CV /CVZ Indoor Equipment Cables
Application
The cables are used as cabling wires for the relays and electronic equipments in the Traffi c Control Center and Trackside Equipment Shelter. The CV cables are suitable for use only in Optical Control Panel (OCP) wiring.
Standards
- SNCF CT 500
Construction
- Conductors: Class 5 stranded tinned copper (for flexible wires CV-S & CVZ-S type), class 1 solid tinned copper (for stiff wires CV & CVZ), 0.5/1.0/2.5/6.0 mm² cross section.
- Insulation: White (for CVZ type)/coloured (for CV type) unleaded PVC.
- Sheath: Coloured polyamide outer sheath (for CVZ & CVZ-S type).
