Digicode 30KHz Indoor Signalling Cables

Application

The cables are designed for transmission of track circuit digicode signals up to 30 kHz in electrified lines.

Standard

  • 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)

Cable Construction

Digicode
  • 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.
