The working principle of a cabling machine is usually to drive the conductors or insulated cores on multiple pay-off racks through a rotating mechanism, twist them according to a predetermined twisting angle and direction, and finally form the required cable structure. During the cabling process, a braking device is used to maintain stable tension to prevent problems such as cable deformation, twisting or damage caused by tension fluctuations.
