In order to improve the flexibility of the power cord, in order to facilitate the laying of the device, the conductive core receives a plurality of monofilament strands. From the twisting manner of the conductive core, it can be divided into regular stranding and irregular stranding. Non-standard stranding is divided into beam stranding, core twisting, and extraordinary stranding. In order to reduce the occupied area of the wire and reduce the geometrical size of the power line, the twisted conductor is also pressed to make the common circular shape into a semicircle, a fan shape, a tile shape and a compact circular shape. This type of conductor is primarily used on power lines.
