Abstract
The invention relates to an external optical composite low voltage cable, which comprises two cable cores, an insulating layer is wrapped out of each of the cable cores, a metal shielding layer is arranged outside the insulating layer of each of the cable cores, a cable protecting sleeve layer is wrapped out of the metal shielding layer, and optical fibers are arranged in the cable protecting sleeve layer. The external optical composite low voltage cable has the advantages that power transmission and optical communication transmission can be performed simultaneously, cooling effect is good, and cost is reduced.
Description
Technical field
The present invention relates to belong to field of cables, be specifically related to a kind of Optical Fiber Composite cable.
Background technology
Optical fiber is fibre-optic writing a Chinese character in simplified form, and is a kind of total reflection principle and the light conduction instrument reached of light in the fiber that glass or plastics are processed that utilize.Optical fiber is invented by the preceding principal Gao Kun of Hong Kong Chinese University.Fine optical fiber is encapsulated in the plastic sheath, makes that it can be crooked and be unlikely to fracture.Optical fiber communication at a high speed, reliable and stable, antijamming capability is strong, has become inundant development trend.
Lv power cable is meant each or a plurality of conductor outer wrap layer of annular insulating barrier, and the electric wire in conductor and the shared same axle center of insulating barrier, whole then cable is encased by the sheath of polyvinyl chloride or other materials, carries out the conduction instrument of electric energy transmitting.
Along with country carries forward vigorously " integration of three networks " strategy work; 2010, national grid was announced incision " integration of three networks " simultaneously on the basis of stepping up the intelligent grid construction; Start power optical fiber pilot project construction, " integration of three networks " strategy implementation of service country to the family.For adapting to the special demands of Urban House sub-district; Technology such as the intelligent computer network of solution residential quarters, equipment automatization; Through all kinds of conducting cable; Organically connect each subsystem of residential quarters, have functions such as electric power, data, video, network control, for office, study, life, amusement provide service.Original power cable only possesses the effect of transmission of electric energy; And the maximum characteristics of Optical Fiber Composite low-voltage cable are the functions that merged optical fiber communication and electric power transfer; Light harvesting fibre and power transmission and distribution cable are avoided the secondary wiring, can effectively reduce expenses such as construction, networking.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome deficiency of the prior art, provide a kind of and can carry out electric power transfer and optical communication transmission simultaneously, good heat dissipation effect, the compound low-voltage intelligent cable of novel external optical fiber of saving cost.
Technical scheme: in order to solve the problems of the technologies described above; The compound low-voltage cable of external optical fiber of the present invention; It comprises two cores, is wrapped with insulating barrier at every core, outside the insulating barrier of said every core, is provided with metal screen layer; Be provided with the cable cover(ing) layer in said metal screen layer outerwrap, in said cable cover(ing) layer, be provided with optical fiber.
Said optical fiber is made up of fibre core and fiber jacket.
Said core is a copper conductor.
Said optical fiber can be arranged on any position in the said cable cover(ing) layer.
The umbilicate figure of eight is justified at the two that is shaped as of said cable cover(ing) layer.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: the present invention is located at optical fiber in the cable cover(ing) layer, has improved radiating effect greatly, simultaneously normal use is not had other any harmful effects.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1, the compound low-voltage cable of a kind of external optical fiber of the present invention belongs to field of cables, and it comprises two cores 1; Be wrapped with insulating barrier 2 at every core 1; Outside the insulating barrier 2 of said every core 1, be provided with metal screen layer 3, it is to prevent to produce induction between two cores 1 that said metal screen layer 3 is set, in order to avoid influence is used; Be provided with cable cover(ing) layer 4 in said metal screen layer 3 outerwrap, in said cable cover(ing) layer 4, be provided with optical fiber 5; Said optical fiber 5 is made up of fibre core and fiber jacket; Said core 1 is a copper conductor; Said optical fiber 5 can be arranged on any position in the said cable cover(ing) layer 4, and said optical fiber 5 laterally arranges with said core 1, and the umbilicate figure of eight is justified at the two that is shaped as of said cable cover(ing) layer 4.Overall structure of the present invention is simple, is installed in optical fiber in the cable cover(ing) layer, can effectively improve radiating effect, most importantly can also carry out simultaneously electric power transfer and optical communication the transmission, solved problems such as secondary wiring, better controlled cost.
The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
