Technical information

  • Transformer production uses only high-quality materials and components that have undergone strict incoming inspection.
  • Magnetic cores are produced on the modern cross-cutting line equipped with automatic core lamination stacking.
  • In blanking and welding operations, automatic cutting and welding equipment is used.
  • For winding, high-performance equipment is used, which allows to make high quality windings, with special attention paid to the winding closeness.
  • Painting of cases and covers is carried out on modern powder painting lines with preliminary surface treatment.
  • Transformer oil passes through several treatment steps, including dehydration, degasification, filtration on automated oil storage and filling line.
