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