Effilight traction transformer

ABB’s Effilight®  traction transformer is a next generation traction transformer that reduces the weight of on-board components and ensures more energy-efficient rail networks, two of the rail industry’s priority objectives.

Traditionally made of iron and copper, traction transformers are among the heavier components on a train. They use oil for insulation and cooling, for its excellent electrical insulating properties and high reliability.

Effilight uses a unique and patented high-technology cell design that reduces the amount of oil needed by up to 70 percent, without compromising functionality. The technology enables unprecedented weight reduction (up to 20%)  and energy savings (up to 50%) for train manufacturers and rail operators.

  • Available for 15 kV and 25 kV
  • Available in steel or aluminum tank
  • Appropriate for retrofit and new train platform
