We manufacture dry type transformers (V.P.I) industrial, substation & distribution up to 2 mva and 11 Kv with an cooling systems. These transformers are used when it has to be located near load center and in a fire hazardous place. As there is no oil used in the transformer and special type of fire resistant insulation are used for the windings the fire risk is considerably reduced in this type of transformers.
As per the name of the Dry Type Transformers, it is clear that these have the high temperature insulation systems unlike other liquid fill transformers which are generally cooled with fire resistant liquid. It is widely used in industrial areas, like pharmaceuticals, chemical , electrical, construction etc, in substations for distribution purposes. The manufacturing range of the offered Dry Transformers are up to 2MVA 22 KV which can naturally air cooled. Such Dry Type Transformers have iron core where vacuum get impregnated with high voltage windings and low voltage windings. The low voltage winding is constructed with conductors which Dupond nomex insulating material includes an apparatus to secure the windings in place during a vacuum and pressure resin impregnation process. The result is a coil that exhibits high short circuit protection due to the tightly bond conductors comparable to completely resin encased molded transformers at a substantially reduced cost.
