Abstract
The utility model relates to the field of power transmission, and particularly discloses an overhead insulated cable. The overhead insulated cable is provided with a plurality of single-core overhead insulated cables, and each single-core overhead insulated cable comprises a conductive wire core, as well as a conductor shielding layer, an insulating layer, an insulating and shielding layer, a metal shielding layer and an outer sheath which are sequentially coated on the outer surface of the conductive wire core from the inside out. The overhead insulated cable is improved in the way that the plurality of single-core overhead insulated cables are stranded and cabled together; the overhead insulated cable further comprises wire cables and load-bearing steel strands; the load-bearing steel strands are placed in parallel in the length direction of the stranded and cabled single-core overhead insulated cables; and the wire cables are wound around and fastened outside both the load-bearing steel strands and the plurality of single-core overhead insulated cables, so that the load-bearing steel strands and the plurality of single-core overhead insulated cables are bound together. The overhead insulated cable provided by the utility model saves space, is safe and reliable, has large transmission capacity, and is convenient to mount and lay.
Description
Technical field
The utility model relates to the electric power transportation art, is specifically related to a kind of boundling self-bearing type aerial insulated cable.
Background technology
Along with continuing to increase of urban skyscraper density, also there is contradiction in building with greening.For underground space inadequate resource, there is the place that intersects in the transmission of electricity corridor with greening, adopts traditional built on stilts plain conductor, and it is big to take up room, and conductor wire core does not have insulating barrier, poor reliability, and oneself can not satisfy the city actual needs; And adopt single aerial insulated cable, and in order to alleviate the weight of cable, adopting the aluminium core conductor more, transmission capacity is smaller, must separate certain distance between the single insulated cable, and space hold is also more.In addition, in the city, adopt traditional built on stilts plain conductor also to have the safety problem of circuit.
The utility model content
The purpose of this utility model is the deficiency that overcomes existing product, provide a kind of saving space, safe and reliable, transmission capacity big, install and lay power transmission and transformation line aerial insulated cable easily.
For achieving the above object, the technical scheme of realization above-mentioned purpose is:
A kind of aerial insulated cable, have many single core overhead insulated cables, conductor shield, insulating barrier, insulation screen, metal screen layer and oversheath that described single core overhead insulated cable comprises conductor wire core and is coated on the conductor wire core outer surface from inside to outside successively; The described many stranded strandings of single core overhead insulated cable together; It also comprises steel wire rope and carrying steel strand wire, described carrying steel strand wire are along the parallel placement of the length direction of described many single core overhead insulated cables behind stranded stranding, described steel wire rope is around pricking outside carrying steel strand wire and many single core overhead insulated cables, will carry steel strand wire and many single core overhead insulated cables bundle.
In order to reach the purpose of protection, described carrying steel strand wire skin is extruded with one deck weather resistant sheath and described steel wire rope skin is extruded with one deck weather resistant sheath.
Described single core overhead insulated cable is three.
Described conductor wire core is the conductor of soft copper or hard copper, aluminium, aluminum alloy materials.
The beneficial effects of the utility model are: because cable also comprises steel wire rope and carrying steel strand wire, described steel wire rope is around pricking outside carrying steel strand wire and many single core overhead insulated cables, to bundle along parallel carrying steel strand wire and the many single core overhead insulated cables placed of the length direction behind the stranded stranding of many single core overhead insulated cables, play fixing and suspension effect, therefore, this Stability Analysis of Structures, safe and reliable to operation, the space is saved in practical application, lay conveniently, owing to increased the steel strand wire carrying, the conductor of cable can use the big copper core of transmission line capability (or hard copper core, the aluminium core, aluminium alloy core) large size conductor.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model structural section schematic diagram;
Fig. 2 is the vertical schematic diagram of the utility model.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
As shown in Figure 1, 2, a kind of aerial insulated cable, have three single core overhead insulated cables, conductor shield 2, insulating barrier 3, insulation screen 4, metal screen layer 5 and oversheath 6 that described single core overhead insulated cable comprises conductor wire core 1 and is coated on conductor wire core 1 outer surface from inside to outside successively, the described many stranded strandings of single core overhead insulated cable are together; Also comprise steel wire rope 8 and carrying steel strand wire 7; Described carrying steel strand wire 7 are along the parallel placement of the length direction of many single core overhead insulated cables behind stranded stranding; Described steel wire rope 8 will carry steel strand wire 7 and many single core overhead insulated cables and bundle around pricking outside carrying steel strand wire 7 and many single core overhead insulated cables.Described steel wire rope 8 is selected the magnaflux steel twisted wire for use.Described oversheath 6 is selected the weather resistant oversheath for use.
Described carrying steel strand wire 7 skins are extruded with one deck weather resistant sheath.Described steel wire rope 8 skins are extruded with one deck weather resistant sheath.Described weather-proof oversheath and weather resistant sheath are all selected the macromolecular material of light aging in anti-day for use, play a very good protection.
Described conductor wire core 1 is the conductor of soft copper or hard copper, aluminium, aluminum alloy materials.
Boundling self-bearing type aerial insulated cable described in the utility model can be selected the cross section of cable conduction core according to actual needs, also can require to select the core number of cable according to different transmissions of electricity.The suspended weights and the pulling force of whole cable satisfied in the cross section of wirerope fully, and the employing aviation will carry steel strand wire with steel wire rope and many single core overhead insulated cables bundle, and plays fixing and suspension effect.Single core overhead insulated cable, carrying steel strand wire and aviation all extrude the macromolecular material of the type of anti-marquis with the outside of steel wire rope, play a very good protection.The cable product compact conformation, easily manufactured, technical maturity, production cost is low.The installation of cable is laid also very convenient.Product effect in rated voltage 6kV-35kV cable line is good.Can on the online bar short crosspiece be installed when the utility model is installed, use the traction of wirerope and coaster to install, will carry wirerope and suspender at last and fix and get final product.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the execution mode of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
