Abstract
The utility model discloses a power line for a photoelectric composite cable, and the power line belongs to the field of cable, in particular belongs to a photoelectric composite cable provided with power lines. The power line for the photoelectric composite cable comprises a conductor wire core and an insulating layer, wherein the conductor wire core is a copper core, and the insulating layer is coated outside the conductor wire core. The power line for the photoelectric composite cable integrates optical fibers and power transmission copper wires, solves the problems in broadband access, power supply for equipment and signal transmission, and has the advantages of simplifying product structure, saving cost, and safe and reliable performances; in addition, the cable further has the advantages of simple forming process, easiness for laying, and excellent economical efficiency.
Description
Technical field
The utility model relates to a kind of optoelectronic composite cable power line, and specifically to belong to photoelectricity compound a kind of for power line, is applicable to the power demands of communication cable.
Background technology
Along with pushing forward comprehensively of " integration of three networks ", drive accelerating development of optical cable industry, brought more opportunities and challenges also for the development of optoelectronic composite cable.For adapting to the power demands of communication cable, for making communication and electric power transfer, often need respectively laying-out, this not only brings difficulty to construction, has also increased construction cost and material cost.And the diameter of optical cable is less, and tensile strength is low, fractures easily, simply power cable and optical cable are merged, although can reach the effect that improves cable intensity, because the impact of electric field, so that the transmission of signal is extremely unstable.Optoelectronic composite cable of the present utility model is applicable to make transmission line in the broadband access network system with power line, is a kind of novel access way, and its light harvesting fibre, transmission of electricity copper cash can solve the problem of broadband access, equipment electricity consumption, signal transmission in one.
Summary of the invention
The utility model provides a kind of optoelectronic composite cable power line, and this cable has technique and simple in structure, and safe and reliable advantage; In addition, this cable also has the insulation resistance height, and the characteristic pliability of the little and good cold flexibility of dielectric loss, resistance to wear, environmental stress crack resistance, processability is easy to lay, and low production cost, economical and practical characteristics.
For realizing above-mentioned technical purpose, the technical solution of the utility model is as follows:
A kind of optoelectronic composite cable power line comprises conductor thread core, insulating barrier, it is characterized in that: described conductor thread core is single or stranded copper core, and described insulating barrier is coated on the conductor thread core outside.
The cross section of conductor thread core described in the utility model is circular.
Insulating barrier described in the utility model is high density polyethylene (HDPE).
The utility model is the power unit of optoelectronic composite cable.The utility model 2-4 root is filled in the optoelectronic composite cable.
Specification described in the utility model, the performance index such as 20 ℃ of insulation resistances of conductor, insulated wire cores external diameter are as follows:
Annotate: 20 ℃ of conductor resistance values are no more than 2% of setting.
Because the utility model has adopted technique scheme, therefore, has following advantages:
1), the product external diameter is little, lightweight, it is little to take up room, its reason is: if do not adopt optoelectronic composite cable, adopt an optical cable to add the problem that at least one wire could solve, can replace with a composite rope at this, thereby the product external diameter is little, and is lightweight, and it is little to take up room;
2), client's purchase cost is low, operating expenses is low, the networking expense is low, because power line is placed in the photoelectric compound cable, has so just saved the restrictive coating of power line, has so just reduced product cost; This composite cable convenient construction and networking have also reduced its expense in addition;
3), have superior bending property and good anti-side pressure performance, easy construction; Because the polyethylene insulation electric wire has superior bending property and good anti-side pressure performance, so can satisfy the properties of optical fiber cable requirement;
4), save cost, optical fiber as the usefulness of reserving to the family, has been avoided the secondary wiring; Because this cable has carried out compound to optical cable and electric wire; When construction, just optical cable, disposable the laying of electric wire can be put in place like this;
5), solve equipment electrical problem in the fiber optic network construction and in the situation of avoiding repeating to connect up, solved satisfactorily power line during fiber optic network is built.
