Located in Yueqing, Zhejiang—the renowned "Electrical Capital of China"—Wenzhou Shuguang Fuse Co., Ltd. is a premier power technology enterprise. We seamlessly integrate R&D, production, sales, and service to provide world-class circuit protection solutions. Our journey began in 1992 as "Yueqing Shuguang Fuse Factory," and for over three decades, we have remained at the forefront of the electrical industry.
As a trusted China EvFuses Manufacturer & Supplier, we specialize in high-voltage fuses, current-limiting fuses, and specialized protection for transformers, capacitors, and modern electric vehicle infrastructure. Our deep-rooted experience ensures that every product we manufacture meets the rigorous demands of modern power grids.
The global transition toward sustainable energy has catalyzed an unprecedented demand for reliable EvFuses and high-voltage circuit breakers. As industries shift from internal combustion to electric powertrains, the complexity of electrical protection has increased exponentially. Today's commercial and industrial sectors require fuses that can handle high DC voltages, rapid thermal cycling, and intense vibration environments.
The rise of 800V EV architectures demands fuses with higher breaking capacities and smaller footprints. Integration of smart monitoring is the next frontier.
International procurement managers are increasingly looking toward China for a balance of cost-efficiency, rapid prototyping, and massive scale.
From Nordic wind farms to tropical solar arrays, our fuses are designed to withstand extreme localized environmental conditions globally.
In the industrial sector, the expansion of EV charging networks (EVSE) requires robust protection at the distribution level. Our High Voltage Current-Limiting Fuses are essential for protecting the sensitive power electronics within fast-charging stations, ensuring that any fault is isolated within milliseconds to prevent catastrophic equipment failure.
Our authority in the field is backed by strict adherence to international protocols. Wenzhou Shuguang Fuse products are designated by the Ministry of Electric Power Industry for high-voltage applications. Every component undergoes rigorous testing at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute.
Our performance tests qualify under: IEC60282-1, DIN43625, BS2692, ANSI C37.42, and VDE0636. This ensures our products are ready for deployment in any jurisdiction.
Certified under ISO9001:2000, our manufacturing process involves high-quality raw materials and sophisticated testing equipment to ensure zero-defect output.
From Grid Stability to Electric Mobility
Power Distribution: Ensuring safety in provincial power grids and urban substations.
Renewable Energy: Protecting solar inverters and wind turbine transformers.
Electric Vehicles: Specialized EvFuses for battery packs and charging piles.
Industrial UPS: Fault protection for critical data centers and hospital power units.
Choosing Wenzhou Shuguang Fuse Co., Ltd. as your strategic partner offers several distinct advantages in the competitive global market:
We rapidly prototype new fuse designs to meet the evolving specs of the EV industry, reducing your time-to-market.
Located in the heart of China's electrical hub, we have direct access to high-purity copper, silver, and technical ceramics.
Our scaled manufacturing processes allow us to offer premium protection at prices that support your project's ROI.
Our "Shu Rong" brand is synonymous with durability. In the power industry, where a single fuse failure can lead to millions in damages, our 99.9% reliability rate is why we are the preferred supplier for Southeast Asia, the Middle East, and Europe.
Precision Engineered for Maximum Safety
The role of a China EvFuses Manufacturer extends beyond simple production; it involves a deep understanding of electrical physics and material science. At Wenzhou Shuguang Fuse, we continuously refine the process flow and raw material selection. High-purity quartz sand with controlled grain size is utilized as the arc-extinguishing medium, ensuring that high-voltage arcs are quenched within a fraction of a cycle.
Every electrical grid has its nuances. European markets often demand DIN Standard fuses, while American markets may require specialized ANSI ratings. Our facility is uniquely equipped to customize performance indicators—such as I²t (let-through energy) values and melting characteristics—to meet specific user needs. Whether you are an OEM for EV battery packs or a utility provider in the Middle East, our team can tailor solutions that align with your technical blueprints.
We believe in "Development by science and technology, and survival by quality." As we look toward 2030, our R&D is focused on eco-friendly materials and "Smart Fuses" that can communicate their status to a central management system. This technological leap will reduce maintenance costs and downtime for industrial operators worldwide. By integrating AI-driven design tools, we are reducing waste and increasing the precision of our high-voltage current-limiting series.
We sincerely welcome customers from home and abroad to discuss cooperation. Join hands with Wenzhou Shuguang Fuse Co., Ltd.—your reliable partner for high-voltage protection and global EvFuse supply. Together, let’s create a safer, more efficient future for the power industry.
