Conductor: plain stranded copper or aluminium
Insulation: a crossed-linked polyethylene (XLPE) insulation provides thermal stability, good water resistant qualities and excellent electrical properties.
Bedding: polyvinyl chloride (PVC) is employed in order to create a protective barrier between the inner and outer layers of the cable.
Armour: a steel or aluminium armour (SWA / AWA) provides mechanical protection to allow the cable to withstand the mechanical stresses to which it is exposed.
Sheath: the constituent parts of the cable are held together in a black PVC sheath offering a further level of protection. Black sheaths can be carbon loaded for UV stability.
Voltage: voltage ratings of 0.6/1kV, 6.35/11kV and 19/33kV
