Established in 1992 as the "Yueqing Shuguang Fuse Factory," our journey began in the heart of China's electrical capital—Yueqing, Zhejiang Province. Today, Wenzhou Shuguang Fuse Co., Ltd. has evolved into a premier power technology enterprise that seamlessly integrates R&D, production, global sales, and specialized technical services.
Our expertise spans over three decades, focusing on high-voltage circuit protection. As a designated manufacturer for the Ministry of Electric Power Industry, we have pioneered the development of high-voltage current-limiting fuses, capacitor protection systems, and zinc oxide arresters that form the backbone of modern power grids.
The global electricity fuse market is witnessing an unprecedented surge, driven by the rapid expansion of Smart Grids and the global transition to renewable energy. Industrial facilities worldwide are upgrading their protection systems to handle higher voltage loads and more complex distribution networks.
As a leading China OEM manufacturer, we provide tailored solutions for international engineering firms. Whether it's specific voltage ratings or unique mechanical dimensions for legacy system retrofitting, our production line is optimized for flexibility and precision.
Modern procurement demands go beyond just "buying a component." Global enterprises now seek partners who can provide compliance, sustainability, and technical reliability.

With the rise of Electric Vehicles, the demand for high-speed EV fuses is skyrocketing. Our EV-series fuses are designed to handle the high DC voltages and rapid thermal cycling found in modern charging infrastructure and battery packs.
Solar and wind farms require specialized protection against over-currents in variable load environments. Our DIN standard and HRC fuses are optimized for PV inverters and offshore wind turbine transformers.
Metropolitan power grids are moving toward compact, high-reliability components. Our drop-out fuses and polymeric insulators provide long-lasting protection with minimal maintenance requirements in polluted or coastal environments.
Authoritativeness is built on rigorous testing. Our products have successfully passed evaluations at the Electric Power Research Institute and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.
We comply with a vast array of international standards to ensure seamless integration into any global project:
Our ISO 9001:2000 quality assurance system ensures that every "Shu Rong" brand product leaving our factory is ready for the world's most demanding environments.
In recent years, our investment in AI-driven manufacturing and sophisticated testing equipment has set us apart. While vigorously developing new products, we prioritize the process flow. Using high-quality raw materials is not just a choice; it's our backing for a zero-defect quality assurance system.
Customization Capability: We can produce bespoke high-voltage fuses based on specific user requirements—whether it is for extreme temperature operation or specialized mounting configurations.
