Core aluminum armoured cable is a robust power transmission and distribution cable designed for fixed installations where mechanical protection, reliability, and cost-efficiency are required. It is commonly used in industrial plants, commercial complexes, infrastructure projects, and utility networks to supply electricity to equipment, lighting systems, and power distribution boards.The conductor is made of high‑purity aluminum, either solid or stranded, to achieve a balance between electrical performance and mechanical flexibility. Aluminum offers a lighter weight and lower material cost compared with copper, making it suitable for long runs and large cross-sectional sizes where overall cable weight is a critical factor. Although aluminum has higher electrical resistance than copper, this is compensated by selecting an appropriate conductor size to achieve the desired current‑carrying capacity and acceptable voltage drop.Each core is insulated with a high‑grade polymer such as cross‑linked polyethylene (XLPE) or PVC. XLPE insulation provides excellent thermal stability, higher operating temperature, and good resistance to aging, chemicals, and moisture. The insulation is typically color‑coded or numbered to allow easy phase identification during installation and maintenance.A key feature of this cable type is the metallic armouring layer. Around the insulated cores, steel wire armour (SWA) or aluminum wire armour (AWA) is applied, depending on the application and fault current requirements. The armour serves as a mechanical shield, protecting the cable from impact, crushing forces, and accidental damage during and after installation. It also provides additional protection against rodent attack and can be used as an earth or fault return path when designed for that purpose. This makes the cable suitable for direct burial in the ground, installation in ducts, or laying in areas exposed to potential mechanical stress.Over the armour, an outer sheath made of durable PVC or polyethylene is extruded. The sheath protects against moisture, UV radiation, chemicals, and general environmental effects. For outdoor and underground installations, the sheath is formulated to resist abrasion and degradation over long service life.Core aluminum armoured cable is manufactured in various core configurations, such as 2‑core, 3‑core, 3.5‑core, and 4‑core, to meet different system requirements, including single‑phase and three‑phase networks with or without a dedicated neutral conductor. It is rated for different voltage classes, typically up to 0.6/1 kV for low‑voltage applications, and designed to comply with international standards governing conductor quality, insulation performance, flame retardance, and overall safety.Installation can be carried out in trays, on cable ladders, on walls, or directly underground, following applicable regulations and recommended bending radii, pulling tensions, and termination methods. Because of its combination of mechanical strength, electrical performance, and economic advantages, core aluminum armoured cable is widely adopted as a reliable solution for demanding power distribution environments.
