  Dry type transformers are those transformers that use air as cooling and dielectric medium instead of conventional technology of transformers which uses mineral oil as a cooling and dielectric medium.

  Vacuum Pressure Impregnated (V.P.I.) Dry Type Distribution Transformers

  V.P.I. is a process which is a step above the conventional vacuum system. V.P.I. includes pressure in addition to vacuum, thus assuring good penetration of the varnish in the coil. The result is improved mechanical strength and electrical properties. These transformers are used in installations within the building premises,crowded and urban areas,overloaded feeders, near to the load centre or even outdoors where there is oil theft.

  We at Shri Ram Group Of Industries utilise a state of art vacuum impregnating system to manufacture Dry type transformers upto 3 mVA 33kV Class.
