Wenzhou Shuguang Fuse Co., Ltd., located in Yueqing, Zhejiang Province—the renowned electrical capital of China—stands as a premier power technology enterprise. We integrate professional research, high-end development, precision production, and global sales service under one roof.
The predecessor of our company, "Yueqing Shuguang Fuse Factory," was established in 1992. Over three decades, we have evolved from a local manufacturer into a leading WholesaleElectroFuse supplier known for engineering reliability and technical innovation.
The global shift toward "Smart Grids" has skyrocketed the demand for high-precision WholesaleElectroFuse components. Modern power systems require fuses that not only protect against overcurrent but also offer predictable performance in complex digital environments. Our high-voltage current-limiting fuses are engineered to meet these evolving requirements.
With the rise of Solar and Wind farms globally, there is a specialized need for fuses that can handle high DC voltages and fluctuating power cycles. Wenzhou Shuguang has developed dedicated fuse links for power capacitors and transformer protection specifically for the renewable sector, ensuring stable energy transmission across continents.
Electric vehicle (EV) infrastructure is the newest frontier. Procurement for high-voltage DC fuses used in charging stations and on-board battery systems is at an all-time high. Our EV Fuse Manufacturer division focuses on compact, fast-acting fuses that comply with international safety standards for the automotive industry.
As a leading China factory, we monitor these trends closely. The transition from traditional thermal protection to digital-ready electrical safety is at the core of our R&D strategy, making us a reliable partner for global infrastructure projects.
Wenzhou Shuguang is officially designated by the Ministry of Electric Power Industry to produce high-voltage fuses across all voltage levels. Our technical prowess is backed by rigorous testing at world-class laboratories.
Compliant with IEC60282-1, IEC60644, and IEC60470 for global interoperability.
Manufacturing excellence following DIN43625 and BS2692 technical specifications.
Meeting ANSI C37.42 requirements for the North American and international markets.
A complete and verified quality assurance system for every production batch.
Industrial buyers today look for more than just a product; they seek Reliability, Scalability, and Technical Support. Whether it's a utility provider in Europe or a manufacturing plant in Southeast Asia, our WholesaleElectroFuse solutions are applied in critical environments.
In high-voltage substations (12kV to 36kV), our current-limiting fuses protect expensive transformers and switchgear from the catastrophic effects of short circuits. Local power companies rely on our DIN Standard HRC fuses for their high breaking capacity and consistent arc quenching.
Heavy industries require robust protection. Our oil-immersed transformer fuses and polymeric insulators are designed to withstand harsh, corrosive environments, ensuring continuous operation in oil fields and mining sites across the Middle East and Africa.
The "Drop Out Fuse Cut Out" and "Lightning Arrester" lines are essential for overhead distribution lines in urban and rural areas. They provide an easily visible disconnection point and protect the network from atmospheric overvoltages.
Our "Shu Rong" brand has carved a niche in both domestic and international markets. Our products are exported to various provincial power companies within China, forming a nationwide sales network. Internationally, we have a strong presence in Southeast Asia, the Middle East, Africa, and Europe.
We adhere to the principle: "Development by science and technology, and survival by quality." We invite partners from across the globe to collaborate with us in driving the prosperity of the electric power industry.
