Other Details

We manufacture lamination cores like CVT cores, long type cores, lamination core, L type core, EI type, UI types for transformers in different grades and in varying thickness. Our CVT Core are made from CRGO (Cold Rolled Grain Oriented Steel) laminations for CVT. CVT addresses the exact requirements of clients and find application in cores of constant voltage transformers. Our CVT cores cuts energy losses also meet the demands of surface insulation.

The use of CRGO laminations also helps in containing:

  •     Core Loss
  •     Eddy Current Loss
  •     Hysteresis Loss
  •     Inter-laminar Loss
  •     Burrs
The use of CRGO laminations also helps in containing:
