6mm 3 Core SWA Armoured Cable – Heavy-Duty Steel Wire Protection for Underground and Outdoor Power
Looking for a reliable, high-performance cable for underground or external installations? 6mm 3 Core Steel Wire Armoured (SWA) Cable is a robust solution, designed to carry mains electricity in residential, commercial, and industrial applications. It features a tough black PVC sheath, cross-linked polyethylene (XLPE) insulation, and stranded copper conductors with a galvanized steel wire armour for maximum mechanical protection.
📌 Key Applications
- Direct burial in the ground (resistant to mechanical damage)
- Outdoor electrical supply and lighting
- Incoming mains for homes and commercial properties
- Industrial power distribution networks
The XLPE insulation resists chemicals, oils, and UV exposure, making this cable suitable for harsh environments.
