In the prior art, when it needs to realize optical signal/power transmission, optical signal transmission lines and power transmission lines are both needed to be supported, as a result, construction operation can be troublesome, while, with the optical fiber composite overhead insulated cable adopted, the above problem can be solved. The optical fiber composite overhead insulated cable comprises a plurality of wire cables which are arranged side by side. The optical fiber composite overhead insulated cable is advantageous in that the wire cables are connected together through connecting ribs; the length of the connecting ribs are the same with that of the wire cables; cavities are formed in the connecting ribs along the length direction of the wire cables; optical fibers are arranged inside the cavities; and the optical fibers extend along the length direction of the connecting ribs.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of optical fiber composite overhead insulating cable.
Background technology
The Main Function of cable is the transmission for electric power, and the effect of optical fiber mainly is with the form of light signal to be transmitted.Existing cable and optical fiber is because their effects different, do not consider to allow them lay simultaneously arranging, and generally speaking, their layings between the two all have sequencing, when they are laid, all need to construct respectively.This is just so that construction operation comparatively bothers, and operating efficiency is lower.
Chinese invention patent application (application number: disclose a kind of fiber optic cables 95117789.3), it comprises the many optical fiber that are divided into each assembly, each assembly is coated with the supporting sheath, the outer fibers of itself and assembly is joined, in order to closely keep being included in the optical fiber in the described assembly, so that they mechanically connect mutually, a whole set of assembly can be placed in the outer jacket of being made by insulating material, wherein outer jacket can join with the lateral components of assembly cover, in order to form the fine and close member that is comprised of described assembly; Described cable is characterised in that, every optical fiber has the cut-off wavelength that is not more than 1,350nm, and close 1, on the wavelength of 550nm, have the mode field diameter that is in 7 μ m to the 9 μ m scopes, and wherein every optical fiber provides the basically sheath of sealing at its fiber cladding.
This fiber optic cables are take optical signal transmission as main, can not carry out electric power transfer, if transmission when will realize light signal and electric power then needs to go in addition the laying power cable again.Therefore, this fiber optic cables do not have the advantage of operation saving in construction.
Summary of the invention
For overcoming defects, the utility model technical issues that need to address are: a kind of optical fiber composite overhead insulating cable is provided, and this cable can be realized transferring of light signal and electric power simultaneously, so that constructing operation is convenient.
For solveing the technical problem, the technical solution of the utility model: a kind of optical fiber composite overhead insulating cable, comprise the some cables that are set up in parallel, it is characterized in that, link together by dowel between these cables, dowel and cable are isometric, and the length direction of cable along the line is formed with cavity in dowel, be provided with optical fiber in this cavity, optical fiber extends along the length direction of dowel.This cable generally is to be fixed on shaft tower or the wall body by gold utensil when installing, and easy for installation, insulation property are good, is transferred to simultaneously user terminal to realize light signal and electric power.
As preferably, described cable comprises conductor and is wrapped in the insulating barrier of conductor periphery, and described dowel and insulating barrier are that homogeneous material is one-body molded.The insulating barrier of dowel and cable is extruded simultaneously, becomes one, and this is so that the manufacturing speed of this cable is fast, and the bonding strength between each cable can be guaranteed.
As preferably, described cable is arranged to two row, and described optical fiber is arranged between the two alignment cables.Can effectively utilize the flexibility of cable itself to provide protection for optical fiber, be conducive to guarantee the fail safe of cable optical fiber in storage, transportation, installation process.
As preferably, described dowel is in the part evagination at fiber position place and formed parcel, and parcel is wrapped in the periphery of optical fiber.Parcel can provide good protective effect for optical fiber, and so that between the two alignment cables other parts of dowel do not need to be made very thick, the materials amount that is conducive to save dowel.
As preferably, described conductor comprises the some cylindrical cores that are set up in parallel, and seven cores form the single line bundles, and the intrafascicular peripheral core of the six roots of sensation of single line is arranged in the periphery of center core, and peripheral core is tangent to each other, and all tangent with the center core; Seven wire harness have consisted of described conductor, and the peripheral wire harness of the six roots of sensation in the conductor is arranged in the periphery of centred beam, and peripheral wire harness is tangent to each other, and all tangent with centred beam.Conductor is formed by described mode setting by columniform core, so that conductor has adapted to the requirement that optical fiber arranges, cable is flexible, and being conducive to provides protection for optical fiber.
The beneficial effects of the utility model are: optical fiber composite overhead insulating cable is a kind of inside that optical fiber is compounded in aerial insulated cable, the cable with electric power transfer and optical communication transmittability.Can realize power optical fiber to the family, utilize the aerial cable line that is routed to the rural electricity consumption terminal, take full advantage of electrical network " last kilometer " resource.This cable is integrated power network resources, realize " Joint construction and sharing " of network infrastructure, practice country " integration of three networks " strategy, the repeatedly construction that can solve many circuits such as electric wire, netting twine, telephone wire, cable television line, avoid overlapping construction impact order along the line and overlapping investment.This optical fiber composite overhead insulating cable is on the basis of using for reference twisting type bundled insulated conductors application experience, by the novel cable of architecture advances formation.Novel bundle assembled aerial cable is compared with the twisting type insulated conductor, can shorten 1.7-2.7 percentage point of wire electrical distance at the circuit that sets up equal length, can reduce power loss and the cost of cable self.Also have simultaneously production process few, wire rod has the advantages such as obvious architectural feature.
