The global shift toward Electric Vehicles (EVs) has fundamentally redefined the requirements for circuit protection. Unlike traditional combustion engines, EV platforms rely on high-voltage DC systems reaching up to 800V or 1000V. This requires fuses with exceptional breaking capacity and precision, ensuring the safety of the Battery Management System (BMS) and power electronics.
In an era of supply chain volatility, sourcing from a vertically integrated "China OEM Ev Fuses Factory" provides unparalleled stability. Wenzhou Shuguang Fuse Co., Ltd. combines raw material sourcing, automated precision assembly, and rigorous lab testing to mitigate global logistics risks and provide competitive lead times.
A fuse is more than a sacrificial component; it is the final line of defense. Advanced OEM fuses utilize high-purity silver elements and high-strength alumina ceramic bodies to withstand extreme thermal cycles and mechanical shocks prevalent in automotive and industrial environments.
Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, the electrical capital of China. We are 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 evolved from a local manufacturer into a global powerhouse in the fuse industry. Our focus on Ev Fuses and high-voltage protection stems from a deep-rooted commitment to electrical safety and technological innovation. Today, as an industry-leading OEM/ODM partner, we support the world's most demanding infrastructure projects.
Our manufacturing facility in Yueqing leverages Industry 4.0 principles, integrating automated stamping, laser welding, and real-time quality monitoring. This digital transformation ensures that every "China EV Fuse" meets the exact tolerances required for modern power electronics. Our supply chain resilience is built on localized clusters, allowing us to source specialized ceramics and metallurgy within a 50km radius, ensuring efficiency that Western competitors cannot match.
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 through the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and Xi'an High-voltage Electrical Apparatus Research Institute.
Our technical performance meets and exceeds: ANSIC37,42, DIN43625, BS2692, IEC282-2, IEC60644, IEC60470, IEC60282-1, IEC269-2, GB15166.1, GB15166.2, DL/T640-1997, and VDE0636. This comprehensive compliance profile makes Shuguang the preferred choice for EPC contractors and OEM manufacturers worldwide.
Protection for Battery Energy Storage Systems (BESS) and electric vehicle drivetrains. Our fuses handle the high inrush currents and rapid discharge cycles unique to lithium-ion technology.
Enhancing urban power distribution with current-limiting HRC fuses. These are vital for isolating faults in densely populated metropolitan grids to prevent cascading failures.
Solar PV inverters and Wind turbine transformer protection. Our fuses are optimized for the variable load profiles and environmental stressors of outdoor renewable plants.
High-voltage protection for large-scale industrial motors and manufacturing plants, ensuring operational uptime and worker safety in heavy industry settings.
Our products are exported to various provincial power companies in China and throughout the global market. We have established robust business contacts across Southeast Asia, the Middle East, Africa, and Europe. We welcome partners from around the world to collaborate and create a brilliant future for the global electric power industry.
