The invention relates to a towline cable and a manufacturing process thereof. The towline cable structurally comprises a conductor, an insulator, a tensile core, an inner sheath and an outer sheath. The
radiation ethylene propylene rubber insulator is arranged on the periphery of the conductor, the low temperature resistant elastic body inner sheath is arranged on the periphery of the
radiation ethylene propylene rubber insulator, and the flexible
polyurethane outer sheath is arranged on the periphery of the inner sheath. The manufacturing process is that a tinned
copper wire is stranded by a wire cable stranding
machine to
server as the conductor, an extruder device is utilized to extrude the environment-friendly
radiation ethylene propylene rubber insulator on the outside of the conductor, the stranding
machine is utilized to strand high-strength tensile fibers, flexible
polyvinyl chloride (PVC) is extruded by the extruder device on the outer layer to serve as the tensile core, then a cabling
machine is utilized to strand an insulation wire core and the tensile core together, and the extruder device is utilized to extrude low temperature elastic body sheath materials to serve as the sheaths. The cable has the advantages of high
mechanical strength, flexibility, high abrasion resistance,
aging resistance,
cracking resistance, mould resistance,
moisture resistance and acid-base
corrosion resistance, is flexible under the low temperature condition and suitable for special environments such as weapons,
electronics, high-level civil use.
