The global demand for CECertificationCapacitorFuses has seen an exponential rise as power systems transition toward greater efficiency and stability. As modern electrical grids become more complex with the integration of renewable energy sources, the role of high-voltage capacitor protection becomes paramount. These specialized fuses are designed to protect power capacitors from internal faults and external system surges, ensuring the continuity of reactive power compensation.
Currently, the industrial sector accounts for over 40% of global fuse consumption, driven by massive investments in smart grid technology across Europe, North America, and Southeast Asia.
The shift towards HVDC (High Voltage Direct Current) transmission and EV charging infrastructure requires fuses with higher breaking capacities and faster response times.
CE Certification is no longer just a regulatory requirement but a symbol of trust and safety that global procurement officers prioritize for cross-border projects.
Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, known as the electrical capital of China. We are a power technology enterprise integrating research, development, production, sales, and service. Our journey began in 1992 as the "Yueqing Shuguang Fuse Factory," and over the past three decades, we have evolved into a global leader in circuit protection.
With a foundation built on 30+ years of expertise, we specialize in high-voltage fuses of various voltage levels, including specialized solutions for power capacitors and transformer protection. Our dedication to the "Development by science and technology" philosophy has placed us at the forefront of the Chinese electrical industry.
