Abstract
The utility model discloses an optical fiber composite low-voltage cable, including a cable core. A filling layer is arranged in gaps in the cable core. The cable core is externally provided with an inner sheath, an armor layer and an outer jacket in sequence. The cable core is formed by intertwisting a plurality of power cores and a plurality of optical cables, wherein each optical cable is composed of an optical fiber, a loose tube, an armor layer and a shielding layer, and the loose tube, the armor layer and the shielding layer are coated outside the optical fiber. According to the optical fiber composite low-voltage cable, the composite structure of the plurality of optical cables and the plurality of power cores is adopted, so that the construction workload is reduced, the construction period is shortened, phenomena that the stress is concentrated and a cable is easy to damage when the cable is subjected to an external force are prevented, thereby increasing stability and safety during the operational process of the optical fiber composite low-voltage cable. The optical fiber composite low-voltage cable is advantaged by being good in mechanical property, free of interference between electric energy transmission and signal transmission, high in reliability, simple to lay, long in use life, etc.
Description
Technical field
the utility model belongs to power cable, optical communication field, is specifically related to a kind of optical fiber composite low-voltage cable.
Background technology
Along with national grid and south electric network strengthen the construction to intelligent grid, except backbone network is built high pressure, superhigh pressure large capacity transmission circuit energetically, at user side, try hard to recommend power optical fiber to family.Power optical fiber refers to family, in low pressure communication, connects
In networking, adopt optical fiber composite low-voltage cable that optical fiber is laid with lv power cable, thereby realize that intelligent electric meter is to family, coordinate 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 is all nonmetallic materials, but in the cable core manufacture process, power core and optical cable laying tension are inconsistent, thereby easily cause 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 an optical cable, easily cause optical fiber simultaneously impaired, thereby cause whole optical fiber composite low-voltage cable to be scrapped.
The utility model content
The purpose of this utility model 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, lay simple, the optical fiber composite low-voltage cable of long service life.
A kind of optical fiber composite low-voltage cable described in the utility model, 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 form.
Further improve, described optical cable radical and power core radical keep consistency, during stranded arrangement one by one correspondence be uniformly distributed.
Further improve, fill cable cream between described optical fiber and loose sleeve pipe, optical fiber excess length is controlled between 4 ‰ to 6 ‰.
The beneficial effects of the utility model are:
The utility model coats one deck armour after optical fiber coats loose sleeve pipe, and for optical cable has increased clad, thereby the mechanical performance of optical cable strengthens.The optical cable of power core same root number when stranding is stranded one by one correspondence be uniformly distributed, guaranteed the stressed uniformity of every optical cable, thereby 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of optical fiber composite low-voltage cable described in the utility model, 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 outer loose sleeve pipe 2, armour 3, screen 4.
Power core described above is by conductor 5 and be extruded in the outer insulating barriers 6 of conductor 5 and form; Described optical cable radical and power core radical keep consistency, during stranded arrangement one by one correspondence be uniformly distributed; Fill cable cream between described optical fiber 1 and loose sleeve pipe 2, the remaining length of optical fiber 1 is controlled between 4 ‰ to 6 ‰.
The utility model provides a kind of optical fiber composite low-voltage cable; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
