4x35mm2 armoured cable (typically CU/XLPE/SWA/PVC) is a 4-core low-voltage power cable with 35mm2 copper conductors, cross-linked polyethylene insulation, steel wire armour (SWA), and PVC sheath. It supports high loads (~150A) and is ideal for industrial power networks, direct burial, and underground, outdoor, or indoor, moisture-prone installations
