Against the backdrop of rapid development in urban and rural power grid renovation, commercial and residential areas, industrial parks, transportation hubs, and temporary construction power supply, there is a growing demand for outdoor power distribution equipment that occupies less space, enables faster commissioning, operates more stably, and offers enhanced protection. Tian'an has launched the YBTD1 (ZBW)-12 (24) High-Voltage/Low-Voltage Prefabricated (Combined) Substation, which integrates a compact design with standardized performance parameters, delivering a safe, stable, and cost-effective power distribution solution to users.
This series of prefabricated substations is manufactured in strict compliance with IEC 62271-202:2014 and GB/T 17467 standards. It features three independent compartments for high-voltage unit, transformer unit, and low-voltage unit. The substation is equipped with comprehensive anti-misoperation interlocking, automatic ventilation, and anti-corrosion and water-resistant functions. It supports various power supply configurations including ring network, dual power supply, and terminal radial systems, making it adaptable to a wide range of distribution scenarios.
Specifically designed for hot and humid environments such as Southeast Asia, the YBTD1 prefabricated substation offers excellent adaptability. The equipment employs both natural and forced ventilation. An automatic exhaust fan installed at the top of the transformer compartment starts operating when the internal temperature reaches the set value, ensuring normal operation. The enclosure is made of high-quality materials with a superior surface treatment, providing excellent anti-corrosion, water-resistant, and dust-proof performance.
Key Technical Parameters of the YBTD1 (ZBW)-12 (24) High-Voltage/Low-Voltage Prefabricated (Combined) Substation
| Parameter | Value | Technical Advantage |
|---|---|---|
| Rated Capacity | 300–2000 kVA | Suitable for different capacity requirements |
| Rated Voltage | 12(24) kV / 0.4 kV | Standard distribution voltage levels |
| Rated Short-Time Withstand Current | 20 kA / 4s | Ensures equipment safety under short-circuit conditions |
| Protection Class | IP33D (HV compartment) / IP23D (transformer compartment) | Outdoor rainproof and dustproof (Note 1) |
| Ambient Temperature | -25°C ~ +40°C | Customizable 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 | Footprint is typically 1/10 to 1/5 that of a conventional civil substation for the same capacity |
Note 1: The IP23D transformer compartment prevents water spray within a 60° angle from vertical. It is recommended to install an additional canopy when the substation is placed outdoors without overhead shelter.
Note 2: When the ambient temperature exceeds 40°C or the altitude is above 1000m, it is recommended to operate at reduced capacity or contact us for a customized solution.
As a mature prefabricated substation product, the YBTD1 (ZBW)-12 (24) offers a compact structure, stable performance, and high adaptability. It is widely used in urban and rural power grid renovation, residential communities, industrial and mining enterprises, stations and ports, as well as temporary construction power supply. Tian'an continues to provide users with efficient and convenient power distribution solutions featuring standardized design and high reliability.
