Engineered for high-performing distribution networks, these core Air-insulated Switchgear units meet EVN requirements and IEC guidelines.
Deep-dive analysis into the localization requirements, EVN compliance parameters, and environmental challenges.
Under Vietnam's National Power Development Plan VIII (PDP8), the country is fast-tracking medium voltage integration of renewable energy. This requires robust, highly reliable switchboards that can cope with frequent grid fluctuations and distributed generation models.
Vietnam's extreme coastal humidity (up to 95%), salt spray corrosion, and ambient temperatures rising past 40°C require custom insulation layouts. Our AIS configurations implement epoxy-resin encapsulation and thermal monitoring to eliminate flashover risks.
Unlike standard 10kV networks globally, the primary distribution standard set by Electricity Vietnam (EVN) revolves around 22kV and 35kV grid voltages. Standardizing switchboards parameters ensures instant integration and faster inspection approval times.
To support Vietnam's goal of becoming a high-income digital economy by 2045, the modernization of power infrastructure is crucial. Rapid urbanization in metropolitan zones like Hanoi, Ho Chi Minh City, and Da Nang, combined with the exponential growth of high-tech manufacturing parks (such as VSIP, Amata, and DEEP C), has driven an unprecedented demand for reliable medium-voltage (MV) distribution equipment.
Air-insulated switchgear (AIS) remains the foundational backbone of industrial distribution due to its straightforward maintenance loop, environmental transparency (mitigating SF6 dependence), and high lifecycle economy. However, deploying standard AIS systems in Vietnam without adapting to the country's local regulatory framework (EVN technical specifications) and geographical demands can result in operational failure and regulatory bottlenecks. Standardized type testing under IEC 62271-200 is an absolute requirement for successful energization on the Vietnam grid.

The strategic supply chain link between Ningbo Port and Vietnam’s growing industrial clusters.
Zeno Electric is strategically situated in Ningbo, one of the world's premier shipping centers. Sourcing MV switchgear from Ningbo allows direct ocean freight access to Vietnam's main ports: Haiphong Port for northern industrial grids (Hanoi, Bac Ninh, Hai Duong) and Cat Lai Port / HCMC Port for southern grids (Binh Duong, Dong Nai). Transit times are often as short as 5 to 7 days, significantly beating European lead times.
Our raw material integration—ranging from high-quality cold-rolled copper sheets to advanced insulation components—ensures that our switchgear stands up to international tier-one specifications at a highly competitive operational cost. Industrial developers in Vietnam can leverage Chinese volume manufacturing to lower their CAPEX by up to 35% compared to Western counterparts.
Vietnam’s local utilities (EVN Northern Power, EVN Southern Power, EVN Hanoi, EVN HCMC) require rigorous paperwork checks before grid energization. All Zeno AIS assemblies undergo systematic verification checks, including:

Deploying resilient switchgear across diverse heavy-duty commercial and natural environments.
Vietnam’s manufacturing hubs (VSIP I/II, Amata, Nhon Trach) process high-tech microelectronics and textiles demanding continuous uptime. Our KYN28 series provides automatic transfer schemes and rapid arc quenching to protect sensitive fabrication lines.
Renewable solar and wind generation in Ninh Thuan and Binh Thuan provinces rely on outdoor switchyards. With heavy maritime salt air, our switchboards use specialized anti-corrosion finishes (C4/C5 grade) and IP54 sealed LV compartments.
For space-confined infrastructure in central Hanoi and HCMC, compact air-insulated RMUs (SM6 equivalents) provide flexible cable entry-exit pathways, reliable mechanical interlocks, and low-maintenance vacuum circuit breakers.
