LV & HV Windings

In distribution and power transformers, windings are made of two components conductor and the insulation materials both provide maximum strength to axial and radial forces and increases the resistance of the winding against overvoltage impulses.

Magnetic Core

The Magnetic core is made up from cold-rolled, grains-oriented (CRGO) and low-loss electrical silicon steel. Core steel can be in different thicknesses and qualities and are made up from high-quality silicon steel such as M3, M4, M5, MOH, ZDKH85, ZDKH95 and Amorphous steel...

Active Part & Assembly

The active part of a transformer consists of the core, coils, upper cover, tap changer, bushings, and protection and connection members on the upper cover. The coils are mounted by squeezing against the core and each

Tanks & Top Cover

The transformer tanks (lower pan and side walls) and top cover are made by using black sheet metal with high quality which is electrically welded.

Painting

Tanks are painted with one coat of primer and one final coat of paint with a total thickness not less than 105 µ (microns) and more coats can be done as per the customer request.

Drying and Oil Filling

The active part through with the assembly operation is dried in a special high-vacuum drying ovens at 110-120 degrees for a period of time, and they are placed in the tank...

Accessories

Transformer accessories are protective and indicative equipment that are used depending on the transformer power& type and customer request.
