ZPAU Signal cables

ZPAU

Intercity railway signal cable (LGV and AC-electrified lines)

Benefits

  • Protected against electromagnetic parasitic induction of the overhead line
  • Anti-rodent
     

Applications

  • Links the centralised control station to the switchgear substations
  • Installed in long lengths along 25,000V AC-electrified tracks
