EUROBALISE SIF

 

Applications :

  • The cables are used in Eurobalise (ERTMS) speed control circuits. The cables are laid in trays alongside railway lines and connect an “Eurobalise” located between the rails to the Eurocoder (LEU) located in a control centre.

Standards :

  • ALSTOM 5 326 203
  • SNCF CT 446
 

 

Construction :

  • Conductors : Class 2 stranded copper.
  • Insulation : Solid polyethylene.
  • Inner sheath : Low density polyethylene.
  • Screen : Two corrugated copper braid shields.
  • Intermediate Sheath : Low density polyethylene.
  • Armour : Galvanized steel braid armour.
  • Outer Sheath : Flame Retardant PVC.
