Wenzhou Shuguang Fuse Co., Ltd. is a powerhouse in the electrical technology sector, located in Yueqing, Zhejiang—the renowned "Electrical Capital of China." Established in 1992 as the "Yueqing Shuguang Fuse Factory," we have grown over three decades into a leading power technology enterprise that integrates R&D, production, sales, and service.
Our commitment to excellence has earned us the designation by the Ministry of Electric Power Industry to produce specialized high-voltage fuses, current-limiting fuses, and power capacitor protection devices. By leveraging our deep industry experience, we ensure that every component manufactured in our facility meets the highest global standards of safety and efficiency.
The global demand for high current fuses is skyrocketing as nations modernize their power grids. From smart cities in Europe to rural electrification in Africa, reliable fuse technology is the backbone of modern energy distribution.
As the world shifts toward Solar and Wind energy, the need for specialized high-voltage protection increases. High current fuses are essential for protecting large-scale battery storage and inverter systems.
The rapid expansion of Electric Vehicle (EV) infrastructure requires robust circuit protection. Our specialized EV fuses are designed to handle the unique thermal and electrical demands of modern charging stations.
As a premier China OEM High Current Fuses Supplier, we recognize that the industry is moving toward "Smart Protection." Modern power systems demand fuses that are not only reliable in breaking high-energy faults but also compatible with automated monitoring systems. The global market is currently characterized by a shift from simple thermal protection to complex, multi-standard compliant devices that can withstand extreme environmental conditions.
Miniaturization & Higher Performance: As electrical panels become more compact, the demand for smaller fuse footprints with higher breaking capacities is a key R&D focus. We are continuously optimizing our internal element designs to provide maximum protection in minimal space.
Standardization & Interchangeability: Global procurement managers are increasingly seeking products that meet multiple international standards (DIN, ANSI, IEC, BS) simultaneously to simplify inventory management. Our products are engineered to bridge these standard gaps.
Material Innovation: The use of advanced ceramics and specialized polymer insulators is enhancing the durability of high current fuses, allowing them to operate in harsher climates, from deserts to coastal regions with high salt spray.
Our commitment to quality is backed by rigorous testing and international compliance.
Our technical performance meets and exceeds ANSIC37,42, DIN43625, BS2692, IEC282, IEC60644, IEC60470, IEC60282-1, and many other global standards. All products have passed stringent evaluations at the High-power Test Station of the Electric Power Research Institute and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.
Located in the heart of the electrical industrial cluster, we have immediate access to high-quality raw materials and specialized manufacturing equipment, ensuring shorter lead times for global orders.
Our engineering team can customize fuse parameters and mechanical fittings based on specific local grid requirements, providing true OEM/ODM flexibility for international brands.
Unlike standard traders, our factory employs 100% inspection protocols using sophisticated testing equipment, ensuring that every batch meets the reliability expected for critical infrastructure.
Our high current fuses are deployed in diverse environments across Southeast Asia, the Middle East, Africa, and Europe. In tropical regions, our polymer-insulated fuses resist humidity and corrosion. In industrial hubs, our HRC current-limiting fuses protect transformers from catastrophic failures, while in modern urban grids, our drop-out fuses provide visible circuit isolation for maintenance safety.
The company adheres to the principle of "Development by science and technology, and survival by quality." As a global China OEM High Current Fuses Supplier, we sincerely welcome customers from home and abroad to discuss cooperation and work together for the prosperity and development of the electric power industry.
Whether you are looking for drop-out fuses, high-voltage current-limiting fuses, or zinc oxide arresters, Wenzhou Shuguang Fuse Co., Ltd. provides the technical backing and reliable quality assurance your projects demand. Join our global sales network and create a brilliant future with the "Shu Rong" brand products.
