Difference between dry transformer and oil transformer

1、Dry-type transformers are more expensive than oil-type transformers.

2、Oil-type transformers generally have a larger capacity than dry-type transformers. Dry-type transformers are generally suitable for power distribution. Most of the capacity is below 3000KVA, the voltage is below 35KV; while oil-type transformers can achieve full capacity and voltage levels from small to large. All voltages.

3、Use place comparison: Dry-type transformers are generally used in indoor, such as comprehensive buildings (basements, floors, roofs, etc.) and crowded places. Oil-type transformers are used in independent substations. Transformers in box substations generally use dry-type transformers, and oil-type transformers are generally used for outdoor temporary electricity use.

4、Oil-type transformers are larger than dry-type transformers. Therefore, when using oil-type transformers, more space is required, and dry-type transformers can only be used when the space is crowded.

5、dry-type transformers mostly use silicone rubber bushings, while oil-type transformers mostly use porcelain bushings. Comparison of load bearing capacity-Generally dry-type transformers should be operated at rated capacity, while oil-type transformers have better overload capacity.
