What are the main types of armoured cables?

Common armoured cable types include SWA cable, AWA cable, STA cable, XLPE armoured cable, PVC armoured cable, LSZH armoured cable, low voltage armoured cable, medium voltage armoured cable, armoured control cable, and underground armoured power cable.
From a structure point of view, armoured cables are usually identified by the armour material and cable construction. SWA cable uses steel wire armour and is widely used for multi-core power cables requiring strong mechanical protection. AWA cable uses aluminium wire armour and is commonly used for single-core AC cables because aluminium is non-magnetic. STA cable uses steel tape armour and is often selected for fixed or buried applications where radial pressure or impact protection is important, but high tensile pulling force is not the main requirement. Technical comparisons often explain STA and SWA by their armour form: flat steel tape versus round steel wire.
