Product Introduction

It is a new product that combines the advantages of the pad-mounted transformer (American box transformer) and High voltage/Low voltage prefabricated substation (European-type box transformer), and also belongs to the standardized box transformer of the China State Grid.The product structure is arranged in a zigzag pattern, and the power supply mode is terminal type or ring network type. From left to right there are high-voltage room, transformer room and low-voltage room. The metering room, data acquisition room and DTU room can also be added according to the needs of the intelligent substations in the market. The overall box substation has a total of 6 functional rooms, with compact structure and comprehensive functions.Product capacity range: 630kVA and below can meet the size requirements of 2650 * 1350 * 2100mm (length * width * height), and 630kVA and above can be adjusted according to the actual situation.

Product Features

1. Integrates merits of pad-mounted American-type box transformer and HV/LV European-type prefabricated substation.

2. American-type box transformer features compact structure and small footprint.

3. European-type box owns complete high-voltage protection, while its shortcoming is large floor area, not fit for narrow sites.

4. This 10kV compact prefabricated substation inherits small-size merit of American box transformer and complete high-voltage protection performance of European box transformer.

Use Condition

The width of the product is only 1350mm, it can be applied to the green belt in the middle of the urban road, and will not affect the normal passage of vehicles and pedestrians. High-voltage adopts ring-network cabinet with complete protection functions. Widely used in residential communities, wharves, stations, highways, viaducts and temporary construction-site power supply.

Product Advantages

 1. Small cabinet size, saves floor space, about 1/3 footprint of European‑type box transformer, reduces civil construction cost.

2. Comprehensive high-voltage protection, supports terminal-type and ring-network power supply modes, wide application range.

3. Divided into up to 6 functional rooms, satisfies requirements for intelligent prefabricated substation.

4. Transformer installed in integral enclosed box, low noise and good radiation performance.

5. High overall protection level, suitable for salt-fog and heavy-dust environments.
