Abstract
The invention discloses an optical fiber composite low-voltage cable, which comprises a cable core, wherein a packing layer is arranged at a clearance of the cable core; an inner protective sleeve, an armor layer and an outer protective layer are wrapped outside the cable core in sequence; the cable core is formed by the condition that a plurality of power cable cores and a plurality of optical cables are stranded; and each optical cable is formed by an optical fiber, a loose tube, an armor layer and a shielding layer, wherein the loose tube, the armor layer and the shielding layer are wrapped outside the optical fiber. With the adoption of the optical fiber composite low-voltage cable, the structure that a plurality of optical cables and a plurality of power cable core are combined are adopted, so that the construction workload is lowered, the construction period is shortened, and the phenomenon that the cable is easily damaged due to concentration of stress when the cable is subjected to an external action force is avoided, therefore, the stability and the safety in an optical fiber composite low-voltage cable running process are increased. The optical fiber composite low-voltage cable has the advantages of being excellent in mechanical performance, simple to lay and long in service life and the like, and electric energy transmission and signal transmission are not interfered mutually.
Description
Technical field
The invention belongs to power cable, optical communication field, be specifically related to a kind of optical fiber composite low-voltage cable.
Background technology
Along with national grid and south electric network strengthen construction to intelligent grid, except backbone network is built high pressure, superhigh pressure large capacity transmission circuit energetically, try hard to recommend power optical fiber to the family at user side.Power optical fiber refers to the family, connects in low pressure communication
Adopt optical fiber composite low-voltage cable that optical fiber is laid with lv power cable in the networking, thereby realize that intelligent electric meter to the family, cooperates passive optical network technique, the business such as the collection of carrying power information, intelligent power two-way interactive, the fusion of many nets.It is few that at present China cable producer can research and develop and produce the enterprise of optical fiber composite low-voltage cable, and all cable core all adopts many power and an optical cable to combine, although this spline structure is simple, because the power line core conductor adopts metal material, and the optical cable employing all is nonmetallic materials, but in the cable core manufacture process, power core and optical cable laying tension are inconsistent, thereby cause easily the optical fiber composite low-voltage cable profile of finished product to be serpentine, be not easy to cable installation in pipe, and in laying installation or use procedure, when optical fiber composite low-voltage cable is subject to external influence power, because optical fiber all concentrates in the optical cable, cause easily optical fiber simultaneously impaired, thereby cause whole optical fiber composite low-voltage cable to be scrapped.
Summary of the invention
The purpose of this invention is to provide that a kind of mechanical performance is high, delivery of electrical energy and the signal transmission does not interfere with each other, reliability is high, it is simple to lay, optical fiber composite low-voltage cable long service life.
A kind of optical fiber composite low-voltage cable of the present invention, comprise cable core, gap at cable core is provided with packed layer, cable core coats inner sheath, armour and outer jacket outward successively, described cable core is by some power cores and some stranded the forming of optical cable, and its optical cable is by optical fiber and be coated on successively optical fiber outer loose sleeve pipe, armour, screen.
Further improve, described power core is by conductor and be extruded in the outer insulating barrier of conductor and consist of.
Further improve, described optical cable radical and power core radical keep consistency, one by one corresponding evenly distribution during stranded arrangement.
Further improve, fill cable cream between described optical fiber and the loose sleeve pipe, optical fiber excess length is controlled between 4 ‰ to 6 ‰.
Beneficial effect of the present invention is:
The present invention coats one deck armour after optical fiber coats loose sleeve pipe, for optical cable has increased clad, thereby the mechanical performance of optical cable strengthens.The optical cable of power core same root number is corresponding one by one when stranding is stranded evenly to distribute, and has guaranteed the stressed uniformity of every optical cable, thereby has reached the stability of structure.And avoided each core of cable core to become the situation of " S " shape to occur because unbalance stress causes finished product, form that the combination that is easy to cable installation in pipe, optical cable and power core is easy to the residential quarter electric energy and signal equipment lays simultaneously, reduced the construction working amount, reduced the construction period, save project cost, reduced cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of optical fiber composite low-voltage cable of the present invention, comprise cable core, be provided with packed layer 10 in the gap of cable core, cable core coats inner sheath 7, armour 8 and outer jacket 9 outward successively, described cable core is by some power cores and some stranded the forming of optical cable, and its optical cable is by optical fiber 1 and be coated on successively optical fiber 1 loose sleeve pipe 2, armour 3, screen 4 outward.
Power core described above is by conductor 5 and be extruded in the outer insulating barriers 6 of conductor 5 and consist of; Described optical cable radical and power core radical keep consistency, one by one corresponding evenly distribution during stranded arrangement; Fill cable cream between described optical fiber 1 and the loose sleeve pipe 2, the remaining length of optical fiber 1 is controlled between 4 ‰ to 6 ‰.
The invention provides a kind of optical fiber composite low-voltage cable; the above only is preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention; can also make some improvement, these improvement also should be considered as protection scope of the present invention.
