Baoding oil-immersed transformer body (windings and iron core) are installed in the oil tank filled with transformer oil, which is welded with steel plate. The iron core and windings of baoding oil-immersed transformer are respectively fastened with self-locking locking nuts. The height of the transformer, the low-voltage leads and other fastening parts are all fastened with self-locking locking locking nuts. The non-lifting core structure is adopted to withstand the shock of transportation. The coil and core are vacuum dried and the transformer oil is vacuum filtered and filled to minimize moisture inside the transformer.

The oil tank of baoding oil immersed transformer USES corrugated sheet, because corrugated sheet replaced the oil storage tank, the transformer oil is isolated from the outside world, thus effectively preventing the oxygen and water from entering and leading to the decline of insulation performance. In the operation of baoding oil-immersed transformer, the heat of winding and iron core is transferred to oil first, and then to the cooling medium through oil.

The cooling methods of baoding oil-immersed transformer can be divided into the following types according to the size of capacity:

1. Natural oil circulation natural cooling (oil-immersed self-cooling type);

2. Natural oil circulation air cooling (oil immersed air cooling);

3. Forced oil circulating water cooling;

4. Forced oil circulation air cooling.
