Tank: The tank is designed and constructed with mild steel along with radiators, Conservators and other features, forms a complete unit of sufficient mechanical strength and provides optimum support for heat dissipation under energized conditions.
Radiator: Radiators are built of cylindrical tubes made by bending mild steel sheets. These tubes are joined by mig-welding to make the tubes leak proof. Numbers of tubes required are calculated to provide 65®C oil temperatures rise above ambient.
Paint: Color of transformers is RAL 7001 as standard. Transformers are painted by powder coating or spraying method. Moreover, if requested, hot-dip galvanizing tanks can be manufactured.
Core: The transformer core is metered cut from cold-rolled grain-oriented silicon steel (CRGO) of the highest quality, with stepped limb and yoke so as to obtain a maximum possible low loss magnetic circuit, clamped with heavy steel channels and tie rod.
Insulation: The dielectric circuit of transformer which isolates the magnetic and electric circuit and their parts maintaining high insulation level is formed by insulating paper, pressboards, Bakelite and transformer oil of highest quality. Insulation is class F according to IEC.
Winding: The HT and LT windings designed with low current densities, are constructed in multilayered cylindrical structures with off ducts ensuring sufficient mechanical and dielectric strength to survive under fault conditions.
