Abstract
Disclosed is a parallel bunched cable, mainly solving the problem of a trouble that conventional parallel bunched cables have to be bound and stringed in the stringing process. The parallel bunched cable comprises core wires (1) and insulating layers (2), wherein the core wires (1) are externally and tightly coated with the insulating layers (2) to form single-phase cables. The parallel bunched cable is characterized in that the three or four single-phase cables are formed into a parallel bunch and arranged like a shape of a triangle or a quadrangle; the outer walls of the insulating layers (2) of the adjacent single-phase cables are sequentially connected through connecting ribs (3); and the cross section of the parallel bunch is in a completely closed state. According to the utility model, the parallel bunched cable needs no binding in the stringing process; the stringing of the parallel bunched cable is time and labor saving; and the stringing efficiency of the parallel bunched cable is high.
Description
Technical field
The utility model relates to a kind of insulated aerial cable, is specifically related to a kind of parallel conductor cable.
Background technology
At present, insulated aerial cable has insulation property and certain resistance to corrosion, can effectively avoid phase fault and ground fault, is widely used in power distribution network.In the electric power course of conveying, the standard of China adopts the mode of movement of three-phase four-wire system, namely adopts triple line to carry during high-pressure delivery, adopts four lines to carry behind transformer pressure-reducing, both can use three-phase, also can use single-phase electricity.In order to make insulated aerial cable be convenient to set up, make simultaneously the suffered tension equalizer of each phase line, parallel bundling insulation aerial cable has appearred.Existing parallel cluster aerial cable mainly is comprised of heart yearn, insulating barrier and dowel, heart yearn is three or four, heart yearn outer cladding insulating barrier, wherein link to each other with other two or three cables successively by dowel as the basis take a cable, this parallel cluster aerial cable needs to bundle in use, to form positive square or triangle, bother during stringing.
The utility model content
Need when overcoming existing parallel cluster aerial cable stringing to bundle, the stringing trouble deficiency, the utility model provides a kind of parallel conductor cable, this cable need not bundle when stringing, stringing saves time, string efficiency is high.
The technical solution of the utility model is: this parallel conductor cable, comprise heart yearn and insulating barrier, the outer closely coated insulation layer of heart yearn forms single-phase cable, single-phase cable is three or four and is combined into parallel cluster, three or four single-phase cables are equilateral triangle or square is arranged, link to each other successively by dowel between the insulating barrier outer wall of adjacent single-phase cable, the cross section of parallel cluster is complete closure state.
Described dowel is positioned at the middle part of insulating barrier.
Described dowel is positioned at the outside and tangent with the insulating barrier face of cylinder of insulating barrier.
Described dowel and insulating barrier are integrated.
The beneficial effects of the utility model are: owing to take such scheme, three or four single-phase cables are connected, and are the parallel cluster of closure state, in use, need not bundle, and stringing is convenient, and stringing saves time, and string efficiency is high.If need to be with the terminals of parallel cluster separately when wiring, only need with one in electrician's hilt dowel or all cut open and get final product.
Description of drawings
Accompanying drawing 1 is that single-phase cable is three structural representation in the utility model.
Accompanying drawing 2 is that single-phase cable is four structural representation in the utility model.
Accompanying drawing 3 is that single-phase cable is the structural representation of another execution mode of three.
Accompanying drawing 4 is that single-phase cable is the structural representation of another execution mode of four.
1-heart yearn among the figure, 2-insulating barrier, 3-dowel.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2, Fig. 3, shown in Figure 4, this parallel conductor cable comprises heart yearn 1 and insulating barrier 2, heart yearn 1 outer tight coated insulation layer 2 forms single-phase cable, single-phase cable is three or four and is combined into parallel cluster, three or four single-phase cables are equilateral triangle or square is arranged, link to each other successively by dowel 3 between insulating barrier 2 outer walls of adjacent single-phase cable, the cross section of parallel cluster is complete closure state.Owing to take technique scheme, three or four single-phase cables are connected, and are the parallel cluster of closure state, in use, need not bundle, and stringing is convenient, and stringing saves time, and string efficiency is high.If need to be with the terminals of parallel cluster separately when wiring, only need with one in electrician's hilt dowel 3 or all cut open and get final product.
Described dowel 3 is positioned at the middle part of insulating barrier 2.The distance of dowel 3 is short, saves material.
Described dowel 3 is positioned at the outside and tangent with insulating barrier 2 faces of cylinder of insulating barrier 2.Be convenient to processing, outward appearance is neat.
Described dowel 3 is integrated with insulating barrier 2.Dowel 3 adopts same material with insulating barrier 2, and parallel cluster is stressed evenly, is easy to processing.
Claims (4)
1. parallel conductor cable, comprise heart yearn (1) and insulating barrier (2), the outer closely coated insulation layer (2) of heart yearn (1) forms single-phase cable, it is characterized in that: single-phase cable is three or four and is combined into parallel cluster, three or four single-phase cables are equilateral triangle or square is arranged, link to each other successively by dowel (3) between the insulating barrier of adjacent single-phase cable (2) outer wall, the cross section of parallel cluster is complete closure state.
