5 Core SWA BS5467 - 4mm - CablelandA 4mm2 5-core cable is a heavy-duty, multi-conductor electrical cable designed for 3-phase power distribution, controls, and machinery, capable of handling higher current loads. It typically features five copper conductors black, blue, brown, grey, and green/yellow) shielded by XLPE ,PVC insulation, commonly armoured for direct burial.
Construction: Typically copper conductors, XLPE insulation, PVC bedding, steel wire armour (SWA), and a black PVC outer sheath.
Current Rating: Roughly 30A-35A, depending on installation methods.
Voltage Rating: Often 600/1000V (for SWA) or 300/500V (for control cabling).
Core Colours: Brown, Black, Grey, Blue, and Green/Yellow.
