Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, known globally as the "Electrical Capital of China." We are a comprehensive power technology enterprise integrating R&D, production, sales, and service.
Our journey began in 1992 as "Yueqing Shuguang Fuse Factory." Over three decades, we have evolved from a local workshop into a premier China CustomCapacitorFuses Suppliers & Factory. Our commitment to high-voltage innovation has made us a cornerstone of the domestic and international power grid infrastructure.
Leveraging our deep roots in the industry, we provide bespoke engineering solutions for complex electrical protection needs, ensuring that our clients receive products that are not just standard-compliant, but optimized for their specific industrial environments.
In the modern era of energy transition, Custom Capacitor Fuses have become indispensable. As power grids globally shift towards decentralization, the demand for stable energy storage and power factor correction has surged. From the massive data centers in North America to the burgeoning smart cities in the Middle East, high-quality capacitor fuses ensure that surges and overcurrents do not lead to catastrophic system failures.
The industry is currently moving towards Miniaturization and High-Capacity ratings. Modern capacitors are becoming denser, requiring fuses that can handle higher interrupt ratings while maintaining a compact footprint. Integration with IoT for real-time monitoring of fuse status is the next frontier, allowing for predictive maintenance in utility-scale solar farms and wind turbine arrays.
Global procurement teams are no longer just looking for the lowest price; they are seeking E-E-A-T compliant partners. Reliability in extreme temperatures, compliance with international standards like IEC 60282-1, and the ability of a factory to provide customized "Tail wire recovery" or "Oil-immersed" designs are now critical decision factors for EPC contractors and utility providers.
The role of China CustomCapacitorFuses Suppliers is particularly vital. China's mature supply chain in Yueqing allows factories like Shuguang to source high-grade raw materials and specialized components faster than any other region. This agility enables us to provide "Custom" solutions—where we adjust voltage levels, physical dimensions, and melting characteristics to match the exact capacitive reactance of our clients' systems. Whether it is for 11kV expulsion links or sophisticated 36kV current-limiting fuses, the precision of Chinese manufacturing combined with decades of engineering data makes us a global hub for electrical safety.
Our products are designated by the Ministry of Electric Power Industry. We produce high-voltage current-limiting fuses, power capacitor fuses, voltage transformer protection fuses, and zinc oxide arresters that have undergone rigorous testing.
All performance tests are conducted and qualified by the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute.

In recent years, Shuguang has deepened its quality management system. High-quality raw materials and sophisticated testing equipment are the backing of our "Shu Rong" brand. We don't just sell fuses; we provide systemic security. Our customized production allows us to meet specific needs such as high-altitude performance, anti-pollution features, and specific arc-extinguishing speeds.
Our fuses are used in diverse settings:
• Renewable Energy: Protecting capacitor banks in large solar inverters.
• Urban Infrastructure: High-voltage substation protection in dense European cities.
• Industrial Plants: Motor starting and transformer protection in African mining operations.
• EV Charging Stations: Ensuring circuit safety for rapid charging piles.
Our products are exported to various provincial power companies in China, forming a complete national sales network. Internationally, our presence is strong in Southeast Asia, the Middle East, Africa, and Europe. We adhere to the principle of "Development by science and technology, and survival by quality." As a dedicated China CustomCapacitorFuses Factory, we invite global partners to work together for the prosperity of the electric power industry.
