CV/CVZ Indoor Equipment Cables
Application
The cables are used as cabling wires for the relays and electronic equipments in the Traffic Control Center and Trackside Equipment Shelter. The CV cables are suitable for use only in Optical Control Panel (OCP) wiring.
Standard
Cable 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 mm cross section.
- Insulation: White (for CVZ type)/coloured (for CV type) unleaded PVC.
- Sheath: Coloured polyamide outer sheath (for CVZ & CVZ-S type).
