With a solid, proven background in the transformers industry dating back to 1920, Alstom is a leading player on the onboard traction transformers, supporting train manufacturers and operators worldwide. Alstom’s Mitrac Transformer™ is developed with eco-design principles, leading to savings on energy consumption, weight and volume, and keeping maintenance needs at a minimum.
-
Efficiency and sustainability as main drivers
Alstom’s technology solutions are based on eco-design principles, leading to higher energy efficiency, improved mean-time between failures (MTBF), low noise and reduced lifecycle costs. As an example, the naturally-cooled transformer developed by Alstom for regional rail application eliminates the need for fans needed as the air flow originating from the train’s speed is directed towards the radiators, which significantly reduces total cost of ownership. In addition, Alstom’s transformers are highly recyclable, as a way to limit the environmental impact of its products.
-
A wide range of applications
With its transformers, Alstom covers all types of rolling stock – from locomotives, light-rail vehicles, metros, commuter, regional and high-speed trains – with a great variety of designs and installations available. Thanks to Alstom’s standardisation approach, its products meet both Alstom and non-Alstom car builders’ requirements, ensuring a highly reliable, cost effective and efficient solution.
-
Engineering and manufacturing
With the most up-to-date simulation, validation and testing tools, and stringent validation procedures, Alstom ensures that customers receive the latest proven technology to power all trains regardless of the manufacturer. Its products comply with the latest railway norms and standards. Benefitting from the most recent manufacturing equipment and a highly-skilled workforce, in combination with thorough purchasing and quality policies, Alstom is able to deliver high-quality and ultramodern products.
