Against the backdrop of rapid development in urban and rural power grid upgrading, commercial residential communities, industrial parks, transportation hubs, and temporary construction power supply, the demand for outdoor power distribution equipment with smaller footprint, faster commissioning, more stable operation, and enhanced protection continues to rise. TIANAN introduces the YBTD1 (ZBW)-12 (24) High-Voltage/Low-Voltage Prefabricated Substation, which provides users with a safe, stable, and economical power distribution solution through integrated design and standardized performance parameters.
This series of prefabricated substations is manufactured in strict accordance with IEC 62271-202:2014 and GB/T 17467 standards. It integrates the high-voltage unit, transformer unit, and low-voltage unit into three independent compartments. The substation is equipped with comprehensive anti-misoperation interlocks, automatic ventilation, anti-corrosion, waterproofing, and dust protection functions. It supports various power supply modes such as ring network, dual power supply, and terminal radial, offering flexible adaptability to different application scenarios.
Specifically designed for high-temperature and high-humidity environments such as Southeast Asia, the YBTD1 prefabricated substation exhibits excellent environmental adaptability. The equipment adopts both natural ventilation and forced ventilation. An automatic exhaust fan is installed at the top of the transformer compartment, which activates when the temperature reaches a set value to ensure normal operation. The enclosure is made of high-quality materials with a superior surface treatment process, providing excellent corrosion resistance, waterproofing, and dust protection.
| Parameter | Value | Technical Advantage |
|---|---|---|
| Rated Capacity | 300 – 2,000 kVA | Adapts to various capacity requirements |
| Rated Voltage | 12 (24) kV / 0.4 kV | Standard power distribution voltage levels |
| Rated Short-Time Withstand Current | 20 kA / 4s | Ensures equipment safety under short-circuit conditions |
| Degree of Protection | IP33D (HV Compartment) / IP23D (Transformer Compartment) | Outdoor rainproof and dust protection (Note 1) |
| Ambient Operating Temperature | -25°C ~ +40°C | Enhanced configurations available for high-temperature regions (Note 2) |
| Relative Humidity | Daily average ≤95%, monthly average ≤90% | Suitable for high-humidity environments |
| Dimensions (L × W × H) | 3200–5000 × 1800–2500 × 2500–2850 mm | For equivalent capacity, the footprint is typically 1/10 to 1/5 that of a conventional civil substation |
Note 1: The IP23D-rated transformer compartment prevents water spray within 60° from the vertical. For outdoor installations without overhead shelter, an additional canopy is recommended.
Note 2: When the ambient temperature exceeds 40°C or the altitude exceeds 1,000 m, derated operation is recommended, or please contact us for a customized solution.
As a mature prefabricated substation product, the YBTD1 (ZBW)-12 (24) is widely used in urban and rural power grid upgrading, residential communities, industrial and mining enterprises, stations, ports, and temporary construction power supply scenarios. TIANAN continues to provide users with efficient and convenient power distribution solutions through standardized and highly reliable power equipment.
