Abstract

The invention provides a high-weather-resistant, torsion-resistant and bending-resistant control cable, and relates to the technical field of design of towline cables. The high-weather-resistant, torsion-resistant and bending-resistant control cable includes a cable core formed by mutual twisting of a plurality of reinforced insulating wire cores, an inner liner layer, a reinforced braided shielding layer and an outer sheath layer are arranged in sequence outside the cable core, each reinforced insulating wire core includes a conductor externally wrapped by an insulating layer, and the conductor is formed by intertwisting copper wires and Dupont fibers in the same direction; and the reinforced braided shielding layer is formed by braiding copper wires and Dupont fibers in a combined manner, each spindle of copper wires is provided with a piece of Dupont fiber, and the braiding density of the reinforced braided shielding layer is larger than 90%. The high-weather-resistant, torsion-resistant and bending-resistant control cable provided by the invention has the characteristics of excellent interference resistance, torsion resistance, bending resistance and the like, and can meet market requirements.

Description

technical field [0001] The invention relates to the technical field of design of towline cables. Background technique [0002] With the rapid development of industrial automation systems such as industrial electronic drag chain systems, automated production line drag chain systems, logistics transmission equipment drag chain systems, and CNC machine tool drag chain systems, the requirements for supporting drag chain cables are getting higher and higher, especially for automation High-level industrial robots, some equipment have high frequency of movement and wide operating range, which requires that the supporting cables should have the characteristics of drag resistance, wear resistance, winding resistance, bending resistance, and torsion resistance. The flexibility, flexibility, and tensile strength of the cable are required to be high. Existing towline cables are prone to accidents such as sheath wrinkling and deformation, shielding layer copper wire breaking, and insula...
