Smrtr Technology
1 / 5
A dry type transformer, also known as an air-cooled transformer, utilizes air or gas instead of liquid for insulation and cooling. This design does not immerse its core and windings in insulating oil, making it ideal for various specialized environments.
1. Cast Resin Dry Type Transformer (CRT): Uses epoxy resin to encapsulate windings, protecting them from moisture, dust, and corrosion. Ideal for high humidity and fire-risk areas. Ratings: 25 kVA to 12,500 kVA.
2. Vacuum Pressure Impregnated Transformer (VPI): Impregnates windings with class H polyester resin under vacuum. Enhances mechanical strength and thermal stability. Suitable for seismic events and outdoor installations.
