Power Transformers

Locomotive and Trackside Power Transformers

The Locotransformer is used for stepping down the voltage level required for motors used in the railway engines. This transformer has low dimension and weight limits.  Height of the unit is reduced by mounting the active part horizontally. We have different range of uniquely designed products like 3900 kVA Foil Wound, 5400 kVA Foil Wound, 6500 kVA for 3-phase Loco, 7500 kVA for 3-phase Loco with advanced design technology to perform seismic and short-circuit conditions, which is developed over the past experiences accompanied with high-end technology for the manufacturing and quality tools for cost-effectiveness for long life with low maintenance.

They are designed with H class conductor insulation and filled with silicone oil. To get a compact but reliable design OFAF or ODAF cooling is applied. Height of the unit is reduced by mounting the active part horizonally.

The Trackside Power Transformers are used for stepping down the voltage levels for the railway network. They are used to provide single phase supplies for train overhead systems. The duty of traction supplies transformers is a particularly difficult one, as overloading up to twice full-load current can appear. Furthermore, trackside transformers need to withstand system short-circuits which may be as high as 250 per year of varying magnitude up to full fault current. Height of the unit is reduced by mounting the active part horizontally. We have a wide range of uniquely designed products with advanced design technology to perform seismic and short-circuit conditions.

These products are developed over the past experiences and high end technology for the manufacturing and quality tools.  Thus these are cost-efficient with long operating life, providing a platform for customer’s delight.
