Industrial-grade fuses designed for maximum reliability and safety.
Established in 1992, Wenzhou Shuguang Fuse Co., Ltd. is strategically located in Yueqing, Zhejiang Province—the world-renowned "Electrical Capital of China." For over three decades, we have evolved from the "Yueqing Shuguang Fuse Factory" into a modern powerhouse of electrical innovation.
As a leading power technology enterprise, we integrate research, development, production, sales, and service. Our deep-rooted expertise in China CustomElectricityFuses allows us to serve the most demanding utility and industrial sectors worldwide with precision-engineered solutions.
Navigating the evolving landscape of power protection technology.
The global demand for high-voltage and medium-voltage fuses is witnessing an unprecedented surge. As nations transition toward Smart Grids and Renewable Energy sources, the need for reliable circuit protection has never been more critical. Traditional power systems are being augmented by solar farms, wind turbines, and massive battery storage facilities—all of which require specialized CustomElectricityFuses to prevent catastrophic failures and ensure continuous power delivery.
Modern global procurement teams are no longer just looking for a vendor; they are looking for a strategic partner who understands IEC, DIN, ANSI, and BS standards. Reliability, traceability, and customization are the three pillars of modern industrial procurement. Whether it's a utility provider in Europe or a manufacturing plant in Southeast Asia, the requirement for fuses that can withstand extreme environmental conditions while providing precise current-limiting performance is universal.
Designed for integration with modern monitoring systems and automated substations.
Tailored voltage ratings and breaking capacities for specific industrial applications.
Decades of proven field experience and adherence to the strictest global safety norms.
Validated by world-class testing institutions.
At Wenzhou Shuguang Fuse Co., Ltd., our products are designated by the Ministry of Electric Power Industry. We manufacture a comprehensive range of high-voltage current-limiting fuses, power capacitor protection fuses, voltage transformer protection fuses, and drop-out fuses. Our quality assurance system has passed ISO9001:2000 certification, ensuring every unit leaving our factory is of impeccable quality.
Our technical performance meets and exceeds:
Why global enterprises choose Shuguang as their primary supplier.
Being in Yueqing gives us access to a complete upstream and downstream industrial chain, reducing production time and costs significantly while maintaining high quality.
Our products are validated by the Xi'an High-voltage Electrical Apparatus Research Institute and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.
Unlike standard retailers, our status as a direct factory allows us to customize performance indicators and dimensions according to specific regional electrical requirements.
Where our fuses make a difference every day.
From the high-demand provincial power companies in China to the emerging markets in Southeast Asia, Africa, and Europe, Shuguang fuses protect infrastructure worth billions. Our fuses are integrated into oil-immersed transformers, outdoor distribution lines, and underground power networks, proving their resilience in every climate.
A complete portfolio of current-limiting and expulsion fuses.
Where science meets survival.
The company adheres to the principle of "Development by science and technology, and survival by quality". While vigorously developing new products, we have always attached importance to the process flow. High-quality raw materials and sophisticated testing equipment are the backing of our quality assurance system.
In recent years, we have integrated AI-driven design simulation to predict the thermal performance of our High-voltage fuses under extreme overload conditions. This allows us to produce "Back-up" fuse-links that operate exactly when needed, protecting expensive transformers and switchgear from thermal and mechanical damage.
