Personally, I think using oil is better. There are two reasons: 1. The oil-using unit can be installed outdoors, reducing the floor space required for the factory building ； 2. The oil-based cooling system provides good cooling effects, the fan is small, and the transformer generates less noise. Small in size.
What was said upstairs is correct; let me add something more. Oil-immersed transformers are relatively inexpensive, require fewer stringent operating conditions, but involve more maintenance work. Dry-type transformers are the exact opposite. For transformers in high-capacity power supply systems, oil-immersed transformers are recommended as they are more economical and practical.
