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
