TWISTING MACHINES

Twisting machines are one of the most important stages of cable production.

Core twisting is used to reduce mutual electromagnetic influences. It also reduces the influence of external electromagnetic fields on cable circuits, facilitates the mutual movement of cores during cable bends and provides it with a more stable and round shape. The cores in stranded cables are twisted in concentric coils (layers), adjacent layers in opposite directions. Insulated cores are twisted into groups in several ways.

Simple cable twisting is used only in multicore cables consisting of identical insulated cores used in single-wire circuits. In this case, the cores are laid in concentric layers or by layers around the central core.

Complex cable twisting is performed from previously twisted cores into elementary groups of symmetrical cables.
