Special tensile dragging control cable and method for manufacturing same

Abstract

The invention discloses a special tensile dragging control cable. An insulating wire core consists of a plurality of multi-stranded zinc-coated soft steel wires, a tin-coated oxygen-free copper wire and an insulating extruded layer; a plurality of insulating wire cores are stranded into a cable core; a filling layer which consists of hemp ropes is filled in a clearance of the cable core; the cable core is wound with a tear-resistant polypropylene belt in an overlapping mode and extruded with a tensile wear-resistant polyurethane elastic outer sheath; the outermost layer of the cable is a braided zinc-coated steel wire outer sheath layer; each insulating wire core consists of the plurality of multi-stranded zinc-coated soft steel wires which serve as reinforcing cores and the tin-coated oxygen-free copper wire which serves as a copper conductor; and the insulating extruded layer is made of ethylene-propylene-diene monomer compound rubber. The special tensile dragging control cable has the characteristics of high tensile strength, high flexibility, high tear resistance, oil resistance, aging resistance, external environment weather resistance and the like, has excellent functions ofhigh bending winding capacity, dragging resistance, environment friendliness and the like, and is applicable to equipment such as a winding drum, a port machine and an excavator; and the service lifeof the dragging cable is greatly prolonged.

Description

Technical field: [0001] The invention relates to a special pull-resistant and dragging control cable and a manufacturing method thereof. Background technique: [0002] In China, the cables used in reels, port machinery, mining machines and other equipment and high-bending winding and towing places mainly use ordinary rubber-sheathed flexible cables and ordinary towing cables, and the conductors adopt ordinary bundled wire and twisted structures. , or improve the insulation and sheath characteristics of the cable, but during the operation of the cable, due to uneven force, excessive tension or high bending, high winding, etc., ordinary rubber-sheathed cables and ordinary dragging cables are in operation It is very easy to be damaged by external force. Broken core of the conductor is a common fault. The service life of the cable is generally about 3 months, which brings great inconvenience to the work, especially affects the improvement of production efficiency, and is not con...

[0002] In China, the cables used in reels, port machinery, mining machines and other equipment and high-bending winding and towing places mainly use ordinary rubber-sheathed flexible cables and ordinary towing cables, and the conductors adopt ordinary bundled wire and twisted structures. , or improve the insulation and sheath characteristics of the cable, but during the operation of the cable, due to uneven force, excessive tension or high bending, high winding, etc., ordinary rubber-sheathed cables and ordinary dragging cables are in operation It is very easy to be damaged by external force. Broken core of the conductor is a common fault. The service life of the cable is generally about 3 months, which brings great inconvenience to the work, especially affects the improvement of production efficiency, and is not conducive to industrial expansion.
