RT/F3 E1/E2/E3 Type Axle Counter Cable

 

Applications :

  • The cables are designed for transmission of signals up to 90 kHz in axle counter train detection systems.

Standards :

  • RT/E/PS/00031
 

 

Construction :

  • Conductors : Tinned copper wire, 0.9 or 1.4 mm nominal diameter.
  • Insulation : Solid polyethylene.
  • Cabl ing Element : Two insulated conductors are twisted together to form a pair.
  • Stranding : Pairs are helically stranded in concentric layers.
  • Filling : Cable core interstices are fi lled with a low-permitivity compound. Unfi lled cables option can be offered upon request.
  • Core Wrapping : Plastic tape(s) with overlapping.
  • Moisture Barrier: One laminated sheath made of aluminium tape coated with PE-Copolymer on at least one side is applied with longitudinally overlap.
  • Inner Sheath : Polyethylene or LSZH fi re retardant compound.
  • Electrostatic Shield : One layer of helically applied copper wires.
  • Electromagnetic Shield : Two helically applied steel tapes.
  • Outer Sheath : Polyethylene or LSZH fi re retardant compound. Ruggedised PE sheath compound can be offered upon request.

  • F1 class : Non LSZH cables.  
    F5 class : Unfilled cables
    D type Unarmoured types
    R type : Ruggedised PE sheath
    S type : Steel tape armoured types
    B type : Brass tape armoured types
    E1, E2 & E3 types : 3 different induction protection levels available.
