Established in 1992 as Yueqing Shuguang Fuse Factory, we have evolved over three decades into a leading power technology enterprise. Located in Yueqing, Zhejiang—the recognized "Electrical Capital of China"—our facility integrates advanced research, development, production, and global sales. We specialize in high-voltage protection, ensuring the stability of power grids across continents.
As a China Wholesale Expulsion Type Fuse Manufacturer, our commitment goes beyond production; we provide integrated engineering services to meet the most demanding industrial requirements. Our brand, "Shu Rong," is synonymous with reliability and technical excellence in the global electrical market.
The global demand for Expulsion Type Fuses is surging due to the modernization of aging power grids in developed nations and rapid electrification in emerging markets like Southeast Asia and Africa. These fuses remain the most cost-effective and reliable method for protecting overhead distribution lines and transformers.
The industry is shifting towards smart-grid integration and environmentally sustainable materials. Modern expulsion fuses are now designed with high-breaking capacities and polymer insulators to withstand extreme environmental conditions, reducing maintenance costs for utility providers.
At Shuguang, we have transitioned from traditional manufacturing to AI-assisted quality control. By implementing sophisticated testing equipment, we ensure that every expulsion fuse link meets precision-engineered time-current characteristics required for modern protection coordination.
Wenzhou Shuguang Fuse is designated by the Ministry of Electric Power Industry. Our products undergo rigorous testing at the Xi'an High-voltage Electrical Apparatus Research Institute and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.

Our high-voltage current-limiting fuses and drop-out fuses provide primary protection for transformers and capacitor banks in national grid substations across Europe and Asia.
The expulsion type fuse is essential for rural electrification projects, offering a reliable, low-maintenance solution for pole-mounted transformers in remote regions of Africa and South America.
Factories and mining operations utilize our HRC fuses for motor protection and voltage transformer safety, ensuring minimal downtime and maximum worker safety.
Procuring from a specialized Wholesale Expulsion Type Fuse Factory in China like Shuguang offers distinct strategic advantages. Our presence in the "Electrical Capital" allows us to leverage a complete supply chain, from high-grade silver fuse elements to advanced ceramic and polymer insulators. This ensures competitive pricing without compromising on the stringent IEC or ANSI standards required by global utilities.
We don't just manufacture; we innovate. Our team can customize fuse links with specific speed ratios (Type K, T, or S) to match your local protection coordination studies perfectly.
With established sales networks in Southeast Asia, the Middle East, Africa, and Europe, we understand international logistics and compliance requirements for various provincial power companies.
High-quality raw materials and sophisticated testing equipment are the backing of our system. All performance indicators are in line with the corresponding technical conditions.
In recent years, the company has developed rapidly, and its economic and social benefits have improved significantly. Global procurement managers face the challenge of balancing cost with reliability. Shuguang addresses this by providing comprehensive test reports and third-party certifications for every batch.
Our production capacity allows us to fulfill large-scale utility tenders while maintaining the flexibility to produce small-batch custom voltage transformer protection fuses. "Shu Rong" brand products have enjoyed a high reputation among domestic and foreign users due to our process flow discipline and focus on "Survival by Quality."
