Abstract
The utility model discloses a carbon fiber composite material bearing type signal transmitting cable, and is characterized in that conductor cores (1) are comprised; insulting layers (2) are coated outside the conductor cores (1) to form cable cores; the plurality of the cable cores and a carbon fiber composite core are all located inside a metal shielding layer (4); a belting layer (5) is arranged outside the metal shielding layer (4); and an outer low-smoke and halogen-free protective layer (6) is arranged outside the belting layer (5). The utility model solves the bearing material problem of the conventional bearing cable, the carbon fiber composite material, which is polymer based composite and nonmagnetic material, is adopted as a bearing body, so the signal transmission can not be obstructed and affected. The volume light density of the carbon fiber composite material is one quarter of that of a steel wire, and the strength of the carbon fiber composite material is two times stronger than that of the steel wire, and the temperature resistance is good (-80 to 300 DEG C), so that the carbon fiber composite material has the advantages of high strength, light weight, small sag and so on.
Description
Technical field
The utility model relates to a kind of power equipment, specifically a kind of construction of cable.
Background technology
Along with the swift and violent develop rapidly of China's economic, the acceleration transformation of the electrified network in town and country, electric wire enterprise is also meeting and is adapting to this challenge.The electric wire manufacturing industry supports as the high speed information highway of the national economic development; Along with improving constantly of information-based level of industry; Demand to electric wire is increasing, and is also increasingly high to the performance and the specification requirement of cable simultaneously, so there is powerful development potentiality in cable industry.Built on stilts requirement had both had security reliability as the circuit of rural power grids, urban network restructuring, also require simultaneously attractive in appearance take up room little.
Traditional carrying cable is that cable is carried in conduct after utilizing steel strand wire to extrude plastic insulation; Link together through the cable snap close with required communication cable signal cable then; Construction cost is high like this, and trouble is installed, and also might dangle and breaks accident because of snap close or installation question cause taking place cable.
A kind of carrying cable that cable and lifting-line are combined was arranged before, and this structural cable manufacturing cost is high, complex process, and because the magnetic material of steel wire causes the cable transmission signal influential.
Summary of the invention
The purpose of the utility model is exactly the deficiency to above-mentioned prior art, provides a kind of cost low, and the signal transmission is not disturbed and influence, and intensity is high, the carbon fibre composite bearing-type signal-transmitting cable that sag in light weight is little.
The technical scheme that the utility model adopts is following:
A kind of carbon fibre composite bearing-type signal-transmitting cable; It is characterized in that it includes conductor cores; Conductor cores is coated with insulating barrier, forms cable core, and said many cables core are positioned at metal screen layer with carbon fiber complex core; Be provided with belting layer in the metal screen layer outside, the belting layer outside is provided with the low smoke and zero halogen outer jacket.
Said carbon fiber complex core is positioned at a side of many cable floors, is filled with the non-hygroscopic packing material in the space between carbon fiber complex core and the said cable core.
The beneficial effect of the utility model has:
Solved the problem of materials that traditional carrying cable uses supporting body, adopted carbon fibre composite to do supporting body, material is nonmagnetic substance originally as polymer composite, and the signal transmission is not disturbed and influence.Carbon fibre composite is because the light density of volume is 1/4 of steel wire, and advantage such as intensity is 2 times of steel wire, and heatproof degree good (80～300 ℃) therefore has the intensity height, and is in light weight, and sag is little.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further:
As shown in Figure 1, the utility model is coated with insulating barrier 2 in conductor cores 1, forms cable core.Many cables core are positioned at metal screen layer 4 with carbon fiber complex core 3, are provided with belting layer 5 in metal screen layer 4 outsides, and belting layer 5 outsides are provided with low smoke and zero halogen outer jacket 6.
The utility model is pressed the required weight of cable and is selected suitable carbon fiber complex core 3 diameters, and counts diameter according to cable core, confirms structure, and its principle is the side that carbon fiber complex core 3 is positioned at many cable floors, therewith stranding.For guaranteeing the cable rounding, can in the space between carbon fiber complex core 3 and the said cable core, suitably fill the non-hygroscopic packing material, Overmolded band is extruded sheath and is formed, and uses more environmental protection.
Effect analysis: tradition carries cable and carbon fibre composite carries the contrast of cable section performance index like following table
| Performance requirement | Tradition is carried cable | Carbon fibre composite carries cable |
| Materials used | Steel strand wire | Carbon fibre composite |
| Electromagnetic interference | (need independent moulding or add screen) arranged | Do not have |
| The supporting body density of material | 7.8 | ≯2.0 |
| Mechanical strength MPa | 1240~1410 | 2480~2820 |
| Heat resistance | Temperature raises and raises | No change |
| Ground sag performance | ? | Than the reduction of conventional carriers more than 2 times |
| Construction maintenance | Need the secondary stringing, need to safeguard | Once accomplish Maintenance free |
Other undeclared part that the utility model relates to is identical with prior art.
