Applications :

• The cables are designed for connection between traffi c control centers and equipment shelters along the trackside. The cables are specially designed to give good induction protection (R.F= 0.26 at inductive voltage 100V/km) and are suitable for installation in intercity railways electrifi ed at 25KV ac.

Standards :

• SNCF CT 445/SNCT ST 698G
• NF F 55-698

 

Construction :

• Conductors : Solid annealed copper, 1.0/1.5 mm sq nominal cross section area.
• Insulation : Solid polyethylene.
• Cabling Element : Each two conductors are twisted together to form a pair.
• Stranding : Pairs are helically stranded in layers to form the cable core.
• Core Wrapping : Plastic tape(s) with overlapping.
• Inner Sheath : PE sheath. LSZH FR option can be offered upon request to NF C 32 070.2.2 (C1).
• Electrostatic Shield : One corrugated copper tape.
• Intermediate Sheath : PE/PVC sheath. LSZH FR option can be offered upon request to NF C 32 070.2.2 (C1).
• Electromagnetic Shield : Two helically applied steel tapes of 0.5mm.
• Outer Sheath : PE/PVC compound. LSZH FR option can be offered upon request to NF C 32 070.2.2 (C1).
• Remarks : ZPAU: PE/PVC Sheath; ZPAU-SH: LSZH Sheath.
