ZPFU & ZPFU-SH Main & Local Signalling Cables

 

Applications :

  • ZPFU & ZPFU-SH Main & Local Signalling Cables (Ordinary Non-Electrified or DC Electrified Lines).
  • The cables are designed for the main signalling circuits of 1500V DC electrifi ed lines.

Standards :

  • SNCF CT 445
  • NF F 55-698
 

 

Construction :

  • Conductors : Solid annealed copper, 1.0mm sq nominal cross section area.
  • Insulation : Solid polyethylene.
  • Cabling Element : Two conductors are twisted to form a pair.
  • Stranding : Pairs are helically stranded to form the cable core.
  • Core Wrapping : Plastic tape(s) with overlapping.
  • Inner Sheath : PE. LSZH FR option can be offered upon request to NF C 32 070.2.2 (C1).
  • Mechanical Protection : Two helically applied steel tapes (0.15, 0.2/0.5mm, depending on pair count).
  • Outer Sheath : PE/PVC. LSZH FR option can be offered upon request to NF C 32 070.2.2 (C1).
  • Remarks : ZPAU: PE/PVC Sheath; ZPFU-SH: LSZH Sheath.
