Our standard core construction is from CRGO silicon steel laminations.
Computerized design of winding of transformer ensures high dielectric strength, short circuit strength and optimum thermal performance. Windings are crossover/helical/continuous disc type with multiple conductors and transposed at regular intervals to achieve desired eddy current losses.
Core and coil assembly is rigidly supported and clamped by clamping structures. Complete core & coil assembly is dried and impregnated in a specified heating and vacuum cycle. Tanks are designed and fabricated according to the requirement of each individual transformer.
All tanks are tested for leakage and are reinforced to withstand pressure and vacuum that would occur during service. Robust under base is provided for easy movement.
Before painting, shot blasting and phosphating is applied on each and every tank & sub assembly to remove all scale & dust so as to achieve rust free surface.
