-million dollar equipment investments.
Located in Yueqing, Zhejiang Province—the renowned Electrical Capital of China—Wenzhou Shuguang Fuse Co., Ltd. stands as a beacon of power technology excellence. Established in 1992 as "Yueqing Shuguang Fuse Factory," we have spent over 30 years perfecting the art and science of circuit protection.
We are a comprehensive power technology enterprise integrating research, development, production, sales, and service. Our legacy is built on the "Shu Rong" brand, which has earned a prestigious reputation among domestic and international users for reliability and technological innovation.
We are designated by the Ministry of Electric Power Industry to produce high-voltage fuses across various voltage levels. Our products undergo rigorous testing at the highest-power test stations in the nation, including the Electric Power Research Institute and the Xi'an High-voltage Electrical Apparatus Research Institute.
Standards Compliance:
Based in Yueqing, we leverage the world's most sophisticated electrical supply chain. This proximity allows us to source the highest quality raw materials—from high-purity silver elements to aerospace-grade ceramic bodies—at competitive speeds.
Our ODM capabilities mean we don't just sell fuses; we engineer solutions. Whether it's unique medium voltage levels (12kV, 24kV, 36kV) or specific current-limiting requirements for oil-immersed transformers, our lab can prototype and test according to your local requirements.
We have established a complete sales network globally, exporting to Southeast Asia, the Middle East, Africa, and Europe. Our logistics experience ensures that high-voltage current-limiting fuses reach your industrial site with all certifications intact.
Our fuses are utilized across critical infrastructure and high-tech sectors worldwide.
Protecting voltage transformers and power capacitors against short-circuit faults in provincial power grids.
Essential protection for EV charging stations and solar farm medium-voltage inverters.
Specialized motor fuses for mining, oil pumping, and large-scale water treatment facilities.
HRC fuses designed for oil-immersed transformer back-up protection, ensuring stability in extreme environments.
