Application
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, 1.0mm² 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
ZPFU: PE/PVC Sheath; ZPFU-SH: LSZH Sheath.
