Product Description


Box-type substations have a small footprint. Generally, the floor area of a box-type substation is only 5-6 square meters, or even less at 3-3.5 square meters. They are suitable for use in densely populated industrial and mining enterprises, ports, and residential areas, among other locations, and can extend high-voltage power supply to the load center, reduce the low-voltage supply radius, and reduce losses. The number of low-voltage supply lines is generally 4-6. Box-type substations can shorten the on-site construction period and require less investment.

When using new equipment such as fully sealed transformers and SF6 switchgear, the maintenance cycle of the equipment can be extended, and even maintenance-free requirements can be met. The appearance is novel and beautiful and can be coordinated with the surrounding environment of the substation. For self-maintained box-type substations (250kVA or above), the urban power department requires the use of high-voltage metering. In some cases, more outgoing circuits are required, including setting up standby circuits. In these cases, the designer combines the actual electricity usage and reference to the manufacturer's sample to optimize the design.


Environmental Conditions

Box-type substations are used for high-rise residential buildings, luxury villas, squares, parks, residential areas, small and medium-sized factories, mines, oil fields, and temporary construction power use, among other locations, as part of a power distribution system that accepts and distributes electrical energy. They comply with the standards of GB/T17467 "Pre-installed High-voltage/Low-voltage Substations" and SD320 "Technical Conditions for Box-type Substations."

Environmental conditions for use:

  • Altitude: 1000m or below.
  • Ambient temperature: -25℃ to +40℃.
  • Wind speed: not exceeding 35m/s.
  • Air relative humidity: not exceeding 90% (+25℃).
  • Horizontal acceleration of seismic level: not greater than 0.4m/s, vertical acceleration: not greater than 0.2m/s.
  • The installation site should not have conductive dust or dangerous substances that are corrosive, flammable, or explosive to metals or insulating materials.
  • The installation site should not experience severe vibrations, and the vertical slope should not exceed 3 degrees.

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.
