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.
