Our company's quality assurance system is complete and has passed ISO 9001:2000 quality system certification. Products have been rigorously tested at the Electric Power Research Institute of the Ministry of Electric Power and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.





With the rise of Electric Vehicles (EVs), the demand for specialized high-voltage fuses for charging stations and battery protection has skyrocketed. Our factory is at the forefront of this trend, producing CE-certified EV fuses that ensure safety in high-speed charging environments.
Modern cities require compact, highly reliable fuse-links for underground distribution networks. Our DIN standard HRC fuses are designed for space-constrained environments while providing maximum fault protection.
Global procurement teams are now focusing on fuses capable of protecting large-scale battery energy storage systems, which require fast-acting characteristics to protect sensitive power electronics.
Based in Yueqing, we leverage the world's most concentrated electrical supply chain, allowing us to source premium raw materials and provide competitive pricing.
We don't just manufacture; we innovate. Our lab is equipped with high-power test stations to simulate real-world grid faults, ensuring every fuse is "battle-ready".
Our products are exported to various provincial power companies in China and internationally to Southeast Asia, the Middle East, Africa, and Europe.
