The difference between dry-type transformers and oil-immersed transformers

1. In terms of price, dry-type transformers are more expensive than oil-immersed transformers.
2. In terms of capacity, there are more large-capacity oil-immersed transformers than dry-type transformers.
3. Dry-type transformers are required in comprehensive buildings (basements, floors, roofs, etc.) and densely populated fields.
4. Oil-immersed transformers are used in independent substations.

5. Oil-immersed transformers are easy to use in areas where the regional climate is relatively humid and sultry. If a dry-type transformer is used, it must be equipped with forced air cooling.
