Abstract
The utility model discloses a composite optical fiber low-voltage cable, belongs to the field of a composite optical fiber low-voltage cable, and is mainly applied to the fields of communication, electric power, information, network or the like. The utility model aims to provide the cable which enables electric power signals, telecommunication signals and other signals to be transmitted simultaneously. The technical scheme of the utility model is that conductors(1) coated with insulating layers (2) form insulating cores (3); the plurality of insulating cores (3), an optical communication transmission unit (5) and a radial water-blocking filling (4) are intertwined to form cable cores (6); and an inner lining layer (7) and an outer sheath (8) are arranged outside the cable cores in order. With the above technical scheme, the cable of the utility model enables telecommunication network signals, broadcast and television network signals, internet signals and other signals to be transmitted while enabling electric power to be transmitted.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of Optical Fiber Composite low-voltage cable, and it is mainly used in fields such as communication, electric power, information, network.
Background technology
Existing 0.6/1kV lv power cable only has single electric power transfer function.As: Chinese patent CN101236801A discloses a kind of fire-resistant low-voltage power.It is signal such as transmitting telecommunication transferring electric power the time again.
Optical cable has the function of signals such as good transmitting telecommunication.As: Chinese patent CN201075139Y discloses a kind of dry type layer strand optical cable.Its only can transmitting telecommunication etc. signal, transferring electric power simultaneously.
" many nets merge " is the target of national intelligent grid development, requires electric transmission network, telecommunications network, broadcasting and television network, the Internet etc. are effectively merged.For this reason, the power cable that needs a kind of transferring electric power simultaneously and signal.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of Optical Fiber Composite low-voltage cable of the signal of transferring electric power and telecommunications etc. simultaneously is provided.
For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: a kind of Optical Fiber Composite low-voltage cable, the conductor of its coated insulation layer constitutes insulated wire cores, many eradication edge cores, at least one optical communication transmission unit and the stranded together formation cable core of filling that radially blocks water, the outer wrapped inner covering of cable core, inner covering extrudes oversheath outward.Optical communication transmission unit wherein adopts one, two, three or more.
Further, thoroughly do away with the edge core is four eradication edge cores more.
Further, the optical communication transmission unit is the cable line of built-in fiber, and this cable line adopts dry type layer tangle structure, dry type central beam tubular construction, ointment filled type layer tangle structure or ointment filled type central beam tubular construction.
Further, block water radially that to fill be the PP rope that adopts polypropylene material.
After adopting technique scheme, the utlity model has following beneficial effect:
(1) many eradication edge cores, at least one optical communication transmission unit and the stranded together formation cable core of filling that radially blocks water make cable signals such as energy transmitting telecommunication net, broadcasting and television network, the Internet in transferring electric power, and net of realization made up more.Satisfy intelligent grid informationization, automation, interactive demand.
(2) adopt the edge cores that thoroughly do away with more, improve the electric power transfer effect, and convenient processing.
(3) the optical communication transmission unit is the cable line of built-in fiber, and it selects dry type layer the tangle any structure of structure or ointment filled type central beam tubular construction of structure, dry type central beam tubular construction, ointment filled type layer that tangles.Improve the laser propagation effect of signal on the one hand, under the situation that cable jacket partly damages, adapt to different operating positions on the other hand, can partly keep the signal transmission.
(4) the PP rope that adopts polypropylene material improves block-water effect as the filling that radially blocks water.
Description of drawings

Embodiment
As shown in Figure 1, a kind of Optical Fiber Composite low-voltage cable, the conductor 1 of its coated insulation layer 2 constitutes insulated wire cores 3, four thoroughly do away with edge core 3, an optical communication transmission unit 5 and radially block water and fill 4 stranded together formation cable cores 6, cable core 6 outer wrapped inner coverings 7, the inner covering 7 outer oversheaths 8 that evenly closely extrude.
Wherein:
A, radially block water and fill the 4 preferred PP ropes that adopt polypropylene materials;
B, optical communication transmission unit 5 are cable lines of built-in fiber, and cable line is dry type layer tangle any structure in structure or the ointment filled type central beam tubular construction of structure, dry type central beam tubular construction, ointment filled type layer that tangles.
Certainly, optical communication transmission unit 5 also can adopt two, three, four or more.Four thoroughly do away with edge core 3, many optical communication transmission units 5 and the filling 4 stranded together formation cable cores 6 that radially block water, cable core 6 outer wrapped inner coverings 7, the inner covering 7 outer oversheaths 8 that evenly closely extrude.Adopt many optical communication transmission units 5 can improve the signal transmittability.
The Optical Fiber Composite low-voltage cable of employing said structure is signal such as transferring electric power and telecommunications simultaneously.The PP rope of polypropylene material wherein improves the block-water performance of Optical Fiber Composite low-voltage cable; Optional dry type layer the tangle any cable line of structure or ointment filled type central beam tubular construction of structure, dry type central beam tubular construction, ointment filled type layer that tangles, enlarge the range of choice of cable line in the Optical Fiber Composite low-voltage cable, adapt to the demand of different operating positions.
The utility model is not limited to the foregoing description, and the technical scheme that all employings are equal to or the equivalence replacement forms all belongs to the claimed scope of the utility model.
