APPLICATION

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

STANDARD

  • RT/E/PS/00031

CABLE CONSTRUCTION

  • Type CodesConductors: Tinned copper, 0.9/1.4 mm nominal diameter.

  • Insulation: Solid polyethylene.

  • Cabling Element: Two insulated conductors are twisted together to form a pair.

  • Stranding: Pairs are helically stranded in concentric layers.

  • Filling: Cable core interstices are filled 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 (for S/B type): Polyethylene or LSZH fi re retardant compound.

  • Mechanical Protection (for S/B type): One corrugated steel tape or brass tape is longitudinally applied with overlap. Unarmoured cables option can be offered upon request.

  • 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: Unfi lled 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.
