Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a cornerstone of China's electrical capital in Yueqing, Zhejiang Province. As a premier power technology enterprise, we integrate research, development, high-precision production, and global sales service.
With over three decades of unmatched expertise in CustomFuseVoltage systems, we specialize in high-voltage fuses, zinc oxide arresters, and insulators. Our commitment to grid safety and reliability has positioned us as a trusted partner for national power grids and international industrial giants alike.
The global electrical landscape is undergoing a radical shift toward renewable energy integration and smart grid modernization. In this context, CustomFuseVoltage components have become critical. From medium-voltage distribution networks to high-voltage industrial substations, the demand for precise current-limiting fuses is at an all-time high.
Industry trends indicate a significant move toward miniaturization and environmental resilience. Modern power systems in Europe and North America now require fuses that can withstand extreme weather while providing faster response times to protect sensitive silicon-based power electronics. Our factory stays ahead of these trends by utilizing high-quality raw materials and sophisticated testing equipment, ensuring every CustomFuseVoltage unit meets the evolving needs of global procurement agents.
Double-digit growth in the EV and Renewable sectors driving demand for specialized DC and HV fuses.
Adoption of digital monitoring within fuse holders to track load stress and predictive maintenance.
Shift towards polymeric and eco-friendly insulating materials for better lifecycle management.
Our products are designated by the Ministry of Electric Power Industry for high-voltage applications. We take pride in our rigorous testing at national-level laboratories.
