IEC 60076

IEC 60076-24:2020 applies to medium power transformers from 25 kVA up to 3 150 kVA with highest voltage for equipment up to 36 kV, or in low voltage (LV) networks with the highest voltage for equipment of up to 1.1 kV equipped with voltage regulating devices.

Features Of Transformer

  • We manufacture offload/onload distribution transformers starting from 200 KVA to 5000 kVA under IEC 60076.
  • Designed for a minimum 25 years of life-span with a 24*7 hours of performance, minimum maintenance and silent operation.
  • Indoor/Outdoor Pad Mounted
  • Copper/Aluminium Foil Winding a Thermally Upgraded Paper(TUP) insulation.
  • 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 the transformer.
  • 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 property to withstand lightning impulse and voltage surges.
  • ONAN through natural convection for effective cooling through axial and radial ducts.
  • Copper/Aluminium Foil Winding or multiple paper covering.
