Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, the electrical capital of China. As a premier power technology enterprise, we integrate research, development, production, sales, and service under one roof. Our heritage dates back to the "Yueqing Shuguang Fuse Factory," established in 1992, giving us over three decades of specialized experience in the Wholesale Utility Fuses sector.
Under our flagship brand "Shu Rong," we have built a reputation for reliability. We are officially designated by the Ministry of Electric Power Industry to produce high-voltage fuses across various voltage levels, current-limiting fuses, and specialized protection devices for power capacitors and transformers.
Global power grids are evolving into "Smart Grids." Our fuses are designed to handle the bidirectional power flows and transient stability requirements of digitized networks.
The rise of solar farms and wind turbines requires specialized DC fuses and high-voltage current-limiting fuses to protect sensitive inverter systems.
With the global push for Electric Vehicles, we provide wholesale EV fuses critical for charging stations and onboard battery protection.
Our products undergo rigorous evaluation at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute. We ensure full compliance with:
Understanding local needs is key to being a top-tier Wholesale Utility Fuse Supplier. Our products are engineered for diverse environments:
Protecting high-value transformers and switchgear from short-circuit faults in urban distribution networks.
Our Drop-Out Fuse Cut Outs are widely used in remote areas of Africa and SE Asia for easy maintenance and visible fault indication.
Ensuring continuous uptime for heavy manufacturing plants by providing precise overcurrent protection.
Our sales network spans across China's provincial power companies and extends globally to Southeast Asia, the Middle East, Africa, and Europe. We consistently rank among the top in the industry for domestic and export sales.
We don't just sell off-the-shelf products. Our engineering team can customize fuse parameters (current rating, dimensions, voltage) to meet specific national standards or unique project requirements.
