Industry-standard fuses engineered for extreme environments.
Understanding the vital role of British Standard fuses in modern engineering.
The BS88 standard (now largely harmonized with IEC 60269) represents the pinnacle of low-voltage fuse engineering. Originating from British industrial specifications, BS88 fuses are globally recognized for their unmatched reliability, high breaking capacity (typically up to 80kA), and precise time-current characteristics.
Today, these fuses are essential in Commonwealth nations and beyond, protecting industrial motor circuits, power distribution boards, and sensitive electronic equipment. As a leading China BS88 fuse supplier, we ensure that every unit produced in our Yueqing facility mirrors the rigorous safety demands of international power grids.
Established in 1992 as "Yueqing Shuguang Fuse Factory," our company is located in Yueqing, Zhejiang Province—widely known as the Electrical Capital of China. We have evolved into a sophisticated power technology enterprise that integrates R&D, production, sales, and global service.
With over three decades of experience, we have become a designated producer for the Ministry of Electric Power Industry. Our expertise spans high-voltage current-limiting fuses, power capacitor protection, zinc oxide arresters, drop-out fuses, and high-voltage insulators.
We believe in "Development by science and technology, and survival by quality." This philosophy has allowed us to serve both the domestic Chinese grid and international partners with equal excellence.
Adapting to the New Energy Revolution and Smart Infrastructure.
The global shift toward Solar (PV) and Wind energy requires specialized DC fuses and high-voltage protection. Our R&D department is actively developing fuses that can handle the unique oscillating currents of renewable inverters.
The rise of EV charging stations demands high-speed fuses (aR type) to protect semiconductor components. We provide wholesale EV fuses designed to handle rapid thermal cycles and high vibration.
Data centers and modern hospitals require "no-fail" electrical systems. BS88 fuses provide the selectivity needed to ensure that a local fault does not trigger a widespread blackout in critical facilities.
As factories move toward Industry 4.0, the protection of motor control centers (MCC) becomes vital. Our J-Slotted and DIN standard fuses offer the precision required for robotic assembly lines.
Aging grids in North America and Europe are being replaced with medium-voltage current-limiting solutions. Our products comply with IEC60282, providing a bridge between legacy systems and future tech.
Global procurement teams now prioritize ESG and safety certifications. By strictly following VDE, BS, and IEC standards, we simplify the import process for global distributors.
Meeting and exceeding the most stringent international technical conditions.
Our products have passed rigorous evaluations at the Electric Power Research Institute, the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center, and the Xi'an High-voltage Electrical Apparatus Research Institute. We take pride in ensuring 100% pass rates for all performance tests.
Versatile solutions for diverse industrial environments worldwide.
In the rugged mining sectors of Australia and Africa, our expulsion fuses and high-voltage HRC fuses protect heavy machinery from unpredictable surges, ensuring operational continuity in harsh climates.
Our H.V. HRC fuses specifically designed for oil-immersed transformers (Back-up protection) are widely used by power utilities in Southeast Asia to prevent catastrophic transformer failures.
In densely populated European cities, our DIN Standard fuses fit seamlessly into compact sub-stations, providing low-noise and zero-emission circuit breaking in residential zones.
The Shuguang Advantage: Quality, Efficiency, and Reliability.
Located in Yueqing, we have direct access to the world's most efficient electrical component supply chain. This means shorter lead times and highly competitive pricing for bulk orders.
Beyond our standard catalog, we specialize in OEM/ODM production. Whether it's a specific "Shu Rong" brand requirement or a unique current-limiting characteristic, our engineers are ready to deliver.
Every fuse undergoes multi-stage testing. From raw material inspection to the high-power test station, we ensure that no product leaves our factory without meeting IEC standards.
From low voltage RT18 to high voltage RN series.
Whether you are looking for wholesale BS88 fuses, high-voltage current-limiting solutions, or custom OEM manufacturing, Wenzhou Shuguang Fuse Co., Ltd. is your authoritative partner in China.
