In our daily life, armored wire and industrial cable are playing a key role and they could even be called lifesavers of our modern lives.
Armored Wire Cable
As the name suggests, armored cables have added protective armor that helps protect the cable cores.
This is important because cables can be accidentally damaged by mechanical stress or impact.
To summarize, armored cables are often used when you have to bury cables directly underground, in outdoor installations, or in tunnels.
There may be situations where the ground is reopened, and in this connection, a shovel or mechanical excavator may accidentally hit a buried cable.
In this case, the armor will help protect the cable conductor core from being easily exposed and prevent electric shock and interruption of the power supply.
Armored Wire Cable Features
If a single-conductor cable is paired with steel wire armour, a magnetic field is generated when current flows - the entire cable becomes a large magnet.
The greater the current, the greater the magnetic field.

Magnetic fields induce currents (eddy currents) in the steel, which can lead to overheating and severe derating of the cable.
Aluminum does not cause this problem due to its non-magnetic properties.
But once we change the single-core wire to two or more cores, it is safe to return to the galvanized steel wire armoring, since the magnetic field created in this multi-core cable is canceled by the magnetic field of the other core wire, prevent the magnetic flux.

Armored electrical cables are essentially reinforced cables.
It's basically stronger than regular power cables.
Common belief holds that only Steel Wire Armored (SWA) cables are protected by armor.
But contrary to common thought, armored cables come in a number of different types.
Cables can be protected by either aluminum or steel wire armor.
For single-phase circuits that require earth connections, three-core steel wire armored cable is the most common choice.
Steel-armored four-core cable is ideal for use in TP&N three-phase and earth systems.

When using armored cables, it is important to provide adequate support so that the gland termination does not bear the full force of the cable.
The risk of wires breaking under the strain of their own weight can be reduced by giving them a sturdy base to rest on.
Because of the prevalence of armored wires terminated in housings, this is becoming increasingly important.
The price is between $1 to $27 per meter.
Since connections of this type must offer mechanical robustness and electrical continuity, it is essential to use the right armored cable gland to terminate the armoring.
