Product Details

Cast Resin Dry Type Internal ARC High Voltage Substation for Real Estate

 

 

Product Description

 

Prefabricated substations are characterized by their strong integration, small size, compact structure, safe and reliable operation, easy maintenance, and mobility. They are a compact set of distribution equipment that combines high-voltage electrical equipment, transformers, low-voltage electrical equipment, and other components. The box body is made of channel steel, aluminum alloy, and flame-retardant composite materials. Compared with conventional civil-built substations, prefabricated substations have a smaller footprint, typically occupying only 1/10 to 1/5 of the area of a conventional substation of the same capacity, greatly reducing the design work and construction costs.

 

In a power distribution system, prefabricated substations can be used in ring network distribution systems, dual power supply or radiating terminal distribution systems, and are a new type of complete equipment for the construction and transformation of urban and rural substations. Prefabricated substations are suitable for outdoor use, with a rated AC voltage of 12kV on the primary side, a maximum transformer capacity of 1600kVA, and a working frequency not exceeding 50Hz. The substation is connected externally via cable and can be operated from both inside and outside.

 

Prefabricated substations are suitable for use in high-rise buildings, urban and rural areas, residential areas, high-tech development zones, small and medium-sized factories, mines, oil fields, and temporary construction sites, among other locations, as part of a power distribution system that accepts and distributes electrical energy.

Material

 

1.The cabinet door adopts a double beveled edge process, which increases the structural strength of the same material by 50%.

 

2.The installation holes are all made using a multi-layer stamping and stretching process, which reduces the sliding wire situation by more than 80%.

 

3.The inlet and outlet holes adopt a composite structure of knockdown holes and square holes, which can be flexibly selected during on-site installation.

 

4.The box adopts a double folding process, which increases the structural strength of the same material by 50%.

 

5.The control circuit adopts a composite design of debugging mode and fire protection mode, greatly reducing the burning of fan and water pump equipment designed for fire protection during debugging.
