Armoured cable refers to the cable with a metal material armor protective layer, the purpose of the cable plus the armor layer is not only to enhance tensile strength, compressive strength and other mechanical protection to extend the service life, but also through shielding protection to improve the cable anti-interference performance.
Commonly used armor materials are steel belt, steel wire, aluminum strip, aluminum tube, etc., of which steel belt, steel wire armor layer has high magnetic permeability, has a good magnetic shielding effect, can be used to resist low-frequency interference, and can make the armored cable directly buried and laid without piercing the pipe and cheap and high quality in practical use.
Different specifications and different numbers of copper wires in a certain order and stranded together, it becomes a larger diameter conductor, this twisted large diameter stranded conductor is softer than the same diameter size of single copper wire, the wire bending performance is good, swing test is not easy to break, for some soft wire (such as medical grade wire) is easier to meet the requirements.
From the electrical performance point of view: after the conductor is energized, it heats up due to the resistance to consume electrical energy. As the temperature rises, it will affect the material performance life of the insulation layer and protective layer. In order to make the cable run efficiently, the conductor section should be increased, but the large section of a single conductor is not easy to bend, the flexibility is poor, which is not conducive to production, transportation and installation and laying. From the mechanical properties, it is required to have flexibility, reliability, and multiple single wires twisted together to solve the contradiction.
