Abstract
The utility model discloses a photoelectric composite power cable for an intelligent power grid, and the power cable comprises insulating cable cores, an optical unit, and a steel pipe unit. The optical unit is located inside the steel pipe unit. The periphery of the steel pipe unit is provided with four insulating cable cores which contact with each other and are distributed in the square shape. The steel pipe unit is located at the gap between the four insulating cable cores. The exterior of the four insulating cable cores is sequentially provided with a cladding layer, an inner sheath layer, an armor layer, and an outer sheath layer from the inside to the outside. The optical unit comprises an optical fiber unit, and a non-woven fabric layer outside the optical fiber unit. Each insulating cable core comprises a conductor cable core and an insulating layer outside the conductor cable core. According to the utility model, the power cable integrates an optical fiber and power transmission and distribution as a body, can effectively prevent the optical fiber unit from being extruded to cause a phenomenon of signal transmission attenuation, and is stronger in shock resistance and resistance to lateral pressure. Compared with a conventional power optical fiber, the power cable can save a lot of metal, pipelines, plastics, and other resources, and effectively reduces the cost of production.
Description
Technical field:
The utility model relates to a kind of cable, particularly relates to a kind of used for intelligent electric network photoelectricity composite power 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, 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.The develop rapidly of intelligent grid has all proposed new requirement to traditional optical cable and electric power transfer, and photoelectric compound cable is as intelligence
Staple product in can power grid construction, light harvesting fiber communication and electric power transfer be in one, meets intelligent grid informationization, automation, interactive demand, has stronger advantage and application more widely, will provide safe and reliable guarantee for intelligent grid construction.
Existing photoelectric compound cable is to consist of oversheath, the insulated wire cores twisting together and the fiber unit that are located in oversheath.This photoelectric compound cable fiber unit in manufacture or use procedure is easily subject to bending and extruding, causes the signal attenuation of optical fiber to exceed standard value, affects user and uses.
Utility model content:
Technical problem to be solved in the utility model is: a kind of used for intelligent electric network photoelectricity composite power cable that can effectively avoid fiber unit to be squeezed making signal attenuation is provided.
The utility model is that the technical scheme that technical solution problem is taked is:
A kind of used for intelligent electric network photoelectricity composite power cable, comprise insulated wire cores, light unit and steel pipe unit, it is inner that described smooth unit is positioned at steel pipe unit, in steel pipe unit surrounding, be provided with four insulated wire cores, described four insulated wire cores are in contact with one another and are square profile, the gap location of described steel pipe unit between four insulated wire cores; Outside in described four insulated wire cores is disposed with lapping layer, inner restrictive coating, armour and external sheath layer from the inside to the outside.
Described smooth unit comprises the nonwoven layer of fiber unit and fiber unit outside; Described four insulated wire cores include the insulating barrier of conductor thread core and conductor thread core outside.
Between described steel pipe unit and four insulated wire cores, be provided with filler.
Positive beneficial effect of the present utility model is as follows:
1, fiber unit of the present utility model is positioned at inside, steel pipe unit, the gap location of steel pipe unit between four insulated wire cores, therefore can avoid fiber unit to be squeezed and cause the generation of signal transmission attenuation phenomenon, have stronger shock resistance and resistance to side pressure performance, adaptive capacity to environment is strong.
2, the utility model light harvesting fibre and electric power transmission & distribution, are avoided secondary wiring, can effectively reduce the expenses such as construction, networking.Relatively traditional power optical fiber, can save the resources such as a large amount of metals, pipeline, plastics, effectively reduces production costs.
3, the utility model is simple in structure, easily manufactured, can effectively reduce every cost of community user, has good practical value.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to Fig. 1, a kind of used for intelligent electric network photoelectricity composite power cable, comprise insulated wire cores, light unit and steel pipe unit 3, light unit is positioned at 3 inside, steel pipe unit, in steel pipe unit 3 surroundings, be provided with four insulated wire cores, four insulated wire cores are in contact with one another and are square profile, the gap location of steel pipe unit 3 between four insulated wire cores; In the outside of four insulated wire cores, be disposed with from the inside to the outside lapping layer 7, inner restrictive coating 8, armour 9 and external sheath layer 10.Light unit comprises that 4, four insulated wire cores of nonwoven layer of fiber unit 5 and fiber unit outside include the insulating barrier 1 of conductor thread core 2 and conductor thread core outside, are provided with filler 6 between steel pipe unit 3 and four insulated wire cores.
It is inner that fiber unit of the present utility model is positioned at steel pipe unit, the gap location of steel pipe unit between four insulated wire cores, therefore can avoid fiber unit to be squeezed and cause the generation of signal transmission attenuation phenomenon, have stronger shock resistance and resistance to side pressure performance, adaptive capacity to environment is strong; And the utility model light harvesting fibre and electric power transmission & distribution are, avoid secondary wiring, can effectively reduce the expenses such as construction, networking.Relatively traditional power optical fiber, can save the resources such as a large amount of metals, pipeline, plastics, effectively reduces production costs.
