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.
