Dry-type Transformers Have Maintenance-free Characteristics

15 kva dry type transformer does not employ oil immersion cooling or liquid insulation media, but instead uses epoxy resin casting or natural air cooling. Therefore, 100 kva dry type transformer eliminates traditional steps such as oil testing, oil tank maintenance, and oil treatment. This 1600 kva dry type transformer design stems from the integrated assembly of the solid insulation of the winding structure and the core system.

Structurally, 30kva dry type transformer uses vacuum impregnation-epoxy resin technology to protect the high-voltage/low-voltage windings, isolating the insulation layer from the environment and reducing the risk of moisture, dust intrusion, and oil mist contamination. The cooling system is typically designed as air-cooled or naturally ventilated, eliminating the need for oil pumps, oil coolers, or complex circulation systems.
