Grant Transformers supplies high quality innovative products with performance guarantees and flexible designs, according to AS/IEC, TSE, BS standards. Grant Transformers has cast resin transformers have a 5 seconds Short Circuit Withstand and E2, C2, F1 Certificate from DNV/KEMA- The Laboratory in Netherlands for CAST RESIN Transformers. Cast resin transformers pose ZERO risk of oil leaks and pollution of the environment. Transformer explosions during normal operation are highly unlikely due to the self extinguishable 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.

Grant Transformers  has also deals with Cast Resin Transformers for outdoor application as high as IP44 ratings. Its can be used natural air convection to cool itself. Thus, it eliminates extra costs & labour for liquid-level checking, oil testing, oil recycling costs, & dielectric testing for moisture absorption, gasket replacements. Being almost maintenance free, this transformer technology is ideal for most applications and one can monitor temperature rise with PT100 probes for added piece of mind.
