What Are Armoured Cables?

November 3rd, 2021

Cable armour is typically a helically wrapped bundle of wire elements immediately beneath the cable’s outer sheath, but in some constructions may take the form of a mesh or braid. Armour material is usually steel (SWA), but aluminium (AWA) is often used in single core cables to prevent current induction within the armour itself. Armouring a cable affords it greater protection from mechanical stress and provides higher tolerance to pulling loads.

Superlec Direct’s range of armoured cables are sheathed in either PVC (Polyvinyl Chloride) or LSZH (Low Smoke Zero Halogen), with bedding, insulation, and shielding materials according to the appropriate cable standard. Core sizes range from 1.5mm 2 upwards, with copper or aluminium conductors. Common core configurations (such as single core, or 3 core) are typically held in stock for immediate dispatch.

Armoured cables are generally used in power networks, and are suitable for installation underground or within cable ducting. Domestically, armoured cables are an excellent choice for supplying power to:

  • Electric vehicle charging points
  • Hot tubs
  • Gardens and outdoor lighting
  • Shed electrics
  • Pond pumps
