MVB (Multifunction Vehicle Bus) Cables
Applications :
- The cables are designed for transmission of digital signals under baud rate of 10M inside of rolling stock to connect fi xed parts. The communication system in a locomotive 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 5510-1
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.
