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.
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.
