Cast resin dry-type transformer(three phase)(outdoor)

Insulation for coil or foil winding is epoxy resin which is cast under vacuum conditions. Compared to oil type transformers, it has a better appearance and modern look. It is also a cleaner technology as there is no messy mineral oil involved during operation or maintenance.

Product Feature And Benefit

  • easy and low expense maintenance where inspection by qualified engineer and cleaning required once a year only*
  • longer insulation and product usage lifetime
  • reduces expensive wiring expenses and electrical losses for low voltage electrical system as transformer is installed nearer the center of load usage
  • able to increase capacity (kVA) by installing additional forced air fans when specified by client before the design process
  • helps the aesthetics of the building site as the transformer is installed inside the building out of public view and uses minimal space
  • can be designed and manufactured to any special requirements

Product Application

  • Suitable for installation inside a building, e.g. hospitals, educational facilities, residential or commercial buildings.
