Abstract
The invention discloses an optical fiber composite low-voltage power cable suitable for a voltage level of being equal to or less than 0.6/1kv. The power cable comprises a cable core, wherein the cable core is formed by four control wire cores which are arranged together in parallel, and then are filled with a foam factice water-blocking layer; a shielding layer, an inner sheath, a steel band armored layer, an elastic buffer layer and an outer sheath are arranged on the cable core in sequence; a group of optical fibers are symmetrically arranged in the inner sheath; and an air hole is formed in the inner surface of the outer sheath. According to the cable, due to the combination of the corresponding optical unit and the control wire cores, the electric energy equipment and communication equipment can be laid for a residential area at the same time, so that the construction workload is reduced, the construction period is shortened, the construction cost is saved, and the cost is lowered.
Description
Technical field
The invention belongs to power cable, optical communication field, be specifically related to a kind of optical fiber composite low-voltage power cable, be primarily adapted for use in 0.6/1kv and following electric pressure.
Background technology
China's intelligent grid is just at the early-stage in incoming end light fibrillation.The expert of national grid and south electric network points out, intelligent grid necessarily needs to utilize optical fiber cable, and extraordinary electric power optical cable and optoelectronic composite cable brute force support.China utilizes built maximum, the advanced electric power special optic fibre communication network reliably in the world of the special optical cables such as OPGW, OPPC, ADSS, and its application level is in international advanced.Generally in " backbone network is strong, Access Network is weak ", the situation of " high (voltage) end is strong, and low side is weak ", distribution/user accesses that communication gap in side is relatively big, communication network basis is the weakest.The low bottleneck being press-fitted, having become by the communication system of power grids technology restriction intelligent grid application.Owing to traditional F TTH scheme is at the high cost of user side transformation and laying, almost nil in the optical fiber rate of user side access electrical network at present, China's intelligent grid is at the early-stage in the light fibrillation of incoming end.Therefore to realize power optical fiber to be badly in need of a kind of composite cable with low-voltage power and optic communication duplicate transmissions ability to family new technique.
In response to the needs that China's intelligent grid is built, realize power optical fiber to family new technique, overcome at present in Building Construction, it is common to a plurality of circuits such as the electric wire that exists, netting twine, telephone wire, cable television line are repeatedly constructed the significant wastage of cable resource that phenomenon causes and conduit resource.Along with national grid and south electric network strengthen the construction to intelligent grid, except backbone network builds high pressure, supertension large capacity transmission circuit energetically, try hard to recommend power optical fiber to family at user side.Power optical fiber refers to family, low voltage communication Access Network adopt optical fiber composite low-voltage cable laid with lv power cable by optical fiber, thus realizing intelligent electric meter to family, coordinate the business such as passive optical network technique, carrying power information collection, intelligent power two-way interactive, multi-internet integration.The enterprise that cable producer of current China could research and develop and produce optical fiber composite low-voltage cable is few, and all cable core all adopts many power and an optical cable to combine, although this spline structure is simple, because power wire core conductor adopts metal material, and optical cable employing is all nonmetallic materials, therefore optical fiber composite low-voltage cable light unit in manufacture and use procedure is subject to external forces damage, causes that optical fiber composite low-voltage cable cannot be properly functioning, even scraps.
Summary of the invention
It is an object of the invention to provide a kind of mechanical performance is high, reliability is high, safety is high 0.6/1kv and following optical fiber composite low-voltage power cable.
A kind of optical fiber composite low-voltage power cable of the present invention, including cable core, described cable core refills foam ointment water blocking layer and forms after being placed in together side by side by four control conductor；Screen layer, inner sheath, steel-tape armouring layer, elastic cord breaker and oversheath it is sequentially provided with outside cable core；One group of optical fiber it is arranged with in described inner sheath；Described oversheath inner surface is provided with a pore.
Improving further, described control conductor is made up of aluminium alloy conductor, the insulating barrier being extruded in outside aluminium alloy conductor and the beam tube that is squeezed in outside insulating barrier.
Improving further, described elastic cord breaker includes pad outside the interior pad of flexibility and flexibility, pads and be provided with some air bags between pad outside flexibility in described flexibility.
The beneficial effects of the present invention is:
1, the combination of light unit of the present invention and control conductor is prone to residential quarter electric energy and signal equipment lays simultaneously, reduces construction workload, decreases the construction period, saved construction costs, reduces cost.
2, the elastic cord breaker of the present invention can effectively cushion from extraneous pressure, and well protection core and optical fiber are without damage.
3, optical fiber is arranged in inner sheath by the present invention, it is possible to it is independent for making control conductor and optical fiber, it is not necessary to is extruded in cable core, is independent of each other, does not interfere with each other so that the performance of cable is more stable, better.
4, being provided with pore in oversheath of the present invention, being primarily to cable can better dispel the heat, and reduces cable temperature, also reduces cable high irregular working because of temperature simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of the elastic cord breaker of the present invention.
Detailed description of the invention
As it is shown in figure 1, a kind of 0.6/1kv of the present invention and following optical fiber composite low-voltage power cable, including cable core, described cable core refills foam ointment water blocking layer 4 and forms after being placed in together side by side by four control conductor；Described control conductor is made up of aluminium alloy conductor 1, the insulating barrier 2 being extruded in outside aluminium alloy conductor 1 and the beam tube 3 that is squeezed in outside insulating barrier 2；Then, outside cable core, it is sequentially provided with screen layer 5, inner sheath 6, steel-tape armouring layer 7, elastic cord breaker 8 and oversheath 9；So that control conductor and optical fiber are independent of each other, do not interfere with each other, in inner sheath, it is arranged with one group of optical fiber 10 so that the performance of cable is more stable, better；In order to cable can better dispel the heat, reduce cable temperature, also reduce cable high irregular working because of temperature, so jacket inner surface is additionally provided with a pore 11 outside simultaneously.
As in figure 2 it is shown, described elastic cord breaker 8 includes padding 82 outside pad 81 and flexibility in flexibility, padding and be provided with some air bags 83 between pad outside flexibility, effectively cushioned from extraneous pressure in described flexibility, good protection core and optical fiber are without damage.
The above be only the present invention be preferable to carry out method, it is noted that for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to make some improvement, these improvement also should be regarded as protection scope of the present invention.
