Box type transformer: equivalent to combined (box type) substation.
The box type transformer is of frame structure, welded with section steel, and coated with aluminum alloy plate and special paint layer to make it have strong mechanical properties, weather resistance and corrosion resistance. When the combined (box type) substation is an integral structure, the box is divided into three relatively independent chambers with steel plates, namely, high-voltage chamber, transformer chamber and low-voltage chamber. The lighting of each room will be automatically shut down with the opening of the door.
The top of the combined (box type) substation is provided with a thermal insulation layer. In high temperature and cold regions, the temperature in the box is easy to accumulate and change and condense, so the thermal insulation layer around the box can be added. In order to stabilize the temperature in the box, the transformer room and low-voltage room are equipped with automatic temperature control devices.

Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). In case of natural air cooling, the transformer can operate continuously for a long time under rated capacity. In case of forced air cooling, the output capacity of transformer can be increased by 50%. It is applicable to intermittent overload operation or emergency overload operation; Due to the large increase of load loss and impedance voltage during overload, it is in a non economic operation state, so it should not be in a long-term continuous overload operation

European transformer is a compact complete power distribution device composed of high-voltage electrical equipment, transformer, low-voltage electrical equipment, etc. The box is made of channel steel, aluminum alloy and flame retardant composite materials. European type transformers are characterized by strong completeness, small size, compact structure, safe and reliable operation, convenient maintenance, and mobility. Compared with conventional civil substations, box type substations with the same capacity usually cover an area of only 1/10~1/5 of that of conventional substations, greatly reducing the design workload and construction amount, and reducing the construction cost. In the power distribution system, it can be used in the ring network power distribution system, as well as the dual power supply or radiation terminal power distribution system. It is a new complete set of equipment for the construction and transformation of urban and rural substations.

Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). In case of natural air cooling, the transformer can operate continuously for a long time under rated capacity. In case of forced air cooling, the output capacity of transformer can be increased by 50%. It is applicable to intermittent overload operation or emergency overload operation; Due to the large increase of load loss and impedance voltage during overload, it is in a non economic operation state, so it should not be in a long-term continuous overload operation
