Products designed, manufactured and tested to comply with national and international standards including IEC-60076 / IEC-60076-11 / ANSI C57 / BS-171
AJTS develops the design using fully computerized techniques. All drawings are prepared on computer using CAD Software. Extensive analysis by an interactive computer program is used to obtain optimum designs, which meet the requirements of the customer specifications and the relevant standards.
High Permeability Cold Rolled Grain Oriented steel is used for core manufacturing. Step lap core construction is used which reduces No Load loss, Excitation current & Noise level.
Windings are made of Electrolytic copper strip, Copper foil or Electrolytic copper wire. For Power Transformers High Voltage & Low Voltage windings are Disc winding. For Distribution Transformers High Voltage winding can be Layer or distributed Cross-over and Low voltage winding can be Copper foil winding or Spiral winding.
Coils are assembled over core leg during this process and necessary HV Phase, HV Tap lead, LV phase and LV neutral Connections are done.
The core and winding assembly is dried under vacuum in order to remove moisture from insulation.
After drying process ends the Megger values of each job are checked and tanking done. The transformer is then filled with oil under vacuum.
Finally the job is tested as per relevant standards and customer’s requirement and dispatched after successfully passing the tests.
