Engineered for excellence, trusted by power grids worldwide.
Located in Yueqing, Zhejiang Province—the electrical capital of China—Wenzhou Shuguang Fuse Co., Ltd. is a power technology enterprise integrating R&D, production, sales, and service. Our history traces back to the "Yueqing Shuguang Fuse Factory," where we began a mission to redefine high-voltage protection.
With over three decades of expertise, we have evolved into a major ODM/OEM powerhouse. We are designated by the Ministry of Electric Power Industry to manufacture critical high-voltage components. Our commitment to "Development by science and technology, and survival by quality" drives every fuse we produce.
How ODMBigFuses are shaping the future of industrial power protection.
The global demand for ODMBigFuses is surging as nations upgrade aging power grids. From the rapid industrialization in Southeast Asia to the grid modernization projects in Europe and North America, high-capacity circuit protection is no longer optional—it is a critical safety requirement for urban and industrial infrastructure.
With the rise of solar farms and wind power installations, specialized fuses for power capacitors and transformers are essential. High-voltage HRC (High Rupturing Capacity) fuses are increasingly used to protect sensitive green energy converters from current surges, ensuring stable distribution of clean energy.
Electric Vehicle (EV) infrastructure requires robust protection. Our EV Fuses are specifically designed to handle the high DC currents found in fast-charging stations and large-scale battery storage systems, providing a safe bridge between power source and vehicle.
Meeting and exceeding international standards for absolute reliability.
Our products have passed rigorous evaluations at the High-Power Test Station of the Electric Power Research Institute and the Xi'an High-Voltage Electrical Apparatus Research Institute. Every performance test is qualified under the strictest conditions.
The competitive edge of a top-tier China ODMBigFuses factory.
We combine high-quality raw materials with sophisticated testing equipment. Our factory in Yueqing utilizes automated production lines to ensure precision in every component, from fuse links to expulsion tubes.
As a specialized manufacturer, we don't just sell off-the-shelf. We provide tailored solutions. Whether you need specific voltage levels (12kV, 24kV, 36kV) or unique physical dimensions, our R&D team delivers.
Being at the heart of China’s electrical capital gives us unparalleled access to logistics and components, allowing us to offer shorter lead times and highly competitive pricing for bulk global procurement.
Our fuses are the silent guardians of infrastructure worldwide.
From oil-immersed transformers to modern substations, "Shu Rong" brand products have built a high reputation among domestic and international users. Our fuses are widely applied in:
