Divisions >>Transformer Business

The Transformer Business Unit is a fully integrated manufacturing unit for complete design, manufacture, testing and delivery of transformers and transformer accessories.

We know core/coil assemblies are the heart of the transformer, and we have focused our engineering and manufacturing expertise on improving core and coil design.

As a result, we have invested heavily in product design, manufacturing processes, personnel training, and materials to make WESCOSA product performance the best in the industry.

Two types of core/coil design are adopted to suit the requirements of different ratings of transformers using state of the art core processing and winding equipment.

• Wound core

• Stacked core

Wound core type construction (5 legged) is used predominantly for lower kVA ratings of transformers. Continuous flux with step lap joints in wound core loops minimizes losses.

Stacked-core type construction adopted for higher kVA ratings of transformers. Step lap joints are also used to reduce the no load losses.

Raw materials are procured from reputed Suppliers around the world.

The best grades of silicon steel including laser annealed grades are used for core construction to minimize the excitation losses.

Electrical grade, soft, copper foils suitable for transformer windings is used for low voltage winding.

Enamel covered round or rectangular conductors conforming to class H insulation system ratings (minimum) are used for high voltage windings.

Epoxy dotted insulation paper is used throughout the coil for increased short circuit strength. Cooling ducts placed inside the coil, where requires, will minimize the temperature rise and the hotspot temperature.

The following types of transformers are manufactured in accordance with applicable standards and customer specification requirements:
