IEC 60076
Features Of IEC 60076
  • Electric Circuit is made using electrolytic grade with 99.99% pure High-Quality Copper from our regular and reputed vendor HINDALCO & STERLITE with Foil winding in L.V coil of transformer.
  • Magnetic Circuit is made using step-lap design for lower losses and low magnetizing current of core by using high quality CRGO material with grades such as ZDKH, ZDMH, AMORPHOUS, MOH, etc.
  • High Dielectric Insulation property to withstand lightening impulse and voltage surges.
  • ONAN through natural convection for effective cooling through axial and radial ducts.
  • Copper/Aluminium Foil Winding or multiple paper covering.
