Transformer upgrades

Our company has over 30-years' experience in repair and modernization of transformers in power rating up to 270 MVA and voltages up to 400 kV.

We particularly specialize in upgrading of 240 MVA unit transformers. The company is open to the customers' expectations, ranging from complete transformers to components modernization.

We offers several options of transformer modernization with the use of new windings:

• conventional conductor winding,
• conductors with continuously transposed wires,
• forced and directed oil flow.

Due to transformer upgrades our customers receive:

Increase of:

• Rated power up to 270 MVA,
• Resistance of insulation system,
• Transformer reliability,
• Electric and dynamic resistance.

Decrease of:

• Barren gear,
• Load loss in windings,
• Loss in construction parts.

Assurance of:

• Long transformer life, similar to new units,
• Improved electric resistance.

Other advantages:

• Eliminating existing sources of failures,
• Advanced construction.
