YB-12/0.4 Series Box Type Substation Prefabricated With IP30 Protection Level

The YB-12/0.4 series prefabricated substation (commonly known as the "European-style" box-type substation) is a complete sets of power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage switchgear into a single, compact, and weather-proof enclosure.
Designed for 12/0.4kV power systems, this series is a modern replacement for traditional civil-constructed substation rooms. It is widely utilized in urban power grid transformations, residential quarters, high-rise buildings, industrial parks, and temporary construction power supplies. Its aesthetic versatility allows it to blend seamlessly into green belts and urban landscapes.

• Integrated "All-in-One" Design: Combines high-voltage energy reception, transformer voltage reduction, and low-voltage distribution. The internal layout is partitioned into independent HV, Transformer, and LV compartments to ensure maximum safety.

• Landscape Compatibility (Aesthetic Customization): The enclosure can be customized with various materials—including specialized wood-grain composite, cement-fiber, or landscape-painted steel—to harmonize with the surrounding environment.

• Rugged & Weather-Proof: Engineered for outdoor longevity with a protection level of IP30 (or higher upon request). The shell features excellent thermal insulation and ventilation systems to prevent condensation and overheating.

• Rapid Deployment & Space Efficiency: Compared to traditional brick-and-mortar substations, the YB-12/0.4 requires 70% less land and can be fully installed and commissioned in a fraction of the time.

• Safety Interlocking: Features a sophisticated mechanical interlocking system to prevent misoperation, ensuring the safety of maintenance personnel.

• Ambient Temperature: Upper limit +40°C, Lower limit -25°C.

• Altitude: ≤ 1,000 meters (Special high-altitude designs available).

• Wind Pressure: ≤ 700Pa.

• Humidity: Daily average ≤ 95%; Monthly average ≤ 90%.

• Seismic Resistance: Up to Level 8.

• Installation Site: Free from violent vibrations, harmful corrosive gases, and explosive hazardous materials; vertical tilt ≤ 3°.

• Ultimate Space Efficiency Compared to traditional brick-and-mortar substation rooms, the YB-12/0.4 reduces the required land footprint by up to 70%. Its highly integrated "compact" layout allows for installation in narrow green belts, sidewalk corners, or between industrial buildings without sacrificing power capacity.

• Landscape-Integrated Aesthetics We offer "Aesthetic Customization" that transforms a utility box into a landscape feature. Whether you require a wood-grain finish for a park, a stone-texture facade for a premium residential area, or a modern metallic shell for an industrial zone, our enclosures are designed to harmonize with your specific environment.

• Triple-Chamber Safety Isolation The interior is strictly partitioned into three independent compartments: High Voltage, Transformer, and Low Voltage. This physical isolation prevents fault cascading and allows maintenance personnel to work in one section with zero risk of accidental contact with other live components.

• Superior Thermal & Anti-Condensation Control Equipped with an intelligent temperature control system, the substation features both natural louvered ventilation and automatic forced-air cooling fans. Combined with a high-performance heat-insulating roof, the system effectively prevents internal condensation and ensures stable operation even in direct sunlight or high-humidity tropical climates.

• Unmatched Corrosion Resistance Our enclosures are treated with a multi-layer protective coating that exceeds standard industrial requirements. Whether it's the GRC (Glass-fiber Reinforced Cement) shell or the Aluminum-Zinc coated steel, JNCN substations are built to resist salt spray, acid rain, and UV degradation for a service life of over 25 years.

• "Plug-and-Play" Rapid Commissioning The YB-12/0.4 is 100% factory-prefabricated, wired, and tested. Once it arrives at your site, it only requires basic foundation mounting and cable connection. This eliminates the weeks of on-site construction and complex electrical wiring typical of traditional substations, significantly accelerating your project timeline.
