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.

SNCF CT 445

NF F 55-698

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).

Remark : ZPFU : PE/PVC Sheath; ZPFU-SH : LSZH Sheath.
