We also offer wide range of Dry-Type three phase transformers. Dry type transformers have high mechanical & dielectric strength. Dry type transformers (Vacuum Pressure Impregnated) of 11 KV voltage class have high grade insulation (i.e. class ‘F’ / class ‘H’ / class ‘C’) with bus-bars (Standard) as termination & cable boxes (on request). These generally have AN (Neutral or Natural) / AF (Forced) type of cooling with enclosure protection such as IP21 / IP33 / IP43 / IP00 & Non-ventilated. These are followed as per standards like BIS / IEC / ANSI C57.12.01 / IEEE & IS 1117. Dry type transformers have high dynamic short-circuit strength with good impulse withstand capability which (VPI) ensures void free insulation system. These have better resistance to temperature fluctuations, are immune to polluted atmosphere & are moisture ingress resistant. These are environment friendly & have easy maintenance. These are highly suitable for indoor use & have low fire hazard possibilities.
