Abstract
The utility model discloses a self-bearing-type overhead photoelectric composite cable which comprises a plurality of wire cores. Optical cables are arranged in gaps among the plurality of wire cores which comprise transmission wire cores and tensile wire cores. Because of adopting the structure, the utility model has the advantages that a plurality of strands of steel wires have the tensile capability, are suitable for large-span laying, and remedy the defects of an overhead insulation wire, the steel cores can be used as ground lines, the optical cables and the insulated wire cores are cabled to conveniently lay and maintain the optical cables, and the cables and the optical cables have respective functions, simultaneously transmit electric and communication signals without mutual interference, and have favorable transmission performance.
Description
Technical field
The utility model relates to power cable and communication cable technical field, and particularly a kind of self-bearing type is maked somebody a mere figurehead the photoelectricity composite cable.
Background technology
At present, aerial insulated wire has series of advantages, as dwindle the cable infall spacing and parallel distance, lay convenience, flexibility height, reduce occupation space, significantly reduce the frequency of power cut that causes because of line fault and electric shock accidents, the fail safe of raising electrical network and reliability etc.But aerial insulated wire in the mountain area or physical features when having the place of drop to lay cable tend to can't normally lay because cable self is overweight.Equally, the appearance of optical cable has advanced the development of communications industry greatly, and along with the arrival in 3G epoch, the application of optical cable has obtained unprecedented development, but traditional cable installation in pipe pattern complex operation of optical cable, safeguards that inconvenience, cost are high.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provides that a kind of suitable large span is laid, the built on stilts photoelectricity composite cable of self-bearing type of electric energy transmitting and communication signal simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of self-bearing type is maked somebody a mere figurehead the photoelectricity composite cable, comprises a plurality of cores, is provided with optical cable in the gap between described a plurality of cores, and described core comprises transmission core and tension core.
Described transmission core comprises conductor, is arranged on the insulating barrier of conductor periphery.
Described tension core comprises steel core, is arranged on the insulating barrier of steel core periphery.
Described steel core is the steel wire strand lay configuration.
The laying up pitch of described cable is greater than the minimum bending radius of described optical cable.
The utility model adopts said structure, has the following advantages: 1, steel wire strand has resistance to tension and is fit to large span and lays, and has remedied the deficiency of aerial insulated wire; 2, steel core can serve as the ground wire use; 3, optical cable and insulated wire cores stranding, the laying and safeguarding of convenient optical cable, and cable and optical cable Each performs its own functions, electric energy transmitting and communication signal simultaneously, both do not disturb mutually, transmission performance is good.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is a cross section structure schematic diagram of the present utility model;
In Fig. 1,1, optical cable; 2, transmission core; 3, tension core; 4, steel core.
Embodiment
A kind of as shown in Figure 1 self-bearing type is maked somebody a mere figurehead the photoelectricity composite cable, comprise a plurality of cores, be provided with optical cable 1 in the gap between a plurality of cores, optical cable 1 and the stranded stranding of a plurality of cores, the laying and safeguarding of convenient optical cable 1, and Each performs its own functions for cable and optical cable 1, while electric energy transmitting and communication signal, and both do not disturb mutually, transmission performance is good.
Core comprises transmission core 2 and tension core 3.Transmission core 2 comprises conductor, is arranged on the insulating barrier of conductor periphery, and this insulating barrier can adopt aerial insulated cable black cross-linkable polyethylene insulation material.Tension core 3 comprises steel core 4, is arranged on the insulating barrier of steel core 4 peripheries, and this insulating barrier can adopt aerial insulated cable black cross-linkable polyethylene insulation material.Steel core 4 is the steel wire strand lay configuration, and steel wire not only can be used as tensile elements, and can be used as ground wire usefulness, but transmission current such as short circuit current, induced current etc.
The drawing of the conductor of transmission core 2 is carried out on wire drawing machine, bright and clean, the no greasy dirt of surface of conductors, no marking, and resistance is up to state standards.With reference to process chart conductor is carried out strandedly, extrude insulating barrier then.Steel core 4 is that the multiply structure is stranded, can make twisting pitch smaller for increasing its flexibility, extrudes insulating barrier on extruder.Insulating barrier adopts the aerial insulated cable black cross-linkable polyethylene insulation material of JB/T10260-2001 regulation.The speed of the working temperature of plastic extruding machine various piece, the rotating speed of screw rod, traction is up to specification, with reference to the suitable mould of the size Selection of core, can not be eccentric during unwrapping wire, and each parts are wanted co-ordination.Surface of insulating layer is bright and clean, smooth, no flake etc.Stranding is carried out to built on stilts core, steel wire core and optical cable 1 in the back, and for keeping its performance, the laying up pitch of cable is greater than the minimum bending radius of optical cable 1.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection range of the present utility model.
