RT/F3 D & S & B type Axle Counter Cable

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

RT/E/PS/00031

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.

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.
