Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a global titan in power technology. Located in Yueqing, Zhejiang Province—the world-renowned "Electrical Capital of China"—our facility integrates advanced R&D, high-precision production, and a robust sales network.
With over three decades of engineering expertise, we specialize in high-voltage fuses, arresters, and insulators. As a recognized China OEM Standard Fuses Manufacturer, we don't just supply products; we provide critical safety components that protect national grids, industrial plants, and renewable energy systems worldwide.
The global electrical fuse market is undergoing a seismic shift. As the world transitions toward Smart Grids and Renewable Energy, the demand for reliable circuit protection has never been higher. Standard fuses, particularly High Voltage HRC (High Rupturing Capacity) types, are now the backbone of infrastructure resilience in Europe, Southeast Asia, and North America.
Expansion in urban power grids and the electrification of industrial processes are driving 5% annual growth in the fuse sector. Modern industries require fuses that can handle higher fault currents with minimal downtime.
The rise of Electric Vehicles (EVs) and Solar Photovoltaic systems has created a niche for specialized 1500V DC fuses and customized EV fuse links. We are at the forefront of this technological shift.
Developing nations in Africa and the Middle East are investing heavily in new power substations, where Drop Out Fuse Cutouts and Porcelain insulators are essential for rural electrification.
Today’s global buyers—from utility companies to large-scale electrical contractors—prioritize three things: Compliance, Customization, and Supply Chain Speed. Global enterprises no longer just look for a part; they look for a partner who understands IEC 60282-1 and DIN 43625 standards and can provide OEM solutions that fit specific regional voltage requirements.
Wenzhou Shuguang Fuse Co., Ltd. is officially designated by the Ministry of Electric Power Industry. Our products have undergone rigorous validation at the Xi'an High-Voltage Electrical Apparatus Research Institute and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center. We ensure 100% compliance with international benchmarks including:
ANSI C37.42 | DIN 43625 | BS 2692 | IEC 60282-1 | IEC 60644 | IEC 60470 | GB 15166
Our fuses are engineered for diverse environments, ensuring protection where it matters most:
Based in Yueqing, we have immediate access to raw materials and precision components, allowing us to offer shorter lead times than Western competitors without compromising on quality.
Our engineering team can customize fuse links (size, ampacity, speed) based on unique CAD designs. We bridge the gap between "standard" and "bespoke" power protection.
The "Shu Rong" brand is synonymous with durability. Our domestic sales rank at the top of the industry, and we export to Southeast Asia, Europe, and Africa with zero-failure records.
We adhere to the principle: "Development by science and technology, and survival by quality." As the world moves toward 2030 sustainability goals, our factory is investing in eco-friendly manufacturing processes and silver-plated contact technology to reduce energy loss in fuse operations.
Join hands with a technical leader that understands the heartbeat of the global power grid. From 1992 to today, our mission remains unchanged: to provide the most reliable, high-performance power fuses for a safer, more electrified world.
