Abstract
The utility model relates to a carbon nano fiber cable core which comprises an insulating layer and a core layer. The core layer is composed of a carbon fiber composite material and a resin system. The insulating layer toroidally winds the outer layer of the core layer. According to the utility model, the above technical scheme is adopted; compared with an ordinary steel core cable, the weight is reduced by a quarter; the tensile strength of the cable core is improved; the ability of various wind, rainstorm and other harsh environment resistance of a carbon fiber cable is greatly improved; the service life is obviously prolonged; the demands of places with large overhead span are satisfied; the overhead relaxation degree is reduced; the height of a rack bar is reduced; and the erection cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of cable core, especially a kind of carbon nano-fiber cable core.
Background technology
Electric power is carried at a distance, usually adopts cable, and a kind of common overhead cable adopts steel reinforced aluminium conductor usually, and it is comprised of steel wire and two piths of conduction aluminium wire.The effect of steel wire is the unsettled load of bearing whole cable, and aluminium wire plays electric action.The advantage of steel wire is to have strong bearing capacity, but that shortcoming is self weight is large, and tensile strength is little, and the thermal coefficient of expansion of steel core is large.If considering electric wire has ice and snow or bears the high wind effect again, opposing external force ability, suspended scaffold with heavy cable there is very high requirement, require suspended scaffold not only strong, and rigidity will be got well, and the height of suspended scaffold is enough high, and this electric power is carried and brought great cost burden.Therefore be badly in need of that a kind of own wt is light, tensile strength is large, high temperature resistant, corrosion resistant cable, what development was very fast now is carbon fiber cable.Be unfavorable for secondary twisting and solidify but existing carbon fiber cable core is easily loose, fatigue performance is poor simultaneously, the somewhere defective easily occurs and causes the phenomenon of wire fracture.
The utility model content
For above-mentioned existing problems, the utility model provides a kind of carbon nano-fiber cable core, by the change of structure, can effectively solve loose problem, improves simultaneously fatigue performance.
In order to reach above purpose, the utility model is taked following technical scheme, a kind of carbon nano-fiber cable core, comprise insulating barrier and sandwich layer, described sandwich layer is made of carbon fibre composite and resin system, described insulating barrier hoop is wrapped in the sandwich layer skin, it is characterized in that: wherein, elastomer in the described composite material is its non-crosslinked form, and under 150 ℃, use the PULSED NMR technology, measure by the Hahn-echo method, the first spin-spin relaxation time of described composite material is the 100-3000 microsecond, and not having the second spin-spin relaxation time or the second spin-spin relaxation time is the 1000-10000 microsecond, and the mark of composition with second spin-spin relaxation time is less than 0.2.
The carbon fiber cable of being made by carbon fiber complex core, compare common steel core cable, not only own wt alleviates 1/4th, also improved the tensile strength of cable core, greatly improved the adverse circumstances abilities such as the anti-various strong wind of carbon fiber cable, heavy rain, useful life is obviously long, can also satisfy the built on stilts large place of span, built on stilts degree of speeding is reduced, can reduce the hack lever height, the larger reduction set up cost.

1, cable core 2, insulating barrier 3, sandwich layer 4, carbon fibre composite 5, resin system.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment one
As depicted in figs. 1 and 2, a kind of carbon nano-fiber cable core, comprise insulating barrier 2 and sandwich layer 3, described sandwich layer 3 is made of carbon fibre composite 4 and resin system 5, described insulating barrier hoop is wrapped in the sandwich layer skin, it is characterized in that: add after the multi-beam carbon-fiber impregnating resin system and be twisted thigh, the angle of twist scope of twisting is 1-10 °.Insulating barrier is generally glass fibre yarn or cloth.
Described carbon fibre composite comprises elastomer and the carbon fiber complex core that is dispersed in this elastomer, described carbon fiber complex core is the carbon fiber complex core that carbon nano-fiber silk, ceramic fibre silk and glass mat are made by thermosetting resin cured typing, and described carbon fiber wire is the filament of being made by polyacrylonitrile-based carbon fibre cellulose mixture carbon fiber; Wherein, elastomer in the described composite material is its non-crosslinked form, and under 150 ℃, use the PULSED NMR technology, measure by the Hahn-echo method, the first spin-spin relaxation time of described composite material is the 100-3000 microsecond, and not having the second spin-spin relaxation time or the second spin-spin relaxation time is the 1000-10000 microsecond, and the mark of composition with second spin-spin relaxation time is less than 0.2.
Embodiment two
With a kind of carbon nano-fiber cable core of embodiment one, its difference is: this carbon nano-fiber cable 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.
Claims (1)
1. carbon nano-fiber cable core, comprise insulating barrier and sandwich layer, described sandwich layer is made of carbon fibre composite and resin system, described insulating barrier hoop is wrapped in the sandwich layer skin, it is characterized in that: wherein, elastomer in the described composite material is its non-crosslinked form, and under 150 ℃, use the PULSED NMR technology, measure by the Hahn-echo method, the first spin-spin relaxation time of described composite material is the 100-3000 microsecond, and not having the second spin-spin relaxation time or the second spin-spin relaxation time is the 1000-10000 microsecond, and the mark of composition with second spin-spin relaxation time is less than 0.2.
