Abstract
The utility model relates to an aerial cable, in particular to suit for a convertible bundle assembled aerial cable with the agility of the stride requirement, aims to overcome the defect that the present aerial cable ca not set a plurality of cables a time in stride. A conductor(5) and a conductor insulation(6) of the cable constitute a single insulated wire core, a plurality of wire cores extrude the cabling, the middle of the conductor of the single insulated wire core takes a single steel wire(1) and a steel strand(3), the outer layer takes an adpressed aluminum conductor(2), the adpressed aluminum conductor(2) is made by a plurality of aluminum wire adpressed by the single layer or multilayer. The utility model has advantages of the load-bearing structure can be set in stride, low cost and safety and theft protection, more suitable for the improvement of the country power network.
Description
Technical field
The utility model relates to a kind of aerial cable, and especially a kind of large span that is applicable to requires collapsible flexibly bundle assembled aerial cable.
Background technology
The aerial cable of former standard GB 12527 regulations mainly is that single core insulation, conductor adopt aluminium, aluminium alloy, copper product, and polyvinyl chloride, polyethylene and crosslinked polyetylene insulated are adopted in insulation.But the problem that exists is, many of upgrade of rural power grids once-pavings, and some requires large span, and aluminium alloy conductor price is too high, and the aerial cable of former national Specification can't be satisfied the demand.
Summary of the invention
The utility model be intended at existing aerial cable exist can not the large span once-paving many defective, the big span laying of a kind of energy, low, the safe antitheft of cost are provided, have the collapsible bundle assembled aerial cable of bearing structure, used with upgrade of rural power grids preferably.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is as follows:
A kind of collapsible built on stilts cable with bearing structure, constitute single insulated wire cores by conductor and insulating layer of conductor, many cores are extruded stranding, it is characterized in that: the conductor middle part of single insulated wire cores is individual wire or steel strand wire, its skin is to press aluminium conductor, and the described aluminium conductor that presses is pressed by many aluminum steel single or multiple lifts and forms.
The utility model constitutes cable by three cores or four-core insulated wire cores, and the insulated wire cores combination is amounts to square, star-like or yi word pattern, and adjacent two insulated wire cores closely bond or adopt connecting band to connect.
An extrusion molding of the insulating barrier of the utility model insulated wire cores and connecting band.
Insulating layer of conductor 6 described in the utility model is made of the outer weather-proof polyvinyl chloride of one deck that extrude of combined conductor 5 or polyethylene or crosslinked polyethylene insulation material.
The beneficial effects of the utility model show:
One, conductor inside has been set up the steel wire of bearing structure or steel strand wire and skin and is pressed aluminium conductor and constituted combined conductor, has increased the tensile strength of conductor, has increased the laying distance;
Two, three cores and four-core connect, and many of once-pavings have further increased the whole tensile strength of cable, have improved production efficiency, have reduced laying and production cost;
Three, core has adopted the folding structure stranding, is convenient to lay.

Embodiment
A kind of collapsible built on stilts cable with bearing structure, constitute single insulated wire cores by conductor 5 and insulating layer of conductor 6, many cores are extruded stranding, the conductor 5 of single insulated wire cores adopts has the combined conductor form of bearing structure, can select following two kinds for use, one is: individual wire 1 is adopted at the middle part, and the outside individual layer that adopts presses aluminium conductor 2 (as Fig. 1); It two is: steel strand wire 3 are adopted at the middle part, and the outside bilayer that adopts presses aluminium conductor 2 (as Fig. 2), and the employing of steel wire 1 or steel strand wire 3 makes the tensile strength of cable improve greatly, and saved production cost.
Described insulating layer of conductor 6 is made of the outer weather-proof polyvinyl chloride of one deck that extrude of combined conductor 5 or polyethylene or crosslinked polyethylene insulation material.
The utility model constitutes cable by three cores or four-core insulated wire cores, and the insulated wire cores combination is amounts to square, star-like or yi word pattern, and adjacent two insulated wire cores closely bond or adopt connecting band 7 to connect.
Among Fig. 3 and Fig. 4, amount to insulating barrier and 7 extrusion moldings of connecting band of square and yi word pattern quad, up and down or two pairs of cores of the right and left closely bond, middle two cores adopt connecting band 7 to connect.
Among Fig. 5 and Fig. 6, insulating barrier and 7 extrusion moldings of connecting band of star-like and yi word pattern three-core cable.Wherein a pair of core closely bonds, and another adopts connecting band 7 to connect to core.
