Features of Off load Transformer

  • Electric Circuit is made using electrolytic grade with 99.99% pure High-Quality Copper from our regular and reputed vendor.
  • Magnetic Circuit is made using step-lap design for lower losses and low magnetizing current of the core by using high-quality CRGO material with grades such as ZDKH, ZDMH, AMORPHOUS, MOH, etc.
  • High Dielectric Insulation properties to withstand lightning impulses and voltage surges.
  • ONAN through natural convection for effective cooling through axial and radial ducts.
