Open designing: A 2.5 mva air insulated dry type transformer adopts an opening design. its windings and insulation materials directly exposed to the air rather than enclosed in an enclosure. This design makes the transformer more convenient to maintain and service because internal components are more clear to see and access.
Natural cooling: Unlike 2.5 mva cast resin dry type transformers, 2.5 mva air insulated dry type transformers usually rely on natural cooling, which uses air to dissipate heat from the transformer. This design simplifies the transformer structure and reduces maintenance costs since no additional cooling equipment is required.
High level of safety: Although 2.5 mva air insulated dry type transformers do not have an enclosed casing to protect internal components, their design still focuses on safety. The insulation materials and windings are usually highly durable and fire resistant, ensuring the safety of the transformer during operation.
