Established in 1992 as "Yueqing Shuguang Fuse Factory," we have grown into a premier power technology enterprise. Located in Yueqing, the electrical capital of China, our company integrates research, development, production, sales, and service to provide comprehensive circuit protection solutions.
With over three decades of experience, we specialize in high-voltage capacitor fuses, current-limiting fuses, and expulsion fuse links that safeguard critical power infrastructure worldwide. Our brand "Shu Rong" is synonymous with reliability in the global electrical industry.
The global demand for high-quality capacitor fuses is surging as nations upgrade their aging power grids. High-voltage power capacitors are essential for power factor correction and voltage stability. Without robust protection from specialized fuses, capacitor bank failures can lead to catastrophic system-wide outages. We are at the forefront of this supply chain, providing critical components to utility companies across Europe, Asia, and Africa.
The industry is shifting towards "Smart Grid" compatibility and renewable energy integration. Wind and solar farms require high-performance fuses that can handle harmonic distortions and frequent switching operations. Our R&D team is focused on developing miniature, high-breaking capacity fuses that meet the evolving needs of the green energy revolution, ensuring that power remains clean and stable.
International procurement officers now prioritize "E-E-A-T" compliance—Expertise, Authoritativeness, and Trustworthiness. Buyers from the Middle East and Southeast Asia require products that strictly adhere to IEC 60282 and DIN standards. As a verified manufacturer, Wenzhou Shuguang Fuse Co., Ltd. provides full traceability and certified testing reports from top-tier institutes like Xi'an High-Voltage Electrical Apparatus Research Institute.
Our capacitor fuses are designed for diverse environments. In the scorching heat of Middle Eastern deserts, our fuses maintain thermal stability. In the humid coastal regions of Southeast Asia, our anti-corrosion coatings ensure longevity. From urban substations in London to industrial manufacturing plants in Vietnam, Shuguang products provide a "shield" for electrical systems, preventing overcurrent damage and minimizing downtime.
As a leading Chinese factory, we offer an unparalleled balance of cost-efficiency and technical excellence. Yueqing's mature industrial cluster allows us to source the highest quality raw materials—such as high-purity silver elements and reinforced ceramic casings—at competitive prices. Our vertical integration means we can offer custom OEM/ODM services with shorter lead times than Western competitors, without compromising on international safety standards.
Wenzhou Shuguang Fuse Co., Ltd. is designated by the Ministry of Electric Power Industry to produce a wide range of high-voltage components. Our products undergo rigorous testing at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.
Our commitment to "Development by science and technology" drives us to continuously improve our process flow. Using high-quality raw materials and sophisticated testing equipment, we ensure every "Shu Rong" brand product exceeds user expectations. We are capable of customizing products for specialized high-power test stations and laboratory environments.
We serve provincial power companies across China and export heavily to Southeast Asia, the Middle East, Africa, and Europe. Our sales network is one of the most comprehensive in the industry.
