Abstract
The utility model discloses a plum blossom-shaped insulating parallelly-bunched aerial cable. The plum blossom-shaped insulating parallelly-bunched aerial cable includes a plurality of sub cables; each sub cable comprises conductors and an insulating layer which covers the surfaces of the conductors and is plum blossom-shaped; and the sub cables are connected parallelly. Compared with the prior art, the surface of the insulating layer of each cable core is plum blossom-shaped, and therefore, the surface area of the cable can be increased, and the heat dissipation capacity of the cable can be effectively improved, and the current-carrying capacity of the operation of the cable can be effectively improved, and the heat resistance of the cable in overload can be enhanced. With the cable adopted, capacity increasing and expanding as well as consumption reduction of a circuit can be realized.
Description
Technical field
The utility model relates to electric wire and manufactures and designs field, particularly a kind of quincunx insulation parallel cluster aerial cable.
Background technology
At present, China's overwhelming majority aerial insulated cable is single-core cable, and the application model of the low voltage power distribution network of Zhe Yu China is relevant.What China mainly adopted in low-voltage network is the single-phase transport model to family, this pattern is more convenient in installation and maintenance, but because each user's power consumption is extremely uneven, cause and in its basic routing line, produce obvious line loss, sometimes line loss reaches more than 25% unexpectedly, causes great energy waste.The factory of three cores of existing domestic production, four-core strand type aerial cable is more.But because the stranded aerial insulated cable of multicore is being installed and laying middle more difficult, branch draws connection technology and does not pass a test, so can not finely promote always.
Summary of the invention
In order to address the above problem, the utility model provides a kind of quincunx insulation parallel cluster aerial cable, comprise some sub-cables, every sub-cable comprises conductor, cover conductive surface and profile is quincuncial insulating barrier, the parallel connection of described each sub-cable.
Further, each sub-cable adopts the parallel connection of dowel.
Further, the material of insulating barrier is crosslinked polyethylene or polyvinyl chloride.
Further, described conductor consists of a single metal wire or consists of with stranded being integrated of core the single metal wire of many same diameter.
Further, described sub-cable has 2～7.
Compared with prior art, the utlity model has following feature and beneficial effect:
(1) adopt the construction of cable of optimizing.By 2～7 root cable boundlings together, improved largely cable tensile strength, compare tensile strength with single core aerial cable in existing same conductor material and cross section and improve 3 times.
(2) current-carrying capacity of cable is improved.Quincuncial surface of insulating layer, has increased cable surface area, has greatly improved the heat-sinking capability of cable surface, contributes to the raising of cable operation ampacity, compares ampacity improved 1.25 times with the aerial cable in existing same conductor material and cross section.
(3) the utility model project cost is low.Due to its design feature, can reduce the use of the gold utensils such as Xian road Gan Ta ﹑ cross-arm and porcelain piece; Construct convenient, branch connection is convenient simultaneously.Because insulating can reduce shaft tower height, be not subject to trees, the complex environment impacts such as groups of building, Ke Yanqiang lays and thoroughly saves electric pole, and project cost is low.Compare project cost with the stranded aerial cable of existing same cross-sectional and can be reduced to 0.9 times.
(4) have that heat-sinking capability is strong, tensile strength great ﹑ good weatherability (minimum environment for use temperature :-35 ℃ of) ﹑ long service life (long-term use reaches: 30 years), construct affected by environment little, branch connection convenient, project cost is low, composition material environmental protection; The useful substitute products of common single core and the stranded aerial cable of multicore.

Fig. 2 is side schematic view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, the utility model comprises some sub-cables, and described each sub-cable adopts the parallel connection of dowel 3.
As shown in Figure 2, described sub-cable comprises: conductor 1, cover conductive surface and profile is quincuncial insulating barrier 2.
Described conductor 1 is drawn and to be formed by specification aluminum steel (or copper cash), can be formed or be consisted of with stranded being integrated of core the single metal wire of many same diameter by a single metal wire.
Described insulating barrier 2 is on the surface of conductor 1, to extrude one deck crosslinked polyethylene or the polyvinyl chloride insulation of formation, and insulating barrier 2 surfaces are made into quincunx.
Described each sub-cable is arranged in parallel, and adopts each other crosslinked polyethylene or igelite dowel 3 to connect.Wherein conductor can be to consist of a single metal wire, can be also that the single metal wire by many same diameter forms with stranded being integrated of core.Sub-cable sum is preferably 2～7.
The utility model can adopt special-purpose extruded mould, once extrudes moulding on existing plastic extruding machine.Product is applicable to 1KV and following overhead transmission line lays.
Compared with prior art, the utlity model has following feature and beneficial effect:
(1) adopt the construction of cable of optimizing.By 2～7 root cable boundlings together, improved largely cable tensile strength, compare tensile strength with single core aerial cable in existing same conductor material and cross section and improve 3 times.
(2) current-carrying capacity of cable is improved.Quincuncial surface of insulating layer, has increased cable surface area, has greatly improved the heat-sinking capability of cable surface, contributes to the raising of cable operation ampacity, compares ampacity improved 1.25 times with the aerial cable in existing same conductor material and cross section.
(3) the utility model project cost is low.Due to its design feature, can reduce the use of the gold utensils such as Xian road Gan Ta ﹑ cross-arm and porcelain piece; Construct convenient, branch connection is convenient simultaneously.Because insulating can reduce shaft tower height, be not subject to trees, the complex environment impacts such as groups of building, Ke Yanqiang lays and thoroughly saves electric pole, and project cost is low.Compare project cost with the stranded aerial cable of existing same cross-sectional and can be reduced to 0.9 times.
(4) have that heat-sinking capability is strong, tensile strength great ﹑ good weatherability (minimum environment for use temperature :-35 ℃ of) ﹑ long service life (long-term use reaches: 30 years), construct affected by environment little, branch connection convenient, project cost is low; The useful substitute products of common single core and the stranded aerial cable of multicore.
