EUROBALISE SIF
Application
EUROBALISE SIF 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.
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.
Reference Standards
ALSTOM 5 326 203
SNCF CT 446
