Magnetic Circuit of the Transformer is made by assembling high grade Cold rolled grain Oriented Silicon laminations having high permeability and low hysteresis loss. HV and LV windings are made in shape of coils, perfectly circular, with electrolytic grade Copper /Alumium conductor ( as per client’s demand. These coils are dried and pressed to pre-determined stack heights, assembled concentrically on the core and magnetically balanced with respect to each other, thus minimizing mechanical stresses.
Core & Coil Assembly is clamped by clamping structure and is dried for a specified heating cycle, under controlled temperature to drive away any moisture. After drying, the assembly is put inside the prefabricated tank, clamped and filled with filtered, dehydrated Transformer oil. All electrical Connections are made and complete set of fillits and reuired accessoties are fitted. The Transformer after painting becomes ready for testing.
