RAILDATA Databus Cables For Railway Applications

MVB (Multifunction Vehicle Bus) Cables

 

 

Application

MVB (Multifunction Vehicle Bus) 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.

Construction

Conductors: Stranded tinned copper conductor according to IEC 60228 class 5.

Insulation: 0.6mm foam/foam sk in P E (for 0. 5sqm m cond uctor ), 0. 2mm PE ( for 0.25sqmm conductor).

Core Wrapping: Plastic tape(s).

EMC Screen: Tinned copper braid.

Outer Sheath: Cross-linked oil resistant LSZH compound.
