Advantages of cast resin dry-type transformers | ESI ...· Transformer explosions during normal operation are highly unlikely due to the selfextinguishable non-toxic substances utilised, even during external fires. They are also suitable for heavy condensation and polluted environments. Cast resin transformers may also withstand abrupt environmental changes from -25ºC to +40ºC in a very short time.[email protected]
