What are the advantages and limitations of armoured cables?

The main advantage of armoured cables is strong mechanical protection. The armour layer helps protect the cable from impact, crushing, penetration, accidental damage, and pulling stress during installation. This makes armoured cables suitable for construction sites, factories, outdoor installations, underground routes, and other demanding environments.
Armoured cables may also reduce the need for extra mechanical protection in some installations, depending on local rules and project design. However, they are usually heavier, less flexible, larger in diameter, and more costly than non-armoured cables. They also require proper cable glands, earthing or bonding, bending radius control, and qualified installation.
Professional armoured cable guides often group the benefits around mechanical protection, durability, safety, and suitability for industrial, infrastructure, public building, and renewable energy installations.
