MVB (Multifunction Vehicle Bus) Cables (Redundant Version)

 

Applications :

  • The cables are designed for permanent installation inside of rolling stock to connect fixed parts. A typical application is a communication system in a ocomotive. 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.

Standards :

  • DIN 5510-2
 

 

Construction :

  • Conductors : Stranded tinned copper conductor according to IEC 60228 class 5.
  • Insulation : Foam skin-composite PE made of inner cellular layer and outer solid skin.
  • Core Wrapping : Plastic tape(s).
  • EMC Screen : Tinned copper braid.
  • Outer Sheath : Cross-linked oil resistant LSZH compound.

Electrical Characteristics at 20 °C :

  • Nominal Cross Section mm² 0.5
    Maximum Conductor Resistance Ω/km 41
    Impedance@0.75-3MHz Ω 120+/-12
    Maximum Attenuation @1.5MHz dB/km 17
    Maximum Attenuation @3MHz dB/km 25
    Maximum Transfer Impedance mΩ/m 20
    Nominal Voltage Rating V 300

Mechanical and Thermal Properties :

  • Minimum Bending Radius : 6×OD (single); 10×OD (multiple).
  • Temperature Range : -40°C to +100°C (during operation); -20°C +50°C (during installation).
