Description

Technical Field

[0001] The utility model relates to the technical field of drag chain cables, in particular to a high-strength, tensile-resistant and oil-resistant flexible cable. Background Art

[0002] Traditional cables use Category 5 twisted conductors, ordinary filling, and PVC insulation sheath.

[0003] Since the drag chain cable needs to move back and forth repeatedly during use, rub against the ground and come into contact with oil, long-term operation will cause the sheath to wear and age, eventually leading to the breakage and cracking of the filling and sheath materials, greatly shortening the service life. Utility Model Content

[0004] The purpose of the utility model is to provide a high-strength, tensile-resistant and oil-resistant flexible cable to solve the problems in the prior art.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a high-strength tensile-resistant and oil-resistant flexible cable, comprising a central filling bar, a plurality of core wires evenly distributed on the outside of the central filling bar, and tensile-resistant filling bars arranged between adjacent core wires, the central filling bar, core wires and tensile-resistant filling bars are all wrapped by a non-woven fabric tape, and the outside of the non-woven fabric tape is covered with a nitrile polyvinyl chloride sheath; the core wire is composed of a conductor and a nitrile polyvinyl chloride insulation layer, and the outside of the conductor is covered with a nitrile polyvinyl chloride insulation layer.

[0006] Preferably, the conductor is a soft copper conductor.

[0007] Preferably, the central filling strip and the tensile filling strip are both made of polyester yarn.

[0008] Preferably, three core wires and three tensile filling strips are provided.

[0009] Compared with the existing technology, the beneficial effects of the utility model are: the conductor adopts soft copper conductor that exceeds the national standard Category 6, the single wire is thinner, and the bending effect is better; the insulation adopts modified polyvinyl chloride material, which is more wear-resistant and bending-resistant, and is not prone to cracks or breaks after repeated bending, and has good fatigue resistance; the polyester yarn is extruded and filled, which improves the tensile strength of the cable and is not easy to break; the sheath adopts modified polyvinyl chloride material, which is more wear-resistant, bending-resistant, and oil-resistant, and is not prone to cracks or breaks after repeated bending, and has good fatigue resistance, thereby extending the service life of the cable.
