Core Assembly _
Core is built with Cold Rolled Grain Oriented Silicon Steel, low loss silicon steel lamination . Bonded core design/ technique is used to eliminate hole punching and to minimize fixed losses and Magnetizing Current. Use of HiB grade & Laser scribed Laminations and Rigid clamps significantly reduce vibrations and noise level. Cooling ducts are provided in large transformers for efficient circulation of oil to keep temperature of core well within limit without affecting the flux distortion and also in the core suitable insulation paper are inserted between some laminations for the purpose of reducing eddy currents and also minimizing magnetic short circuit.
The steplap or Mitred joints at the core corners ensure a stream line magnetic flux path. The core limb are held with resin bonded glass bands to eliminate limb bolts. Yokes are clamped by solid mild steel plates with yoke stud ensuring high rigidity for withstanding mechanical socks during transportation & Short Circuits. The leg core in a which hard wooden bars are inserted, are tighten with synthetic resin impregnated glass bend.
