Armoured cable description.

Armoured cable description.

• A. It has no protective armour
• B. It is used only indoors
• C. It uses plastic armour
• D. It has metallic armour for mechanical protection and is used in outdoor or harsh environments

Answer: (D)

Armoured cable is built with a metallic layer around the insulation to provide mechanical protection for the conductors. That metal armour shields the wires from impacts, abrasion, and other physical damage, which is essential in outdoor or harsh environments, including underground runs or areas with exposed equipment. The armour is typically steel (wire or tape) and is often bonded to earth for safety in some installations. Because of this metal protection, the description that there is no armour, that it’s used only indoors, or that it uses plastic armour isn’t accurate.
