Wenzhou Shuguang Fuse Co., Ltd. is strategically located in Yueqing, Zhejiang Province—widely recognized as the "Electrical Capital of China." As a premier power technology enterprise, we integrate research, development, production, sales, and comprehensive services into a single professional entity.
Our journey began in 1992 as the "Yueqing Shuguang Fuse Factory." Over the past three decades, we have evolved into a leading authority in the high-voltage protection industry. Our commitment to excellence has made us a designated producer for the Ministry of Electric Power Industry, specializing in expulsion fuses, current-limiting fuses, and zinc oxide arresters.
The global expulsion fuse market is witnessing a significant surge driven by the rapid modernization of aging electrical grids in North America and Europe, coupled with massive electrification projects across Africa and Southeast Asia. As utilities strive to reduce downtime, the demand for reliable BestExpulsionFuses has become a critical priority for distribution network stability.
Modern trends are shifting toward "Smart Grids." While the core expulsion mechanism remains a physical safety standard, there is an increasing integration of materials that can withstand extreme weather conditions caused by climate change. We are developing fuses with enhanced polymer housing and corrosion-resistant alloys to meet these evolving environmental challenges.
Today's global buyers—from state-owned utilities to private industrial contractors—are no longer just looking for the lowest price. They demand transparency in testing, compliance with international standards (IEC/ANSI), and shortened lead times. Our factory addresses these by maintaining large raw material inventories and automated testing lines.
Located in the heart of China’s electrical hub, we leverage a world-class supply chain. This allows us to offer competitive wholesale pricing without compromising on material quality, from high-grade silver fuse elements to reinforced epoxy tubes.
We don't just manufacture; we innovate. Our technical team can customize fuse links to specific time-current characteristics (TCC) requested by international clients, ensuring perfect coordination with existing grid equipment.
Our products have passed rigorous evaluations at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute. Reliability is engineered into every unit.
With established sales networks in Southeast Asia, the Middle East, Africa, and Europe, we understand the logistical requirements of international trade, including seaworthy packaging and comprehensive customs documentation.
Whether you need your own brand on the product or a specific modification for a local application scenario, our factory provides full-cycle OEM services to support your local market dominance.
We adhere to the principle: "Development by science and technology, and survival by quality." We view our clients as long-term partners in the global electrification journey.
Our expulsion fuses are engineered for diverse environments, ensuring that whether in a humid tropical jungle or a high-altitude mountain range, your equipment remains protected.
In rural electrification, cost-effective and easy-to-replace protection is vital. Our dropout expulsion fuses allow maintenance crews to quickly identify and replace blown links, minimizing outage times in remote areas.
As solar and wind farms expand, our HRC and Expulsion fuses provide the critical secondary protection layer for step-up transformers, handling the unique load profiles of renewable generation.
For factories and heavy industry, our current-limiting fuses ensure that high-fault currents are suppressed before they can damage expensive machinery, following strict IEC 60282 standards.
Our quality assurance system is complete and certified under ISO 9001:2000. Our technical performance meets and exceeds the following international benchmarks:
