UNITRONIC® TRAIN
Bus cables – MVB and WTB – Electron beam cross-linked for high requirements in railway applications
- Small outer diameters for maximum saving of space and weight
- Extremely low attenuation ≤ 5 MHz
Benefits
- Good chemical resistance
- Resistant to mechanical influences in harsh environmental conditions
- Extended temperature range
- Reduced flame spreading increase the protection against damage to persons and property in the event of a fire
- EMC-optimised design
Application range
- The communication systems WTB (wire train bus) and MVB (multifunction vehicle bus) make up the so-called TCN (train communication network)
- UNITRONIC® TRAIN bus cables are designed for use in TCN acc. IEC 61375
MVB according IEC 61375-3-1
WTB according IEC 61375-2-1 - For use in railway vehicles and buses, for fixed installations and applications where limited movement may occur
- Also applicable within oily environments and areas with increased ambient temperature
