Shu Guang
Wenzhou Shuguang Fuse Co., Ltd. is a cornerstone of China's electrical industry. Located in Yueqing, Zhejiang Province—widely recognized as the "Electrical Capital of China"—our company stands as a high-tech powerhouse. We specialize in the integrated research, development, production, and sale of advanced power technology.
Founded in 1992 as "Yueqing Shuguang Fuse Factory," we have spent over three decades perfecting the art of electrical protection. Today, we are designated by the Ministry of Electric Power Industry to produce mission-critical components, including high-voltage current-limiting fuses, zinc oxide arresters, and porcelain insulators.

In the era of Industrial 4.0, the global demand for reliable power protection has skyrocketed. As countries modernize their power grids and transition to renewable energy, Power Fuses have become the unsung heroes of infrastructure. From the bustling industrial zones in Southeast Asia to the renewable energy farms in Europe, the need for OEM power fuses that meet international standards (IEC, DIN, ANSI) is paramount.
The industry is currently shifting toward Miniaturization, High Breaking Capacity, and Smart Integration. We are seeing a massive surge in demand for EV (Electric Vehicle) Fuses and capacitor protection. As urban centers become denser, the reliability of drop-out fuses and transformer protection devices dictates the stability of the entire metropolitan power supply.
International buyers are no longer just looking for "cheap" products. They demand Verified Expertise (E-E-A-T). Global enterprises require suppliers who can provide comprehensive test reports from recognized stations, ensuring that every HRC fuse or insulator can withstand extreme voltage fluctuations and environmental conditions.
Our products have undergone rigorous validation at the Xi'an High-voltage Electrical Apparatus Research Institute and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.
