Abstract
The utility model relates to a photoelectric composite cable, which comprises a power cable sheath, a plurality of power cables and a plurality of optical fiber cables, wherein the power cables and the optical fiber cables are arranged in the power cable sheath; each optical fiber cable comprises a bellows and a plurality of bundles of optical fibers arranged in the bellows; an optical fiber jacket is covered outside each bundle of the optical fibers; and a smooth elastic layer is coated outside the bellows. Each power cable comprises a cable conductor and a cable insulation layer wrapped outside the cable conductor. For the photoelectric composite cable, the optical fibers originally placed in a concentrated way are placed bundle by bundle in the stainless steel bellows with the surfaces coated with the smooth elastic layers, so that the normal operation of the photoelectric composite cable cannot be affected when a few optical fibers have faults, for the optical fibers have allowance; in addition, as the surface of each stainless steel bellows is coated with the smooth elastic layer, the stainless steel bellows can protect the optical fibers and cannot damage the cable insulation layers, so that the reliable performance of the photoelectric composite cable can be guaranteed.
Description
Technical field
The utility model relates to optical fibre communication cable, relates in particular to a kind of optoelectronic composite cable.
Background technology
In intelligent grid, " power distribution network operation information and power consumer information acquisition system " is an important link.Yet power telecom network has only been realized the optical fiber communication connected network communication to 110,000 volts of above high voltage substation and part 35kV transformer stations at present.The following power transformation (switch) of 35kV is stood, and especially the data communications collection of 400V low-voltage power user side belongs to the blind area substantially.This obviously can not satisfy intelligent grid " power distribution network operation information and power consumer information acquisition system " requirements on Construction.
Owing to 400V low voltage electric network broad covered area, enter huge numbers of families, by combining of 400V lv power cable and optical fiber, can also realize " Fiber to the home, many net fusions ".Therefore, " 400V Optical Fiber Composite cable " is the base components that " low-voltage network operation information and power consumer client information acquisition system " builds.
Yet traditional 400V lv power cable exists shortcomings such as " little flexible, the sheath armouring protection of cable are simple, the cable load is big, the space in the middle of the easy unofficial biography of conductor heat, heterogeneous electric wire is little, the cable copper core in the cable course of processing is big to the stranded pressure of optical cable, the traction force in the cable laying construction big ".Simultaneously, the mechanical strength of traditional fiber very a little less than, optical fiber is damaged easily, because the optical fiber in the existing optical cable all is to concentrate to be provided with, therefore, in case optical fiber damages, will influence the normal operation of optical cable, and traditional fiber is afraid of crooked, and excessive microbending loss will influence the effect of optical fiber communication.Therefore, optical fiber can be contained in one at present has in the metal matter conduit of high strength and small curvature radius.But this metal catheter may destroy insulating performance of cable, thereby dielectric strength is lowered, and the high-termal conductivity of metal also will influence the loss of communications index of optical fiber.
In view of the foregoing as can be known, press for a kind of Optical Fiber Composite cable that overcomes the problems referred to above of research and development at present, to satisfy the needs that " low-voltage network operation information and power consumer client information acquisition system " builds.
The utility model content
In order to solve the problem that above-mentioned prior art exists, the utility model aims to provide a kind of novel optoelectronic composite cable, and to guarantee its dependable performance, the needs that " low-voltage network operation information and power consumer client information acquisition system " builds are satisfied in normal operation.
A kind of optoelectronic composite cable described in the utility model, it comprises a power cable sheath, is arranged on some power cables and some optical cables in this power cable sheath, described optical cable comprises a bellows and is arranged on the interior some bundle optical fiber of this bellows, the outer coated optical fiber jacket of described every bundle optical fiber, the outer coating of described bellows one smooth elastic layer.
In above-mentioned optoelectronic composite cable, described power cable comprises cable conductor and is wrapped in the outer cable insulation of this cable conductor.
In above-mentioned optoelectronic composite cable, described some power cables and some optical cables are uniformly at intervals in described power cable sheath.
In above-mentioned optoelectronic composite cable, described optical fiber jacket is a nylon material.
In above-mentioned optoelectronic composite cable, described bellows is a stainless steel.
Owing to adopted above-mentioned technical solution, the utility model will be by concentrating the fiber beam splitting of placing to be placed in the stainless bellows of the smooth elastic layer of surface-coated originally, make the utility model after a small amount of optical fiber breaks down, because of optical fiber has surplus, and can not have influence on its normal operation; In addition, because stainless bellows surface scribbles smooth elastic layer, therefore in the course of processing, in protection optical fiber, be difficult for making this bellows damage cable insulation, thereby can guarantee the dependable performance of optoelectronic composite cable.
Description of drawings
Fig. 1 is the structural representation of a kind of optoelectronic composite cable of the utility model;
Fig. 2 is the structural representation of optical cable in a kind of optoelectronic composite cable of the utility model.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
See also Fig. 1, Fig. 2, the utility model, promptly a kind of optoelectronic composite cable, it comprises a power cable sheath 1, the some power cables in power cable sheath 1 and some optical cables 3 uniformly at intervals, wherein,
Power cable comprises cable conductor 21 and the cable insulation 22 that is wrapped in outside this cable conductor 21;
Optical cable 3 comprises the bellows 31 and the some bundle optical fiber 32 that are arranged in this bellows 31 of a stainless steel, the optical fiber jacket 33 of every bundle optical fiber 32 outer coated nylon materials, bellows 31 outer coating one smooth elastic layers 34, the material of this smooth elastic layer 34 is the LSOH anti-flaming elastomeric material.
The utility model has changed in the conventional cable optical fiber and has concentrated the mode that is provided with, and fiber beam splitting is arranged on 33 li of optical fiber jackets, therefore, even a small amount of optical fiber breaks down, also can be because of optical fiber have surplus, and can not influence the normal operation of optoelectronic composite cable; The utility model is also at the smooth elastic layer 34 of bellows 31 surface applied that wraps up optical fiber 32, thereby it is little to have overcome conventional metals pipe radius of curvature, the shortcoming of destructible power cable insulation performance has effectively been guaranteed the dielectric strength of power cable to have improved its reliability.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection range of the present utility model.
