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.
