Application
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. 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 PECopolymer 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.
Type Codes
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.
