Intercity railway signal cable ZPFU

ZPFU

Intercity railway signal cable (DC-electrified lines)

Benefits

  • Can be used in short lengths along 25kV AC-electrified tracks to connect switchgear substations to switches and crossings

Applications

  • Connects the central control station to the switchgear substations
  • Installed in long lengths along non-electrified tracks and 1500V DC-electrified tracks
