Armoured Cables are manufactured to BS-6346/IEC 60502 Standards. Typically, the construction of an Aluminium or steel wire armoured cable comprises six components: 

1. Conductor: This is usually a plain stranded Copper Conductor.
2. Insulation: Materials such as Poly-Vynyl Chloride (PVC) or Cross-linked Polyethylene (XLPE) provide good temperature resistance and excellent dielectric strength providing enhanced electrical properties.
3. Bedding: This is a layer to create a protective barrier between armour and insulation.
4. Armour: A steel or aluminium armour provides mechanical protection to allow the cable to withstand the mechanical stresses to which it is exposed.
5. Sheath: the constituent parts of the cable are held together by a sheath offering a further level of protection. Black Poly-Vinyl Chloride sheaths can be carbon-loaded for UV stability.
6. Voltage: Voltage ratings of 600/1000V, 6.35/11kV and 19/33kV
