Abstract

The invention discloses a method for improving the flexibility of an optical cable, which comprises the following steps: adding synthetic mechanical oil to the water tank of a water tank drawing machine, and heating the water tank; after pickling, phosphating, galvanizing and blanking Enter the stage of cold drawing; pass the cold drawn wire through the synthetic mechanical oil in the water tank drawing machine, pass the optical cable raw materials through the holes from large to small in turn, gradually make the diameter smaller, and then temper; The silk is the core, and the thin wire is wrapped outside the thick wire to make thick strands and thin strands respectively, and the thick strands and thin strands are oiled and coated; the rope is combined, and a thick strand is used as the rope core, and 4~ 6 thin strands are paired with 1 thick strand, and the thin strands are combined outside the thick strands. The strength of the cable core pulled out by this invention is reduced by 3-5%, the cable core is more flexible and bendable, and the number of torsion experiments is increased by 10-15%. The thick and thin wires are combined, and the thick and thin strands are combined to make the cable more flexible and fatigue-resistant.

Description

technical field [0001] The invention relates to the technical field of methods for improving the flexibility of optical cables, in particular to a method for improving the flexibility of optical cables. Background technique [0002] Optical cables need to withstand alternating loads during use, and their performance is mainly determined by the mechanical properties of the cable core, the surface state of the cable core and the structure of the optical cable. The cable core material includes carbon steel or alloy steel, which is formed by cold drawing or cold rolling. The cross section of the cable core is round or shaped. The shaped cross section cable core is mainly used for the production of sealed optical cables and has high tensile strength. And toughness, and appropriate surface treatment of the cable core to meet the needs of different environmental conditions. [0003] Traditional optical cables are cooled and drawn with saponified liquid, and the cable core has high...
