KRYFS manufacturers Stacked Transformer Core at both its plants at Palghar (Maharashtra) by the manual method of cutting and fabrication and Kherdi (Dadra Nagar Haveli) where it has 4 GEORG Lines, and annealing furnace in addition to the manual method of cutting.

KRYFS can process Transformer Core upto the maximum width possible in CRGO that is ***0 mm.

The manual method of processing is the conventional method of manufacturing Transformer Core in India. It is used mainly for distribution Transformers at KRYFS. However, even in processing by manual method, strict internal tolerances are maintained while fabrication. Also every Lamination is deburred if required (to improve stacking factor) and finally annealed in the KRYFS electrical roller hearth fast cool furnace as recommended by the manufacturing mills.
