An unarmoured power cable is a type of electrical cable designed to transmit power safely and efficiently without the added protection of metallic armour. It is commonly used in environments where the cable does not require heavy mechanical protection, such as indoor wiring, conduit systems, cable trays, or other controlled installations. Because it lacks an armour layer, this cable is generally lighter, more flexible, and easier to install than armoured alternatives.The basic structure of an unarmoured power cable usually includes one or more copper or aluminium conductors, insulation around each conductor, and an overall outer sheath for protection. The conductors carry electrical current, while the insulation prevents leakage and short circuits. The outer sheath helps protect the cable from moisture, dust, and general wear during normal use. Depending on the application, the cable may be designed for low, medium, or high voltage power distribution.One of the main advantages of an unarmoured power cable is its flexibility. Without the rigid metal armour, the cable can bend more easily, which makes it suitable for routing through tight spaces or complex installation paths. It is also typically more economical than armoured cable, both in material cost and installation labor. In many indoor and protected outdoor applications, this makes it a practical and efficient choice.Unarmoured power cables are widely used in buildings, commercial facilities, industrial equipment, control panels, and lighting systems. They are often installed in areas where there is little risk of mechanical damage. When used outdoors or underground, they usually need additional protection such as ducts, conduits, or buried installation methods with suitable safeguarding measures. Proper installation is important to ensure long service life and safe operation.These cables are manufactured in different sizes and specifications to meet various electrical requirements. The conductor size, insulation material, voltage rating, and temperature resistance can all vary depending on the intended use. Common insulation materials include PVC, XLPE, and other compounds that provide strong electrical and thermal performance. Some cables are also designed to resist flame propagation, heat, or chemicals.Although unarmoured power cables are not suitable for high-risk environments where physical damage is likely, they remain an important part of modern electrical systems. Their combination of simplicity, cost-effectiveness, and ease of handling makes them ideal for many standard power transmission applications. When selected correctly and installed according to the proper standards, an unarmoured power cable can provide reliable and long-lasting service in a wide range of settings.
