ZCO3 Main Signalling Cables (AC Electrified High Speed Lines)
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.
