Cast Resin Dry-Type Transformer (CRT)
Cast Resin Dry-type Transformers are the most suitable transformers for the distribution of electricity with high safety features. They do not propagate fire. They are self-extinguishing and in the event of a breakdown, there is no risk of leakage of inflammable or contaminating substances like oil. Cast Resin Transformers are maintenance-free, no checking of oil is required. Moreover, due to the partial discharge feature, they have a longer service life. All the above-mentioned features make it the market’s safest and most reliable transformer
