Description

Outdoor prefabricated transformer substation(Combined Transformer)

Intelligent box substation :
The prefabricated-box substation is one of the most economic, convenient, effective and new distribution equipments. It assembles 12kV(24kV,36kV is available)high-voltage switch cabinet; transformer and low-voltage switch cabinet together, and is movable, assembled in plant.
The prefabricated box substation (Named Box Substation below) has many advantages, such as: completely whole set, small cubage, little area, ingoing load center, improving the power supply quality, reducing the circuit loss, shorten power delivery period, flexible location, adapt to setting, convenient assembly, reliable operation, small investment, rapid effect, and so on. Its widely used in urban republic power distribution, high rise building, residential areas, parks, and high-speed roads, as well as oil fields, industrial and mining enterprises, temporary construction areas. The product accords to the GB/T17467-1998<>, DL/T537-1993<<6-35kv box="" substation="" ordering="" technology="" standards="">>, and other standards.

Main Designation Characteristics

The crust of the substation is designed according to the foreign advanced technology and physical reality. We provide many kinds of crust material such as aluminum alloy steel composite stainless steel board and non metal material(glass fiber).

The HV side use charge switch or vacuum circuit breaker. The transformer could be oil type hermetically-sealed type and dry type.

The proof of the box is double layers structure and between the layers is filled with foam. There are independent boards in HV and LV room, and in the transformer room will install auto thermal controller heater and cooling equipment.

Note: we offer special customized products according to client’s requirement.
