4 Core Armoured Cable is commonly found supplying mains voltage electricity to powered devices and networks. For example, it could be used to power outdoor buildings such as garden sheds or workshops as well as garden features such as hot tubs.The cable contains a steel wire armour, meaning it provides a mechanical protection for the insulating layers underneath. This also enables the cable to have higher pulling loads, making it perfectly suitable for dispensing from a cable drum on a building site, etc.
It's construction is commonly identified by the plain annealed stranded copper for the cores, the PVC(Polyvinyl Chloride) for the bedding and sheathing, armour made from steel wire and XLPE(Cross-Linked Polyethylene) for the insulation.The Steel Wire can also be used as a CPC(Circuit Protective Conductor), meaning the armour can be used an earth for the cable.This means that even though the cable has an earth core, it is still protected, meaning it abides by all health and for safety
