Digicode 30KHz Indoor Signalling Cables
Applications :
- The cables are designed for transmission of track circuit digicode signals up to 30 kHz in electrifi ed lines.
Standards :
- EN 50266-2-4 & IEC 60332-3(Fire performance)
- EN 50268-2(Smoke density)
- EN 50267-2-1(Halogen content)
- EN 50267-2-2(Gases acidity)
- EN 50265-2-1, IEC 60332-1, NF
- C 32070 Cat C2 compliant (for PVC sheathed cables)
Construction :
- Conductors : Solid Annealed copper, 1.4 mm nominal diameter (0.6 mm for the auxiliary pair).
- Insulation : Polyethylene.
- Cabling Element : Two insulated conductors are twisted together to form a pair.
- Stranding : Pairs are helically stranded to get the cable core.
- Core Wrapping : Plastic tape(s) with overlapping.
- Inner Sheath : Low density polyethylene.
- Moisture Barrier : Copolymer coated laminated aluminium tape.
- Intermediate Sheath : LSZH fi re retardant compound. PE or PVC option can be offered upon request.
- Mechanical Protection : Two helically applied steel tapes.
- Outer Sheath : LSZH fi re retardant compound. PE or PVC option can be offered upon request.
