Embodiment Construction

[0024] (1) The oxygen-free copper wire is used as the solid conductor 1, and the physical foamed polyethylene insulating material co-extruded with three layers of skin-foam-skin is used to extrude the insulating layer 2 on the oxygen-free copper wire to form an insulated wire core. The physical foaming insulation technology of skin-foam-skin three-layer co-extrusion is adopted, which is carried out on the Rosenthal series production line imported from Germany, and the material is selected from the physical foaming material imported from Dow Chemical. In the production process, adopt reasonable mold design and appropriate nitrogen injection pressure to ensure the thickness and concentricity of the inner and outer skins, the diameter of the insulated core and the foaming degree of the intermediate insulating layer in the process design, so that the insulation The single wire has electrical and mechanical properties suitable for the finished cable.

[0025] (2) Two insulated wire...

Abstract

The invention discloses an anti-torsion data power composite cable and a manufacturing method thereof. The composite cable comprises a cable core, an outer jacket, and is provided with a data line core and a power control line core; wherein, the data line core is formed by stranding of quad and positioned in the center of cable, the quad is provided with two insulated cores and drainage lines, and wounded and wrapped with a plastic-aluminum composite strip sub-shielding layer, the data line core is provided with a main shielding layer, the power control line core is formed in a manner that multi-assemble reinforced cores are mounted on the periphery of the data line core, the data line core and the cable core are provided with a composite cushion layer respectively. The invention has the advantages of simple and reasonable structure, advanced technique, high mechanical strength of products, low capacity and low attenuation. The invention is also characterized by strong anti electromagnetic interfere property, shock resistance, fine torsion bending resistance property, oil proofness, chemical solvent resistance, hard wearing, high / low temperature resistance, water erosion resistance, environmental leaching and loss resistance, ensuring stable property of cables in various severe environments so that cable property is reliable and safe.

Description

technical field [0001] The invention relates to a cable, in particular to the structure of a power cable for frequently moving construction machinery equipment, and belongs to the technical field of cables. Background technique [0002] In the power supply and measurement control lines of frequently moving engineering machinery and equipment, especially in machine tools and conveying lines with mechanical stress, in industries such as automated mechanical assembly lines, iron and steel metallurgical rolling plates, etc., with continuous and frequent reciprocating motion dragging, laying The various components of the cable are always in a state of dynamic winding movement. During this process, the cable is generally in a free state while being towed, and the conductor of the cable bears the main moving traction. During the movement, the bending radius of the cable is only a few times of its own outer diameter. After thousands of reciprocating movements, under high-speed and...
