The conductor’s insulation is usually a polymer such as PVC or XLPE. The armoured wire size (cross-section) of the conductor can be varied to suit the application, but the most common sizes are 16mm armoured cable, 25mm armored cable, and 35mm 4 core swa.Īrmoured cable 10mm requires a smaller conductor than 16mm armoured cable as the armoured layer takes up more space, whereas the 6mm swa cablecan have a smaller conductor. The conductor of the armour cable is usually made from stranded copper or aluminium. Different armored electrical cables, including aluminum armoured cable and copper armouredcable, consist of the following components in their construction. The armoured cable is manufactured with a range of cores such as 2 core armoured cable, 3 core armoured cable, 4 core armoured cable, and even up to 36 cores. But, adding the armoured layer or layers makes it suitable for more hazardous applications. There are various armored cable cable types but most common type used today is steel wire armouring (SWA), a galvanized steel wire braid surrounding the inner sheath of the cable.Īrmored cable construction is not much different from other types of power cable. The construction is similar, whether it’s a SWA armored cable or PVC armoured wire. Let’s dive in and learn more about the armour cable. Furthermore, armour cable is characterized by strong anti-corrosion performance because of the good material selection. The armoured power cablemainly applied to railways, subways, high buildings, and other special occasions.Īs the name suggests, armored cable has a protective layer, which can protect the inner wire of armour cable and ensure the safety of workers. The armouredcable can have better mechanical strength, which can resist external forces, so it is suitable to be laid in various complex environments. Armour cable is an electrical cable specifically designed for use in potentially hazardous areas. We offer a comprehensive range of BASEC-approved armoured cables, manufactured in accordance with a number of British, European and International standards including BS5467, BS6622, BS6724, BS7835, BS EN 50267, IEC 60502 and BS EN 6 (for single core cables).Įland Cables' range of armoured cable is available with a Copper (Cu) or Aluminium (Al) conductor and with a Polyvinyl Chloride (PVC) or Low Smoke Zero Halogen (LSZH) sheathing, LSZH sheathings are recommended for use in high density enclosed areas, and are mandatory in some public places.With the development of the power industry and modern technology, the armoured cable is increasingly widely used for long-distance transmission projects of direct or alternate current. The construction of our various types of armoured cable (US spelling armored cable) differs according to their intended application and may also include steel tapes, protective screens and materials suited specifically to the installation conditions. Black sheaths can be carbon-loaded for UV stability. Sheath: the constituent parts of the cable are held together by a sheath offering a further level of protection. Insulation: materials such as cross-linked polyethylene (XLPE) provide high temperature resistance and excellent dielectric strength-providing enhanced electrical properties.īedding: a layer to create a protective barrier between the insulation and the armour.Īrmour: a steel or aluminium armour provides mechanical protection to allow the cable to withstand the mechanical stresses to which it is exposed. Typically, the construction of an aluminium or steel wire armored cable comprises six components:Ĭonductor: plain stranded copper or aluminium
