In a stranding system, the cores of a cable are twisted together. The system connects the cores to form a compact strand which makes these cores and the cable robust and flexible for the respective application, e.g. in a robotic energy supply system. For maximum mobility, the stranded cores are finally wrapped in fleece or foil. The stranding can take place e.g. as pair stranding or as star-four stranding. At the end, a different cable is produced depending on the number of stranded cores.
