WTB (Wired Train Bus) Cables
FRL-WTB-02YCH-2G0.75,FRL-WTB-02YCH-1P0.75S,FRL-WTB-02YCH-2P0.75S

Application :

  • The cables are designed for permanent installation inside of rolling stock to connect fixed parts. A typical application is a communication system in a locomotive. The system uses a wire backed bus system to the TCN standard for control and instrumentation and for diagnostics. This bus system consists of the rail bus WTB (Wired Train Bus) and the road bus MVB (Multifunction Vehicle Bus) which are connected via redundant gateways.

Construction :

  • Conductor Stranded tin plated copper conductor according to IEC 60228 class 5
    Insulation Foam PE or Foam Skin
    Core Wrapping Plastic tape(s)
    EMC Screen Tin plated copper braid
    Outer Sheath Cross-linked oil resistant LSZH compound
