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.
