Vietnam is currently experiencing an unprecedented industrial boom. With the government’s Power Development Plan VIII (PDP8), the nation is aggressively expanding its electrical infrastructure to support rapid urbanization and the influx of global manufacturing giants in provinces like Bac Ninh, Binh Duong, and Dong Nai. As a leading Surge Arrester Supplier in Vietnam, we recognize that this expansion requires world-class lightning protection to prevent catastrophic equipment failure.
Vietnam's tropical monsoon climate makes it one of the regions with the highest lightning strike frequencies in Southeast Asia. This environmental factor, combined with the high humidity and coastal salinity found in areas like Da Nang and Hai Phong, demands surge arresters that are not only high-performing but also highly durable. Our polymer-housed zinc oxide arresters are specifically engineered to withstand these harsh conditions, ensuring the stability of Vietnam's national grid (EVN).
Ensuring uninterrupted power for Vietnam's growing industrial zones.
Supporting PDP8 projects and high-voltage transmission lines.
Established in 1992 as "Yueqing Shuguang Fuse Factory," Wenzhou Shuguang Fuse Co., Ltd. has evolved into a powerhouse of electrical technology. Located in Yueqing, the "Electrical Capital of China," we have dedicated over three decades to the research, development, and production of high-voltage protection devices.
As a trusted Surge Arrester Supplier, we don't just sell products; we provide peace of mind. Our integration of R&D and manufacturing allows us to customize solutions for the unique technical requirements of the Vietnam market, including specific voltage levels and mounting configurations used by local power utilities.
Our surge arresters and fuses are designed to meet and exceed international benchmarks, ensuring they are ready for the most demanding applications in Vietnam's industrial and renewable energy sectors.
We are 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.
Compliance Standards: Our products meet ANSIC37, 42, DIN43625, BS2692, IEC282-2-1995, IEC60644, IEC60470, IEC60282-1, IEC269-2, and GB15166.1/.2/.5, GB13593, DL/T640-1997, VDE0636 standards. This rigorous compliance makes us a preferred Surge Arrester Supplier in Vietnam for projects funded by international investment.
Vietnam is a regional leader in solar and wind power. Our surge arresters protect massive solar farms in Ninh Thuan and offshore wind projects in Binh Thuan from atmospheric surges.
From Samsung’s facilities in Bac Ninh to Intel’s in Ho Chi Minh City, we provide the localized surge protection necessary to keep high-tech manufacturing lines running smoothly.
As Hanoi and Da Nang transition to smart city technologies, our protection devices ensure the longevity of sensitive IoT sensors and communication equipment.
Our economic and social benefits have improved significantly through continuous deepening of our quality management system. High-quality raw materials and sophisticated testing equipment are the backbone of our quality assurance system. We specialize in producing custom solutions for the Vietnam surge arrester market, ensuring every unit is tested for the specific peak voltages it will encounter in the field.
The "Shu Rong" brand has enjoyed a high reputation among domestic and foreign users, particularly in Vietnam where our export volume continues to grow annually.
In the rapidly evolving landscape of Southeast Asia, Vietnam stands out as a beacon of industrial growth. However, this growth brings with it complex challenges in power management and protection. As an expert Surge Arrester Supplier in Vietnam, we have observed that the transition from traditional manufacturing to high-tech industry requires a corresponding shift in electrical safety standards. The vulnerability of modern electronics to transient overvoltages means that the surge arrester is no longer just a peripheral component; it is a critical safeguard for the nation's digital and industrial economy.
Vietnam's Power Market Trends: The recent approval of PDP8 underscores a massive move toward decentralization of power sources. With a focus on reducing carbon emissions, Vietnam is integrating vast amounts of solar and wind energy. These renewable sources are often located in remote areas with high lightning exposure. Our range of zinc oxide (ZnO) surge arresters, which feature gapless designs and superior non-linear characteristics, are ideally suited for these applications. Unlike traditional silicon carbide arresters, our ZnO technology offers faster response times and better protection levels for sensitive inverter systems used in solar farms across the Central Highlands.
Technical Expertise & Local Adaptation: One of the key reasons we have become a leading supplier of surge arresters to Vietnam is our commitment to local adaptation. We understand that a surge arrester installed in the humid, salt-laden air of the South China Sea coast requires different leakage current characteristics than one installed in a dry, inland environment. Our polymer-housed units offer superior hydrophobic properties, preventing tracking and flashovers caused by pollution and moisture—a common issue in Vietnam's industrial coastal hubs.
The Role of High-Voltage Fuses: While surge arresters manage voltage transients, our high-voltage fuses, such as the HRC Current Limiting Fuse and Drop Out Fuse Cutouts, handle overcurrent protection. In Vietnam's bustling urban centers like Hanoi and Ho Chi Minh City, distribution transformers are often under heavy load. Our porcelain and polymer fuse cutouts provide reliable isolation and protection, ensuring that a localized fault doesn't lead to a widespread blackout. This dual approach to protection—voltage and current—makes us a comprehensive partner for Vietnamese electrical engineers and procurement officers.
Authoritative Quality Control: Our reliability is backed by rigorous testing. Every surge arrester and fuse that leaves our factory has been subjected to tests at the high-power test station of the Electric Power Research Institute. For our Vietnamese clients, this means that the products they receive are fully compliant with IEC 60099-4 and IEC 60282 standards, which are the recognized benchmarks for the Electricity Vietnam (EVN) grid. Our ISO 9001:2000 certification further solidifies our position as a trustworthy Surge Arrester Supplier that prioritizes quality over cost-cutting.
In conclusion, as Vietnam continues its journey toward becoming a developed industrial nation, the need for robust, reliable, and technologically advanced electrical protection will only grow. Wenzhou Shuguang Fuse Co., Ltd. remains committed to supporting this journey by providing the highest quality surge arresters and fuses. Whether you are an EPC contractor working on a new substation in the Mekong Delta or a maintenance manager for a factory in Bac Ninh, we are your partner in power security.
