RAILDATA Databus Cables For Railway Applications

MVB (Multifunction Vehicle Bus) Cables (Redundant Version)

Application

MVB (Multifunction Vehicle Bus) Cables (Redundant Version) 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

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.

Standards

DIN 5510-2
