Cable for moving arm of robot

The invention discloses a cable for a moving arm of a robot. The cable comprises a cable core layer, an inner shielding layer, an outer shielding layer, an inner sheath layer and an outer sheath layer in sequential arrangement from inside to outside. The cable core layer is formed by back-twist stranding of a plurality of control wire cores, a plurality of twisted pairs, a plurality of ground wire cores and a plurality of tension fill wire cores. The cable for the moving arm of the robot is simple in structure and low in cost; by addition of the tension fill wire cores, flexibility and resistance to bending, interference and torsion of the cable are guaranteed while tension resistance of the cable is greatly improved, and practical utilization requirements of the moving arm of the robot can be met to the greatest extent.
