(Summary description)The biggest difference between quality oil immersed transformers and dry-type transformers is whether there is "oil". Since oil is liquid and has fluidity, quality oil immersed transformers must have a casing. The inside of the casing is transformer oil, and the transformer is immersed in the oil.

The biggest difference between quality oil immersed transformers and dry-type transformers is whether there is "oil". Since oil is liquid and has fluidity, quality oil immersed transformers must have a casing. The inside of the casing is transformer oil, and the transformer is immersed in the oil. The coil of the transformer cannot be seen from the outside; while the dry-type transformer has no oil, it does not need a casing, and the coil of the transformer can be seen directly;
Another feature is that there is an oil pillow on the quality oil immersed transformer, and the transformer oil is stored inside, but now there are also new transformers without oil pillow;
For the convenience of heat dissipation, that is, for the flow of internal insulating oil, the quality oil immersed transformer has a radiator designed on the outside, just like a heat sink, but the dry-type transformer does not have this radiator, and the heat dissipation depends on the fan under the transformer coil. The fan is a bit like the indoor unit of a household air conditioner;
The quality oil immersed transformers are generally installed indoors or outdoors in separate transformers due to the need for fire protection, while dry-type transformers must be installed indoors. Generally, they are installed in low-voltage power distribution rooms and installed side by side with low-voltage power distribution cabinets.
