70mm 4 Core Armoured Cable is a size and type of steel wire armoured cable. Primarily found in large powered networks and underneath roadways supplying mains electricity to large buildings. It can also be found within the transport industry, specifically railways powering the trains and buildings located beside the tracks. Due to the size of this cable, it is perfectly suitable for large amounts of power running through it on a daily basis, 24 hours a day.
The best solution to this issue would be to buy a length of earth cable that matches the length of the Armoured Cable. This would negate the steel wire from being used as an earth, meaning it is a safer alternative.
70mm 4 Core Armoured Cable is constructed from the following materials;
– Plain Annealed Stranded Copper for the cores
– Cross-Linked Polyethylene for the Insulation
– PVC (Polyvinyl Chloride) for the bedding and sheathing
