Axle Counter Cable
RT/F3 D & S & B 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, 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. Unfilled 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 fire 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 fire retardant compound. Ruggedised PE sheath compound can be offered upon request.
Type Codes
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.
