Cu/XLPE/PVC/SWA/PVC

Uo/U  - 0.6/1 kV BS 5467-1997
The power and control cables with cross-linked polyethylene (XLPE) armored with galvanized steel wires are used in electrical installations with nominal voltage Uo/U 0.6/1 kV. These cables are used in industrial installations and urban networks.
 
These cables are for fixed assembly in lines with unlimited difference levels, for laying in industrial installations, in cable ducts, tunnels and conduits, over shelves and grilles outdoor under shelters.
