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.
