Abstract
The utility model discloses a two-core semicircular structural cable, comprising a sheath, wherein the sheath is internally provided with two semicircular conductors, and the bottom surfaces of both semicircular conductors are connected together to form a circular cable core. Compared with the prior art, the use amount of the sheath, a wrapping strip and a filling material is effectively reduced, the consumption material of the cable is saved and the manufacturing cost is reduced while the power transmission efficiency is guaranteed as two insulating wire cores are combined and connected to form one circular cable; in addition, as two ends of the bottom surfaces of two semicircular conductor cores are provided with round angles, the impact of electric field concentration on an insulating layer is effectively solved, the service life of the cable is prolonged and the safety of the cable is improved.
Description
Technical field:
The utility model relates to power cable, particularly a kind of two core semicircular structure cables.
Background technology:
Power cable is meant and is used for electric power conveying and electric power installation that it has a wide range of applications in electric power system, plant equipment, instrument and meter system.
Former two its structures of core circular configuration cable as shown in Figure 1, two round insulation cores place sheath 104, and the outside of two round conductors then is enclosed with insulating barrier 102, between insulating barrier 102 and sheath 104, one deck belting layer is arranged, part in the belting layer (removing insulated wire cores) is then all filled by filler 103, the protective cover material of this structural cable, band and inserts consumption are big, have increased the manufacturing cost of cable virtually.
Summary of the invention:
For this reason, the purpose of this utility model is to provide a kind of two core semicircular structure cables, to reduce the manufacturing cost of cable, the useful life and the fail safe that improve cable.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of two core semicircular structure cables comprise sheath (201), are provided with two semicircular conductors (202) in the described sheath (201), and the bottom surface of described two semicircular conductors (202) links together, and form a round cable core.
The outside of wherein said semicircular conductor (202) is enclosed with an insulating barrier (204), forms insulated wire cores.
The wherein said round cable core outside is enclosed with one deck band (203).
The two ends, bottom surface of wherein said semicircular conductor (202) are provided with fillet.
Compare with original technology, the utility model adopts two insulated wire cores to be connected into a round cable, when guaranteeing power transmission efficiency, has effectively reduced sheath, band and inserts, has saved the cable materials, has reduced manufacturing cost; In addition, be provided with fillet, thereby efficiently solve the concentrated impact of electric field, the useful life and the fail safe that have improved cable insulating barrier at the two ends, bottom surface of two semicircular conductor cores.
Description of drawings:
Fig. 1 is existing two core circular configuration construction of cable schematic diagrames.
Fig. 2 is the utility model two core semicircular structure construction of cable schematic diagrames.
Fig. 3 is the structural representation of the utility model semicircular conductor core.
Identifier declaration among the figure: sheath 201, semicircular conductor 202, band 203, insulating barrier 204, filler 205.
Embodiment:
For setting forth thought of the present utility model and purpose, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See also Fig. 2, shown in Figure 3, the utility model provides a kind of two core semicircular structure cables, include sheath 201 and two semicircular conductors 202 that are arranged in the sheath 201, the outside of semicircular conductor 202 is enclosed with an insulating barrier 204, form semicircle insulated wire cores, the bottom surface contact of these two semicircle insulated wire cores, form a round cable core, wherein said sheath 201 is pvc sheath or other sheath materials, semicircular conductor 202 is copper or aluminium core conductor, and these two ends, two semicircular conductor 202 bottom surfaces respectively are provided with a fillet.
Be enclosed with an insulating barrier 204 in the outside of semicircular conductor 202, the insulating barrier 204 here is polyvinyl chloride insulation layer or other insulation material layers, by this insulating barrier 204 that two semicircular conductors 202 of adjacent bottom surface contact are isolated, and at fillet place, two ends, two halves round insulation core bottom surface to having one to fill the space, correspondence is provided with filler in this filling space, by the fixed-site of this filler, move to prevent to produce with semicircle insulated wire cores.
Be enclosed with a band 203 in the outside of the formed cable core of two halves round insulation core, can realize above-mentioned filler is fixed by this band 203.
In the outside of band 203 then is pvc sheath or other sheath materials, by this sheath band 203 and semicircle insulated wire cores is implemented protection.
The utility model adopts two semicircular conductors to be connected and forms a complete round cable, and the two ends, bottom surface at two semicircular conductors are provided with fillet, thereby efficiently solve the concentrated impact of electric field, the useful life and the fail safe that have improved cable to insulating barrier.
Compare with original two core circular configuration cables, reduced 30%～40% with the semi-circular structural cable in cross section and the finished diameter of round structure cable, the amount of protective cover material and band has reduced 30～40% on year-on-year basis, the consumption of inserts has reduced 80%, save the cable materials, thereby reduced the manufacturing cost of cable.
More than a kind of two core semicircular structure cables described in the utility model are described in detail, used specific case herein principle of the present utility model and execution mode are set forth, the explanation of above example just is used for helping to understand core concept of the present utility model; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
