Problems solved by technology

The coaxial cable is composed of inner conductor layer, insulating layer, outer conductor layer and sheath layer. The inner conductor layer and outer conductor layer are usually small in section and have poor self-supporting performance, especially when the cable is used under the working condition of not being buried in the ground. , due to poor load-bearing performance, the weight of the cable itself will cause the cable conductor to break, and it is also easy to damage the small cable conductor during construction
In the prior art, the support frame is used to support the cable, and the coaxial cable is protected by adding a support frame, which has a certain effect, but increases the laying cost and time, and the cable itself has poor load-bearing performance, and it is inevitable during the construction process. The problem of damage to the core of the cable caused by careless operation
[0003] Chinese patent "ZL201520373236.X" discloses a coaxial cable, the main content of which is to add a strengthening layer outside the outer conductor, which improves the overall tensile performance of the cable to a certain extent. In this working condition, the stress concentration point of the cable is at the center point of the cable, the center point is not protected, and the tensile performance of the inner conductor has not been solved; due to the addition of one or more layers of structure in the cable, The processing procedure is increased, the production efficiency is reduced, and the weight of the cable is increased. On the one hand, it affects the installation, and on the other hand, it increases the pressure of the inner conductor during the load-bearing process.

Abstract

The invention discloses a self-bearing high-power coaxial composite cable, which comprises an inner conductor center bearing core, a buffer layer, a tubular inner conductor, an insulating layer, an outer conductor and an outer sheath from the inside to the outside, wherein the outer conductor is formed by winding bearing metal wires and outer conductor conductive single wires, which are of a same number, alternately and then combining the winding bearing metal wires and outer conductor conductive single wires with at least one control insulated wire core; a single-wire ridge is also arranged on the outer sheath; the height of the single-wire ridge is not smaller than 0.5mm; and the width is not smaller than 1mm. The cable has a good self-bearing property; the center bearing core is arranged in a center layer of the inner conductor of the cable; force bearing points of the inner conductor are concentrated on the center bearing core; an annealed copper wire of the inner conductor is protected in the take-up, unreeling and winding processes of the cable; and the cable is not prone to breakage.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a self-supporting high-power coaxial composite cable. Background technique [0002] Today's world has entered the information age, and information has become a strategic resource for economic development and a unique factor of production. A modern information transmission system and a complete information service system established by combining long-distance communication networks, computers, video and other multimedia terminals, It has become an important symbol of the economic development of a country or region. Coaxial cable is an important variety in information transmission. It is mainly used as an antenna feeder for radio transmitting or receiving equipment and as an internal connection or interconnection line for various communications and electronic equipment. The coaxial cable is composed of inner conductor layer, insulating layer, outer conductor layer and sheath layer....
