Problems solved by technology

Most of the communication cables used in daily life have to be bent many times, and a little carelessness will cause the breakage of the inner line, which will affect the transmission of signals and the normal communication use of people. At present, high-strength cables have also been developed in the market. The high-strength performance of the cable is improved, but the physical and mechanical properties and transmission performance of the cable are affected by the addition of various inorganic materials

Abstract

The invention discloses a preparation method for a high-strength cable. The method includes the following steps that: 1) nano semimetal bismuth is bunched so as to be adopted as conductor cores with the core diameter ranging from 60 to 80 nm, each of the conductor cores is coated with an insulated high-strength cable material, so that high-strength insulated wire cores are formed; 2) 3 to 5 wire cores which have been treated in the step (1) are wound around a PV-filled liner core, one-time cabling and stranding are performed, so that a composite wire core can be obtained, a plurality of composite wire cores are arranged side by side, and corresponding force-bearing components are arranged, three-layer co-extrusion cross-linking is performed, two ends of a cross-linked cable are connected with a power source, so that a closed loop can be formed, and the cable is energized for a period of time; and 3) copper tape shielding, cabling armoring and outer sheath sleeving are performed on thecable treated in the step 2). The high-strength cable prepared by the preparation method has moderate softness; after the cable is used repeatedly, transmission speed is not affected; and the aging speed of the cable can be effectively slowed down. The preparation method of the present invention is particularly suitable for communication cables.

Description

technical field [0001] The invention relates to the field of cable preparation, in particular to a method for preparing high-strength cables. Background technique [0002] With the rapid development of economy, cables are widely used in communication, electric power and other fields. Most of the communication cables used in daily life have to be bent many times, and a little carelessness will cause the breakage of the inner line, which will affect the transmission of signals and the normal communication use of people. At present, high-strength cables have also been developed in the market. The high-strength performance of the cable is improved, but the physical and mechanical properties and transmission performance of the cable are affected by the addition of various inorganic materials. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for preparing a high-strength cable, which has moderate softness, does not...
