Types of dry type transformer

Cast Resin Dry Type Transformer (CRT)
A cast resin dry type transformer (CRT) is a type of transformer that uses epoxy resin to encapsulate its primary and secondary windings. This protects the windings from moisture, dust, corrosion, and other environmental factors that can affect their insulation and performance.

Vacuum Pressure Impregnated Transformer (VPI)
A vacuum pressure impregnated transformer (VPI) is a type of transformer that uses class H polyester resin to impregnate its windings under vacuum and pressure. This eliminates any air gaps or voids in the insulation, enhancing its mechanical strength, dielectric strength, and thermal stability.
Cast Resin Dry Type Transformer (CRT) vs. Vacuum Pressure Impregnated Transformer (VPI)
Feature | Cast Resin Dry Type Transformer (CRT) | Vacuum Pressure Impregnated Transformer (VPI) |
Best For | Indoor installations, humid areas, fire-sensitive zones | Outdoor installations, seismic zones, high-temperature areas |
Insulation | Encapsulated with epoxy resin | Impregnated with polyester resin |
Mechanical Strength | Moderate | High resistance to shocks & vibrations |
Fire Resistance | High | Medium |
Maintenance | Maintenance-free | Requires minimal maintenance |
Applications | Hospitals, malls, IT data centers, industrial plants | Renewable energy, marine, mining, outdoor power substations |
