Abstract
Disclosed is a high-strength steel-cored aluminum stranded wire crosslinked polyethylene insulation aerial cable, mainly solving the problems that conventional insulation aerial cables using aluminum conductor core wires are low in tensile strength and that conventional insulation aerial cables using steel conductor core wires are relatively high in resistivity. The cable comprises a core wire (1) and an insulating layer (2). The insulating layer (2) is tightly coated outside the core wire (1). The cable is characterized in that the core wire (1) is formed by intertwisting a plurality of steel wires (3), and the outer wall of each steel wire is provided with an aluminized layer (4). The cable is characterized by being high in tensile strength, low in resistivity, and low in cost.
Description
Technical field
The utility model relates to a kind of insulated aerial cable, is specifically related to a kind of high strength steel core aluminum stranded wire crosslinked polyethylene insulated aerial 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.Existing insulated aerial cable heart yearn generally adopts conventional aluminium conductor, steel conductor or copper conductor, and aluminium conductor heart yearn cable tensile strength is low, can not grow the built on stilts of distance and lay; Steel conductor core wire cable resistance rate is larger, and loss is large; Copper conductor heart yearn cable cost is high, is not suitable for long the built on stilts of distance and lays.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of high strength steel core aluminum stranded wire crosslinked polyethylene insulated aerial cable, and this cable has tensile strength height, resistivity is little and cost is low characteristics.
The technical solution of the utility model is: this high strength steel core aluminum stranded wire crosslinked polyethylene insulated aerial cable, comprise heart yearn and insulating barrier, and insulating barrier closely is coated on outside the heart yearn, and heart yearn is by many stranded the forming of steel wire, and the outer wall of steel wire is provided with aluminium coated.
Described steel wire is 7 or 19.
Described insulating barrier is crosslinked polyethylene.
The beneficial effects of the utility model are: owing to take such scheme, steel wire has improved the tensile strength of heart yearn, because CHARGE DISTRIBUTION is mainly at the outer surface of conductor, therefore aluminium coated has effectively reduced the resistivity of heart yearn, the utility model is compared with background technology, has drawn the advantage of aluminium conductor heart yearn and steel conductor core wire, existing higher tensile strength, improved again electric conductivity, cost is lower simultaneously.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is structure cutaway views of heart yearn 1 among Fig. 1.
1-heart yearn among the figure, 2-insulating barrier, 3-steel wire, 4-aluminium coated.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Figure 1 and Figure 2, this high strength steel core aluminum stranded wire crosslinked polyethylene insulated aerial cable comprises heart yearn 1 and insulating barrier 2, and insulating barrier 2 closely is coated on outside the heart yearn 1, and heart yearn 1 is by many steel wires 3 stranded forming, and the outer wall of steel wire 3 is provided with aluminium coated 4.Owing to take technique scheme, steel wire 3 has improved the tensile strength of heart yearn 1, because CHARGE DISTRIBUTION is mainly at the outer surface of conductor, therefore aluminium coated 4 has effectively reduced the resistivity of heart yearn 1, the utility model is compared with background technology, has drawn the advantage of aluminium conductor heart yearn and steel conductor core wire, existing higher tensile strength, improved again electric conductivity, cost is lower simultaneously.
Described steel wire 3 is 7 or 19.The quantity of steel wire 3 is determined according to conductive capability.
Described insulating barrier 2 is crosslinked polyethylene.Insulating barrier 2 adopts conventional insulating material, and cost is lower.
