A 6mm2 3-core armoured cable in Nigeria is a durable low-voltage power cable designed for three-phase or single-phase power distribution where extra mechanical protection is needed.
Construction
The cable is made up of the following parts:
* Conductors: Copper or aluminium (for efficient current flow)
* Cores: 3 cores (typically Live, Neutral, and Earth or for 3-phase systems)
* Insulation: PVC or XLPE (heat-resistant and durable)
* Armouring: Steel Wire Armour (SWA) for mechanical protection
* Outer Sheath: PVC (black, weatherproof and corrosion-resistant)
Electrical Rating
* Voltage rating: 0.6/1kV (standard for low-voltage distribution)
* Current capacity: Approx. 30–50 amps depending on installation method (buried, clipped, or in conduit)
