Dry Type Transformer

⒈Open type: It is a commonly used form. Its body is in direct contact with the atmosphere. It is suitable for relatively dry and clean indoor environments (when the ambient temperature is 20 degrees, the relative humidity should not exceed 85%). Generally, there are two cooling methods: air self-cooling and wind cooling.
⒉Enclosed type: The Dry Type Transformer is in a closed shell and is not in direct contact with the atmosphere (due to poor sealing and heat dissipation conditions, it is mainly used in mining and is explosion-proof).
⒊Casting type: Epoxy resin or other resin casting is used as the main insulation. It has a simple structure and small size, and is suitable for transformers with smaller capacity.
