Three Phase Distribution Transformers


  • Compact in size: Transformers with Corrugated walls are smaller than Transformers with radiators
  • Improved Heat Dissipation
  • Elegant Appearance
  • The fins have sufficient degree of elasticity to absorb the expansion in volume of the liquid, due to the heating of cooling medium, at the same time providing a large dissipating surface to cool the same cooling medium
