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

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

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: 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.
