Abstract
The present invention relates to a multi-core intertwisted type carbon-fibre composite cable core comprising an insulating layer and a core layer, wherein the core layer is composed by carbon fibers and a resin system, and the insulating layer circumferentially winds the external layer of the large core layer and is characterized in that a plurality of bundles of carbon fibers are dipped into the resin system and intertwisted into a strand, wherein the plurality of bundles of carbon fibers are intertwisted at a twist angle of from 1 DEG to 10 DEG. The adoption of the technical scheme of the invention brings about the advantages that: (1) the intertwisted carbon fibers are winded by glass fibers so that the intertwisted fibers are not easily unwound, thereby being helpful for the second twisting and solidification of the fibers; (2) the antifatigue performance of the cable core made by using the multi-core intertwisting technology is better than that of a single cable core having a same cross section as the multi-core cable core, thereby effectively avoiding the phenomenon that a defect occurs somewhere in the single core structure to result in fracture of a wire; and (3) the cable core having a multi-core structure has a small moment of inertia and good flexibility, thereby being able to reduce the diameter of a reel and being convenient for rolling, package and carrying.
Description
Technical field
The present invention relates to a kind of cable core, the stranded type carbon fiber composite material cable of especially a kind of multicore core.
Background technology
The used lead of transmission line mainly is steel reinforced aluminium conductor (ACSR) and Related product thereof all the time.This plain conductor itself has some shortcomings, and for example from great, unsuitable large span is built on stilts; Environmental corrosion, intermetallic corrosion are difficult to avoid; Big etc. to the metal demand.Along with the development of power industry, also more and more higher to the requirement of transmission pressure, the nineties in 20th century, Japanese scholar's research replaces steel core with carbon fiber core, has developed a kind of advanced composite material (ACM) synthesising wire, i.e. carbon fiber core aluminium stranded conductor (ACFR).This novel conductive wire is compared with conventional ACSR lead, have in light weight, coefficient of linear expansion is little, the radian characteristic is good, and do not need advantages such as special facility and method in the construction, we can say that the advanced composite material (ACM) synthesising wire is a kind of used for transmission line lead of novel concept, is a revolution of aerial high voltage power transmission lead.But existing carbon fiber electrically cable core is easily loose to be unfavorable for secondary twisting and to solidify, and fatigue performance is poor simultaneously, the somewhere defective easily takes place and causes the phenomenon of wire fracture.
Summary of the invention
At above-mentioned existing problems, the invention provides the stranded type carbon fiber composite material cable of a kind of multicore core, by the change of structure, can effectively solve loose problem, improve fatigue performance simultaneously.
In order to reach above purpose, the present invention takes following technical scheme, the stranded type carbon fiber composite material cable of a kind of multicore core, comprise insulating barrier and sandwich layer, described sandwich layer is made of carbon fiber and resin system, described insulating barrier hoop is wrapped in the sandwich layer skin, it is characterized in that: twist into thigh after the multi-beam carbon-fiber impregnating resin system, the angle of twist scope of twisting is 1-10 °.
Owing to the present invention has taked above technical scheme, have the following advantages: the one, thus carbon fiber twisting back winding glass fibre makes the fiber of twisted be difficult for loose help secondary twisting and curing; The 2nd, adopt the multicore twisting process to make the cable core fatigue performance good, and can effectively avoid single cored structure that the somewhere defective takes place and cause the phenomenon of wire fracture with cross section unit cable core; The 3rd, the cable core the moment of inertia of multicore structure is less, and pliability is good, can reduce reel diameter, is convenient to rolling, packing and transportation.The invention cable core is made cable and is applied to high-voltage fence construction and transformation, can significantly improve the electrical network transmission capacity, improves safe operation of electric network, reduces the power grid construction gross investment.

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Embodiment one
As depicted in figs. 1 and 2, the stranded type carbon fiber composite material cable of a kind of multicore core, comprise insulating barrier 2 and sandwich layer 3, described sandwich layer 3 is made of carbon fiber 4 and resin system 5, described insulating barrier hoop is wrapped in the sandwich layer skin, it is characterized in that: twist into thigh after the multi-beam carbon-fiber impregnating resin system, the angle of twist scope of twisting is 1-10 °.Insulating barrier is generally glass yarn or cloth.
Embodiment two
With the stranded type carbon fiber composite material cable of a kind of multicore core of embodiment one, its difference is: the stranded type carbon fiber composite material cable of this multicore core is by 1 stranded composition of several strands of cables core, and direction of lay is opposite with the sub-thread twist direction or identical.
In addition to the implementation, the present invention can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of requirement of the present invention.
Claims (2)
1. cable core, comprise insulating barrier and sandwich layer, described sandwich layer is made of carbon fiber and resin system, and described insulating barrier hoop is wrapped in the sandwich layer skin, it is characterized in that: twist into thigh after the multi-beam carbon-fiber impregnating resin system, the angle of twist scope of twisting is 1-10 °.
2. a kind of cable core according to claim 1 is characterized in that: the stranded type carbon fiber composite material cable of this multicore core is by several bursts of stranded compositions, and direction of lay is opposite with the sub-thread twist direction or identical.
