As the economic locomotive of Vietnam, Ho Chi Minh City (HCMC) is undergoing a massive transformation in its energy infrastructure. With the rapid expansion of industrial zones such as Tan Thuan Export Processing Zone and Saigon Hi-Tech Park, the demand for reliable High Voltage (HV) protection has never been higher.
In the context of Vietnam's Power Development Plan VIII (PDP8), Ho Chi Minh City is prioritizing smart grid integration and renewable energy stabilization. High Voltage Fuse manufacturers and factories are playing a critical role in this transition. Our expertise in DIN Standard current-limiting fuses and medium-voltage HRC fuses aligns perfectly with the technical requirements of EVN HCMC (Electricity Vietnam Ho Chi Minh City).
Factories in the region are increasingly moving toward Industry 4.0, requiring fuses that can handle high-density power loads without compromising on safety. From 12kV distribution lines to 36kV heavy-duty industrial substations, the localization of high-quality fuse components ensures that HCMC’s manufacturing backbone—spanning electronics, textiles, and automotive—remains operational 24/7.
Wenzhou Shuguang Fuse Co., Ltd. is located in Yueqing, Zhejiang Province, the electrical capital of China. We are a power technology enterprise integrating research, development, production, sales, and service. The predecessor of our company was "Yueqing Shuguang Fuse Factory," established in 1992.
With over three decades of experience, we have mastered the art of high-voltage circuit protection. Our expansion into the Southeast Asian market, specifically establishing strong ties with partners in Ho Chi Minh City and Binh Duong, has allowed us to customize our products for tropical climates, ensuring high performance in high-humidity and high-temperature environments typical of Vietnam.
It is designated by the Ministry of Electric Power Industry to produce high-voltage fuses of various voltage levels, high-voltage current-limiting fuses, high-voltage fuses for power capacitors, voltage transformer protection fuses, zinc oxide arresters, drop-out fuses, high-voltage insulators, etc.
Our products have passed the high-power test station of the Electric Power Research Institute of the Ministry of Electric Power, the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center, the Xi'an High-voltage Electrical Apparatus Research Institute, and the High-Voltage Electrical Apparatus Laboratory. All performance tests are qualified.
The industry trend in Ho Chi Minh City is shifting towards "Smart Protection." Modern factories are no longer satisfied with basic circuit breaking; they require high-precision HRC fuses that integrate with IoT sensors for real-time monitoring. Our manufacturing process incorporates AI-driven quality control, ensuring each fuse element—whether silver or copper—is calibrated to the exact micro-millimeter for consistent trip speeds.
Furthermore, the Electric Vehicle (EV) revolution in HCMC, led by pioneers like VinFast, has created a niche for EV-specific fuses. High Voltage DC protection is now a requirement for charging piles located in District 1 and District 7 high-rises. As a leading manufacturer, we are at the forefront of this localization, providing high-breaking capacity fuses that protect expensive EV charging modules from transient overcurrents.
Our products are exported to various provincial power companies in China, forming a complete sales network. Our international reach has expanded significantly, with new high-voltage fuses and high-voltage current-limiting fuse products being exported to Southeast Asia (Vietnam, Thailand, Malaysia), the Middle East, Africa, and Europe.
The company adheres to the principle of "Development by science and technology, and survival by quality". We sincerely welcome customers from home and abroad to discuss cooperation and work together for the prosperity of the electric power industry.
In recent years, the company has developed rapidly, and its economic and social benefits have improved significantly. While vigorously developing new products, we have always attached importance to the process flow. High-quality raw materials and sophisticated testing equipment are the backing of our quality assurance system.
All performance indicators are in line with technical conditions, and new products can be customized and produced at any time according to user needs. The "Shu Rong" brand has enjoyed a high reputation among global users.

Choosing the right high voltage fuse factory is critical for long-term project viability in Vietnam's specific tropical climate. We understand the challenges of thermal stress and oxidation in Southern Vietnam. That is why our silver fuse elements are encapsulated in high-strength alumina ceramic tubes, filled with chemically pure quartz sand for maximum arc quenching capability.
Our commitment to Ho Chi Minh City’s industrial growth extends beyond just manufacturing. We provide full technical documentation, coordinate with local logistics at the Cat Lai Port, and offer technical training for substation maintenance teams. When you partner with us, you are not just buying a component; you are investing in a 30-year legacy of electrical safety.
