Established in 1992 as the "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a premier power technology enterprise. Located in Yueqing, Zhejiang—famously known as the Electrical Capital of China—our company integrates advanced research, development, production, and global sales services.
As a leading China OEM British Standard Fuses Supplier, we have spent over three decades perfecting the art of electrical protection. Our commitment to quality is rooted in our history of serving the Ministry of Electric Power Industry, providing critical components that safeguard national and international power grids.
British Standard (BS) fuses, particularly those conforming to BS 2692 and BS 88, remain the cornerstone of electrical safety across the UK, Australia, India, and Middle Eastern nations. Their unique physical dimensions—such as the J-slotted 82mm and 92mm configurations—make them irreplaceable in historical and modern infrastructure alike.
The global shift toward green energy has revolutionized fuse demand. Modern OEM British Standard Fuses are now engineered to handle the specific transient overcurrents of solar PV inverters and wind turbine controllers. Our factory is at the forefront of this trend, producing high-voltage HRC fuses that meet the rigorous IEC 60282-1 standards.
Electric vehicle (EV) infrastructure requires specialized protection. Our Wholesale EV Fuse series is designed for DC high-voltage applications, providing ultra-fast breaking capacity to protect lithium battery packs and charging stations from catastrophic failure.

This commitment to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) ensures that every China Low Voltage Fuse or High Voltage Current-Limiting Fuse leaving our factory is capable of withstanding the most extreme industrial conditions.
Global procurement managers are increasingly looking for partners who offer more than just a product. They require stability, customization, and scalability. As a British Standard Fuses Factory in China, we provide:
Protection of oil-immersed transformers and switchgear using HRC current-limiting fuses.
Safeguarding heavy machinery and voltage transformers in automated production lines.
Specialized expulsion fuse links and tail wire recovery fuses for capacitor bank protection.
Our company adheres to the principle of "Development by science and technology, and survival by quality." We have built a complete sales network across provincial power companies in China and exported our Shu Rong brand to Southeast Asia, the Middle East, Africa, and Europe.
In the landscape of modern electrical engineering, the fuse remains the ultimate fail-safe. While digital breakers have their place, the physical disconnection provided by a high-quality HRC Fuse Link is the only guaranteed way to prevent catastrophic equipment damage during a short circuit. As a China British Standard Fuse Manufacturer, we understand that our products are the last line of defense for multi-million dollar investments.
Our research focuses on the synchronization of traditional BS 2692 dimensions with modern material science. For instance, our Oil Fuse-Link Medium Voltage 63A units are engineered with specialized ceramic bodies that withstand thermal shock and internal pressure, a critical requirement for oil-immersed transformer protection. Furthermore, our J Slotted Fuse designs (available in both 82mm and 92mm) ensure compatibility with existing utility fuse pillars, making us the preferred choice for infrastructure retrofit projects globally.
Whether you are a wholesale distributor looking for a reliable China High Voltage Fuse Factory or a utility engineer requiring specific technical compliance, Wenzhou Shuguang Fuse Co., Ltd. offers the expertise and production capacity to meet your demands. We sincerely welcome customers from home and abroad to discuss cooperation and work together for the prosperity and development of the electric power industry.
