K23

Signalling
Urban railways (underground networks)

Benefits

  • International benchmark for tunnel cables
  • Exceptional fire performance and mechanical properties

Applications

 

  • Main cable for signal, remote control and remote transmission, installed in ducts, cable trays or on hooks
  • Halogen-free cable, laid along electrified underground lines up to 1500VCC
  • Intended use: metro
  • Other possible uses: tunnel or underground sections of the Regional Express Network and Tramway
     

General characteristics
