    MVB (Multifunction Vehicle Bus) Cables

    FRL-MVB-02YCH-1P0.5S+1G0.5 , FRL-MVB-02YCH-2P0.5S

    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 tinned copper conductor according to IEC 60228 class 5
    Insulation Foam PE or foam skin PE
    Core Wrapping Plastic tape(s)
    EMC Screen Tinned copper braid
    Outer Sheath Cross-linked oil resistant LSZH compound

    Electrical & Mechanical Properties

    Nominal Voltage 300V
    Maximum Temperature 90°C
    Minimum Temperature -40°C
    Bending Radius 10 x Overall Diameter
