The global electrical landscape is undergoing a massive transformation, driven by the increasing demand for stable power grids and renewable energy integration. As a core component in medium to high voltage power systems, the ODMOilFuse (Oil-immersed Fuse) plays a critical role in protecting oil-immersed transformers and distribution networks. Currently, the commercial market for oil-immersed fuses is shifting from standardized mass production to highly customized ODM (Original Design Manufacturer) solutions. This trend is fueled by the diverse technical specifications required by different national grids, from the ANSI standards in North America to the DIN and IEC standards dominant in Europe and Asia.
In the industrial sector, reliability is non-negotiable. Modern OilFuses must withstand extreme thermal stresses while providing precise current-limiting capabilities. Factories worldwide are seeking partners who can offer not just products, but engineered solutions that ensure "zero-downtime" for critical substations. This is where the expertise of a specialized China manufacturer becomes invaluable.

Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a powerhouse of electrical technology. Located in Yueqing, Zhejiang Province—the renowned Electrical Capital of China—we represent decades of specialized manufacturing experience. Our journey from a local factory to an international power technology enterprise is built on the foundation of R&D, rigorous production standards, and an unwavering commitment to service.
As a leading China ODMOilFuse manufacturer, we are designated by the Ministry of Electric Power Industry to produce high-voltage current-limiting fuses and power capacitor protection. Our expertise isn't just in manufacturing; it's in engineering the safety of national grids.
Founded in 1992, spanning three decades of power fuse innovation.
Verified by National High-voltage Electrical Quality Supervision Centers.
Our technical performance meets and often exceeds global benchmarks. We ensure that our ODMOilFuse and related products are fully compliant with: ANSI C37.42, DIN 43625, BS 2692, IEC 60282-1, and IEC 60644. This adherence to international protocols allows our products to be seamlessly integrated into diverse electrical environments across Europe, North America, and the Middle East.





All products have passed rigorous testing at the Xi'an High-voltage Electrical Apparatus Research Institute and the High-Power Test Station of the Electric Power Research Institute. Our quality assurance system is ISO9001:2000 certified, ensuring that every fuse link leaving our factory is a testament to precision engineering.
In high-density cities, space is a premium. Our compact ODMOilFuse designs provide full-range protection for underground and kiosk-style transformers without the need for large switchgear.
Protecting the bridge between DC solar generation and AC grid injection. Our fuses handle the harmonic distortion and cycling loads typical of solar and wind plants.
Designed for long-term durability in remote areas. Our drop-out fuses and oil-immersed links require minimal maintenance, ideal for vast rural networks.
Explosion-proof characteristics and high-breaking capacity make our fuses suitable for protecting transformers in hazardous industrial environments.
Global procurement managers for utility companies and electrical wholesalers look for three core factors: Reliability, Cost-Efficiency, and Supply Chain Speed. As a China-based factory, we leverage the Yueqing industrial cluster to source high-grade silver, high-purity silica sand, and precision ceramics at competitive costs. Our ODM capabilities mean we can produce customized fuse lengths, diameters, and tripping characteristics that match specific legacy systems or new grid developments.
Our products are exported to various provincial power companies in China and have established a robust presence in Southeast Asia, the Middle East, Africa, and Europe. We understand the logistical needs of international trade, providing seaworthy packaging and comprehensive technical documentation.
We use sophisticated testing equipment to verify every performance indicator. High-quality raw materials are the backing of our quality assurance system. We can customize and produce new products at any time according to user needs.
Choosing a specialized China ODMOilFuse manufacturer like Wenzhou Shuguang Fuse Co., Ltd. provides you with a competitive edge in the global market. Our integration of "Development by Science and Technology" ensures that we stay ahead of industry curves, providing 12kV, 24kV, and 36kV solutions that are robust and reliable. Whether you are looking for Back-up Protection for oil-immersed transformers or Full-range current-limiting fuses, our factory offers the scale, expertise, and certification to meet your project's strict requirements.
We sincerely welcome customers from home and abroad to discuss cooperation and work together for the prosperity and development of the electric power industry.
