Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a processing method for power cables, which solves the problem that the existing hardening removal method requires production personnel to spend a lot of time on operation and monitoring, which increases the workload of production personnel and greatly reduces the production of cables. Efficiency, it is impossible to achieve fast and convenient de-hardening of the core conductor of the cable, and it is impossible to simplify the production process of the cable and reduce the production cost.

Embodiment 1

[0031] S1. Manufacture of cable core conductors: During the production of cable core conductors, it is necessary to select copper metal materials after removal of impurities as the core conductor base material, and then carry out the following processing procedures for production and manufacturing:

[0032] a1. Wire drawing treatment of copper metal materials: firstly, the selected copper metal materials are drawn through a wire drawing machine, and the single wire is thinned to the required diameter. After the copper metal materials are processed by the wire drawing machine, the metal materials are drawn into a fine copper wire with a diameter of 0.4mm;

[0033] a2. Copper wire twisting treatment: Twist and twist the multiple single wires drawn in step a1 together through a twisting machine, and use a tight hoop to hold and fix the twisted copper wires. The tight hoop is made of steel Made of plastic materials, the upper and lower hoops are connected and fixed by fastening sc...

Abstract

The invention discloses a processing method of a power cable. The processing method specifically comprises the following steps of (S1) manufacturing of a wire core conductor of a cable, namely (a1) wire drawing treatment of a copper metal material, (a2) twisting treatment of copper wires, (a3) hardening removal treatment of the wire core conductor and (a4) combination treatment of a wire core; (S2) manufacturing of an insulated wire core; (S3) manufacturing of a cable sheath; and (S4) quality control of the cable. The invention relates to the technical field of power cable processing. According to the processing method of the power cable, oven heating can be replaced through induction heating on the wire core conductor, the production staff do not need to spend a lot of time to operate andmonitor, the workload of the production staff is reduced, the production efficiency of the cable is greatly improved, the target of quickly and conveniently carrying out good hardening removal treatment on the wire core conductor of the cable is well achieved, and the targets of simplifying the production procedure of the cable and reducing the production cost are achieved, thereby greatly facilitating cable production work of the production staff.

Description

technical field [0001] The invention relates to the technical field of power cable processing, in particular to a power cable processing method. Background technique [0002] Cables are usually composed of several wires or groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outside is covered with a highly insulating covering. The cable has the characteristics of internal energization and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables and aluminum alloy cables, all of which are made of single or multiple strands Composed of wires and insulating layers, it is used to connect circuits and electrical appliances. Power cables are generally buried in the soil or laid indoors, in trenches and tunnels. The insulation distance between lines i...
