Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
The utility model discloses it is shown in fig. 1 that tow chain cable 1 is used in the removal, including a plurality of insulation core 2, wrap around a plurality of insulation core 2's non-woven fabrics 4, cladding at the outside restrictive coating 5 of non-woven fabrics 4 and fill cotton rope 3 between a plurality of insulation core 2 and non-woven fabrics 4, a plurality of insulation core 2 transposition stranding, insulation core 2 is including being used for electrically conductive conductor 21 and cladding in conductor 21's insulating layer 22. The scheme adopts the structure and the materials, improves the severe environment resistance and the bending resistance of the cable, prolongs the service life and the reliability of the cable, and reduces the maintenance frequency and the maintenance cost.
The cross-sectional shape of the cable in this embodiment is circular. Wherein the conductor 21 is made of oxygen-free copper, and is made into 0.08mm copper wire by refining by upward drawing method, wire drawing, etc., then several copper wires are combined into a strand, and several strands are twisted into the required conductor 21, such as conductor with nominal section of 0.2mm2The conductor 21 consists of 40 copper wires of 0.08mm, and during manufacturing, 5 single copper wires of 0.08mm are twisted into strands in the right direction and then 8 strands are twisted into strands in the left direction, wherein the required nominal section is 0.2mm2The conductor 21 of (a). The conductor is formed by processing a 0.08mm copper wire made of oxygen-free copper through wire bundling and compound stranding, wherein the elongation of the copper wire is not less than 25%, so that the tensile capacity and the bending resistance of the conductor 21 are ensured.
In this embodiment, a layer of high-temperature and low-temperature resistant polyvinyl chloride is extruded outside the conductor 21 to serve as the insulating layer 22, and the polyvinyl chloride is a soft elastomer, has the characteristics of stability, difficulty in corrosion by acid and alkali, and high heat resistance, and is suitable for severe environments. Several such insulated wire cores 2 are then stranded into a cable.
