Located in Yueqing, Zhejiang Province—widely recognized as the "Electrical Capital of China"—Wenzhou Shuguang Fuse Co., Ltd. is a premier power technology enterprise. We integrate cutting-edge R&D, precision production, and global sales service.
Established in 1992 as "Yueqing Shuguang Fuse Factory," we have spent over 30 years perfecting the art of circuit protection. Today, we stand as a cornerstone for China Wholesale Oil Fuse supply, serving both national grids and international industrial giants.
In the modern era of energy transition, the demand for reliable Oil-Immersed Fuses (Oil Fuses) has reached an all-time high. These specialized components are critical for protecting oil-filled transformers and distribution switchgear. Unlike air-insulated fuses, oil fuses leverage the dielectric strength and cooling properties of mineral oil or synthetic fluids to extinguish high-energy arcs safely and efficiently.
International buyers from the Middle East, Europe, and Southeast Asia increasingly seek "Wholesale Oil Fuse" partners who can provide:
Our products pass rigorous testing at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute.
We adhere to ANSI C37.42, DIN43625, BS2692, and IEC standards. Our facility is ISO9001:2000 certified, ensuring every batch meets international safety benchmarks.
Being based in Yueqing allows us to source the highest quality raw materials at competitive rates, a key advantage for Wholesale Oil Fuse procurement.
