Cast Resin :Cast Resin dry type transformer is a transformer that does not use liquid as insulation for its winding or core. Instead the windings and core are kept within a
sealed cast epoxy resin.
VPI :A vacuum pressure impregnated dry type transformer has an iron core, vacuum pressure resin impregnated high voltage windings and low voltage windings. The low voltage
winding is constructed with conductors.

Dry Type of transformer hassome featured advantages :
Health & safety
Flexibility & Cost Saving
Health & safety
- Hardly inflammable, self extinguishing
- Highly moisture-proof
- No pollution to the environment
- Extremely low content of burnable material
- No content of any halogen, silicones, nitrogen in the insulation
- Free from all restrictions that apply oil type transformers
Flexibility & Cost Saving
- Minimum maintenance is required
- No liquids used ; no risk for leakage
- Repair Possibilities (at site)
- Installation close to the center of major consumers
- Reduce cable costs, transmission losses and installation costs
Health & safety
- Cooling is the most efficient ( up to 40% )
- Low partial discharge, therefore, high life expectancy.
- Excellent insulation level, short circuit and lightning Impulse
- Ability to handle greater short time overloads rather than oil type
