General Information

We offer innovatively propelled scope of Dry Type VPI (Vacuum Pressure Impregnated) Transformers with Off Circuit Tap Links (up to 5000 KVA in 11 KV Class.), utilizing CRGO M3 to M5 MOH Lamination and Electrolytic Grade 99.9% unadulterated copper. These transformers are intended for inconvenience free execution, with low power loss and low noise. Utilization of present day fabricating methods and ideal use of dynamic materials guarantees cost viability, dependability and a long inconvenience free execution.

Our Ventilated Dry Type Transformer are fitted in fenced in area for Indoor establishments and are absolutely upkeep free and safe from flame as the material utilized is metal, clay, NOMEX and other non inflammable material. In Dry Type Transformer as there is no oil, hence maintenance is distinctly less demanding and there is no way of spillages and there is negligible nontoxic smoke if there should be an occurrence of flame. Utilization of Class "F"/"H" protection expands the warmth bearing limit and empowers the utilization of the transformer in damp and artificially contaminated environment.
