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=0.21 at inductive voltage 100V/km) and are suitable for installation in high speed railway lines electrifi ed at 25KV ac.

Standards :

• SNCF CT 445
• NF F 55-698

 

Construction :

• Conductors : Solid annealed copper, 1.0 mm sq nominal cross section area.
• Insulation : Solid polyethylene.
• Cabling Element : Four conductors are twisted to form a quad.
• Stranding : Quads are helically stranded to get the cable core.
• Core Wrapping : Plastic tape(s) with overlapping.
• Inner Sheath : Low density polyethylene. LSZH FR option can be offered upon request to NF C 32 070.2.2 (C1).
• Electrostatic Shield : Corrugated copper tape.
• Intermediate Sheath : Low density polyethylene. LSZH FR option can be offered upon request to NF C 32 070.2.2 (C1).
• Electromagnetic Shield : Two helically applied steel tapes (0.5mm).
• Outer Sheath : PE/PVC compound. LSZH FR option can be offered upon request to NF C 32 070.2.2 (C1).
• Remarks : ZCO3: PE/PVC Sheath; ZCO3-SH: LSZH Sheath.
