More than half the world’s electrical locomotives and train sets are powered by Hitachi ABB Power Grids transformers, and the vast majority of the world’s train manufacturers and rail operators rely on them.
Hitachi ABB Power Grids's traction transformers are integral to this capability. Their function is to transfer electric power from the catenary to the motor by lowering the network’s high voltage to low voltage for use by the converters. They have to be compact, lightweight and exceptionally reliable, as they are often a non-redundant traction component.
Engineered for very harsh and demanding environments, the transformers are designed to power heavy freight loads over long distances of more than 1,000 km and on tracks with many challenges - steep profiles, short curve radii, excessive wear, voltage drops in long sections, and extreme low and high temperatures.
