Dry-Type Transformer Cast Resin Type

A dry type transformer is defined as a transformer that uses air—instead of liquid—as the insulating and cooling medium for its windings and core,.

Dry type transformers are widely used in various industries and applications because of their safety, reliability, and environmental benefits. They can operate in harsh conditions such as high humidity, fire risk, and seismic events without compromising their performance or posing any hazard to people or property.

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.

It's suitable for high humidity areas, indoor installations, and fire-risk areas because it is non-hygroscopic, non-inflammable, and maintenance-free. It can also withstand overloads, partial discharges, and low losses, resulting in high efficiency and long service life.

A CRT is available in ratings from 50 kVA to 12,500 kVA, with insulation class of F/H 

Main Features and Benfits:

  • With a variety of environment
  • High performance on insulation system 
  • Lower installation costs than oil-liquid transformer
  • Maintenance-free,
  • With overload capacity, adding cooling fans

Dry Type Transformer VPI Type
Dry Type Transformer VPI Type

Vacuum pressure impregnated transformer (VPI) is a type of dry type 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.
