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.
