Traction Film Capacitors

Robust solutions for railway and transportation systems

Our traction film capacitors are designed for use in demanding transportation and railway environments where equipment must withstand vibration, thermal stress, and continuous duty cycles.

With designs adapted to harsh mechanical and environmental conditions, these capacitors support critical traction applications while helping maintain system stability and performance.

Typical applications:

  • Railway traction converters

  • Auxiliary power systems

  • Onboard power electronics

  • Transportation electrification systems

Segmentation to get protection

At CEFEM, using breakthrough technologies is part of our values. Segmented film is one of them.

Segmentation technology replaces the overpressure one.
Our film embeds fuses meaning that when a fault occurs, the outside circuitry will rush through the low resistance path created by the fault.
Consequently, the fault will heat and vaporize surrounding fault site. The amount of gas and the default will be limited to the area where the fault occurre

WHY CHOOSING SEGMENTATION?

  • Cheaper and Lighter
  • No Maintenance
  • Can be cast on in any way possible
  • More ecological
