SANS 1507 CNE Concentric Cable
Application
Aerial CNE Cable is used for house connections. This cable can only be used for single-phase power supply. Cables are for hanging in the air. Aerial CNE Cable is also suitable for general underground use. Split concentric cable is suitable for underground or overhead distribution cables.
Benefits
Small overall diameter - concentric construction
Lower mass - due to smaller diameter - no steel wire armor
Increased safety - reliable earthing
Improved reliability - UV stable sheath and core insulation
Tamper and vandal proof - unauthorized access to phase conductor inhibited by concentric layer
Easy strip with nylon ripcord
Standard
SANS 1507-6--- Electric cables with extruded solid dielectric insulation for fixed installations (300/500 V to 1 900/3 300 V) Part 6: Service cables.
Construction
Stranded hard drawn copper phase conductor, XLPE insulated with bare/neutral earth conductors. Polyethylene sheathed house service cable. Nylon ripcord laid under sheath.
