3. Conductor stranding
In order to improve the softness of wires and cables and facilitate the laying and installation, the conductive core is made of multiple single wires. From the form of conductor core stranding, it can be divided into regular stranding and irregular stranding. Irregular stranding can be divided into bundle stranding, concentric compound stranding, special stranding, etc.
In order to reduce the occupied area of the conductor and the geometric size of the cable, the compact form is adopted while the conductor is twisted, so that the ordinary circle is changed into semicircle, fan-shaped, tile shaped and compact circle. This kind of conductor is mainly used in power cable.
