What should customers consider before selecting armoured cable?

Customers should consider the installation environment, voltage rating, conductor material, number of cores, armour type, sheath material, fire performance, mechanical stress, bending radius, cable route, earthing method, and local electrical regulations.
For underground or direct burial installation, customers should check whether the cable needs additional moisture protection, ducting, warning tape, sand bedding, or stronger mechanical protection. For indoor public areas, LSZH sheath may be more suitable than PVC. For single-core AC systems, AWA is usually more appropriate than SWA. For installation, the cable should not be bent below the manufacturer’s recommended minimum bending radius, because excessive bending can damage the insulation, sheath, or armour layer. Installation guidance for SWA cables emphasizes respecting minimum bending radius and avoiding sharp bends during routing.
