Wenzhou Shuguang Fuse Co., Ltd.
Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, the electrical capital of China. As a premier power technology enterprise, we integrate advanced research, development, production, sales, and service. The company's heritage dates back to 1992, established as "Yueqing Shuguang Fuse Factory."
For over three decades, we have remained at the forefront of the ODMFuseVoltage industry, evolving from a local workshop into a globally recognized factory serving major provincial power companies in China and international partners across Europe, the Middle East, and Southeast Asia.
The electrical protection industry is undergoing a digital and structural transformation. As global energy demands shift toward renewables, the requirements for fuse technology have become more stringent.
Global power grids are aging, particularly in North America and Europe. There is a massive surge in procurement for high-voltage current-limiting fuses and polymeric insulators to upgrade existing substations for better reliability and lower maintenance costs.
The rise of Electric Vehicles (EVs) has created a new niche for high-speed, high-voltage fuses. Our factory has pioneered Wholesale EV Fuse solutions that protect battery packs and charging infrastructure from catastrophic short-circuit events.
Solar and wind farms operate in harsh environments. The demand for "Shu Rong" brand polymeric insulators and lightning arresters is peaking due to their superior anti-pollution performance and resistance to UV degradation compared to traditional porcelain.
Our commitment to E-E-A-T is backed by rigorous testing. We are designated by the Ministry of Electric Power Industry to produce high-voltage fuses across various voltage levels.
All products have passed inspections at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute. We strictly adhere to:
Our HRC fuses provide critical back-up protection for oil-immersed transformers in urban substations, preventing internal fault damage.
Specially designed voltage transformer protection fuses and capacitor protection fuses ensure stability in reactive power compensation systems.
For compact switchgear, our 10KV 0.63A miniature fuse links offer precision protection in space-constrained environments.
Located in Yueqing—the Electrical Capital—we have immediate access to high-purity copper, specialized ceramics, and advanced polymers, ensuring competitive pricing without compromising quality.
Every national grid has unique voltage specifications. We specialize in customizing ODMFuseVoltage products to meet specific regional current-time characteristics and physical mounting requirements.
We continuously invest in process flow optimization. High-quality raw materials and sophisticated testing equipment are the backing of our quality assurance system, ensuring "Shu Rong" brand excellence.
