A 70mm2 4-core armoured cable is a medium-to-heavy duty power cable widely used in Nigeria for reliable three-phase electrical distribution in homes, estates, and industrial setups.
This cable has four copper conductors, each with a 70mm2 cross-sectional area, protected by insulation and a steel armoured layer. It is ideal for carrying high electrical loads safely over long distances.
Construction
1. Conductors 4 cores (Red, Yellow, Blue – phases + Neutral) Made of pure copper for efficient conductivity
2.Insulation PVC or XLPE insulation on each Prevents leakage and short circuit
3.Bedding Layer Inner protective layer to support the cores
4.Armouring (SWA – Steel Wire Armour) Steel wire
