Description

Carbon fiber cable

Technical field

The utility model relates to cable, is specifically related to a kind of cable of interior carbon fiber-containing.

Background technology

Electric power is carried at a distance, adopts cable usually, and a kind of common overhead cable adopts steel reinforced aluminium conductor usually, and it is made up of steel wire and two piths of conduction aluminium wire.The effect of steel wire is a 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 big, and tensile strength is little, and the thermal coefficient of expansion of steel core is big.If considering electric wire again has ice and snow or bears the high wind effect, opposing external force ability, the suspended scaffold that has 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 big, high temperature resistant, corrosion resistant cable.

The utility model content

For solving above technical problem, the purpose of this utility model is, carbon fiber cable is provided.

The technical problem that the utility model solved can realize by the following technical solutions:

Carbon fiber cable comprises oversheath, metal screen layer, cable core, it is characterized in that, described cable core comprises carbon fiber complex core, aluminium conductor, the stranded cable core of making of described carbon fiber complex core and described aluminium conductor.

Described carbon fiber complex core is the carbon fiber complex core that carbon fiber wire, ceramic fibre silk are made by thermosetting resin cured typing.

Described carbon fiber wire is the filament of being made by polyacrylonitrile-based carbon fibre cellulose mixture carbon fiber, excellent properties such as that carbon fiber wire has is in light weight, corrosion-resistant, high strength, high-modulus, tensile strength are big.

Described ceramic fibre silk is the filament of being made by ceramic fibre, advantage such as that ceramic fibre has is in light weight, high temperature resistant, Heat stability is good, anti-mechanical oscillation.

Described carbon fiber complex core can be that carbon fiber wire mixes stranded bunchy with the ceramic fibre silk, also can be respectively with carbon fiber wire and ceramic fibre silk bunchy, be combined into rope again, the utility model especially adopts in the ceramic fibre silk and is mixed with carbon fiber wire, again compound ceramic fibre bundle is combined into rope, at last by thermosetting resin cured one-tenth with integral body.The carbon fiber cable of making 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, improved adverse circumstances abilities such as the anti-various strong wind of carbon fiber cable, heavy rain greatly, useful life is obviously long, can also satisfy the built on stilts big place of span, built on stilts degree of speeding is reduced, can reduce the hack lever height, the bigger reduction set up cost.

Described aluminium conductor is the heat-resisting aluminium alloy round conductor, and described aluminium conductor is laid in outside the described carbon fiber complex core, and both are twisted into cable core.

The composite material that described oversheath adopts rubber and polyvinyl chloride to constitute.Described composite material not only has high flexibility, also has characteristics such as corrosion-resistant and wear-resisting simultaneously.Described metal screen layer can be the metallic shield net of being made by metal wire knitted, and wire can be silver-coated copper wire.

Beneficial effect:, the utlity model has advantages such as own wt is light, tensile strength is big, high temperature resistant, corrosion-resistant owing to adopted technique scheme.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.

With reference to Fig. 1, carbon fiber cable comprises oversheath 1, metal screen layer 2, cable core 3, and cable core 3 comprises carbon fiber complex core 31, aluminium conductor 32, carbon fiber complex core 31 and the aluminium conductor 32 stranded cable cores 3 of making.Carbon fiber complex core 31 is carbon fiber complex cores that carbon fiber wire, ceramic fibre silk are made by thermosetting resin cured typing.

Carbon fiber wire is the filament of being made by polyacrylonitrile-based carbon fibre cellulose mixture carbon fiber, excellent properties such as that carbon fiber has is in light weight, corrosion-resistant, high strength, high-modulus, tensile strength are big.The ceramic fibre silk is the filament of being made by ceramic fibre, advantage such as that ceramic fibre has is in light weight, high temperature resistant, Heat stability is good, anti-mechanical oscillation.

Carbon fiber complex core 31 can be that carbon fiber wire mixes stranded bunchy with the ceramic fibre silk, also can be respectively with carbon fiber wire and ceramic fibre silk bunchy, be combined into rope again, the utility model especially adopts in the ceramic fibre silk and is mixed with carbon fiber wire, again compound ceramic fibre bundle is combined into rope, at last by thermosetting resin cured one-tenth with integral body.The carbon fiber cable of making 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, improved adverse circumstances abilities such as the anti-various strong wind of carbon fiber cable, heavy rain greatly, useful life is obviously long, can also satisfy the built on stilts big place of span, built on stilts degree of speeding is reduced, can reduce the hack lever height, the bigger reduction set up cost.

Aluminium conductor 32 is the heat-resisting aluminium alloy round conductor, and aluminium conductor 32 is laid in outside the carbon fiber complex core 31, and both are twisted into cable core 3.Aluminium conductor 32 lays the number of plies can be decided as required, it can be one deck, it also can be multilayer, with reference to Fig. 1, especially adopt two-layer, such cable core because of there being the gap between conductor, good bandability not only, also be easy to heat radiation, high temperature resistant, can obviously improve electrical conductor heating temp grade, thereby increase ampacity.
