Description
Technical field
The utility model patent belongs to technical field of electric wires and cables, is specifically related to a kind of 10kV parallel bunched overhead insulated cable.
Background technology
At present, China's overwhelming majority aerial insulated cable is single-core cable, and this is relevant with the application model of the low voltage power distribution network of China.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 the power consumption of each user is extremely uneven, cause in its basic routing line and produce obvious line loss, sometimes line loss reaches more than 25% unexpectedly, causes great energy waste.Three cores of existing domestic production, the factory of four-core strand type aerial cable are more.But because the stranded aerial insulated cable tensile strength of multicore is not enough, in installation and more difficult in laying, branch draws connection technology and does not pass a test, so can not promote very well always.Therefore existing single-core cable tensile strength is not enough, the large problem of line loss to need a kind of overhead cable to solve.
Utility model content
The utility model is for the deficiencies in the prior art, and existing single-core cable tensile strength is not enough, the large problem of line loss to provide a kind of 10kV parallel bunched overhead insulated cable of dependable performance to solve, and cost is low, good weatherability.
The technical solution of the utility model is achieved in that and comprises three sub-cables, by the parallel connection of dowel between each sub-cable, it is characterized in that, described sub-cable comprises strengthening core, the arranged in co-axial alignment conductor outside strengthening core and the conductor shield be coated on outside conductor; Described conductor shield outside is also provided with the insulating barrier that cross section is fluted disc shape.
Described conductor is that the shaping single line strand system of the hard aluminum or aluminum alloy of some employings forms; The cross section of this conductor is circular or trapezoidal.
Described insulating barrier is made up of the weather-proof crosslinked polyethylene insulation material of black, its thickness 2.5 ~ 3.5mm.
Described strengthening core is many steel wires or steel strand wire.
Described conductor shield is that cross-linking type conductor screen material is made, its thickness 0.5 ~ 1mm.
Described three sub-cables and dowel pass through injection moulding integrated molding.
Described three sub-cables are provided with corresponding phase sequence mark.
The utility model solves the defect existed in background technology, has following beneficial effect:
(1) construction of cable optimized is adopted.Conductor adopts the shaping single line of hard aluminum or aluminum alloy strand system to form, centre steel wire or steel strand wire as strengthening core, improve largely cable tensile strength.
(2) current-carrying capacity of cable is improved.The surface of insulating layer of fluted disc shape, increases cable surface area, significantly improves the heat-sinking capability of cable surface, contributes to the raising that cable runs ampacity, compares ampacity improve about 5 ~ 10% with existing same conductor material with the aerial cable in cross section.
(3) insulation adopts the weather-proof cross-linked polyethylene insulating material of black, can be fire-retardant, prevents electric leakage.Between insulation and conductor, conductor shield is set, avoids, between conductor and insulating barrier, partial discharge occurs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-strengthening core, 2-conductor, 3-conductor shield, 4-insulating barrier, 5-dowel.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
10kV parallel bunched overhead insulated cable as shown in Figure 1, comprise three sub-cables, by the parallel connection of dowel 5 between each sub-cable, sub-cable comprises strengthening core 1, the arranged in co-axial alignment conductor 2 outside strengthening core 1 and the conductor shield 3 be coated on outside conductor 2; Conductor shield 3 outside is also provided with the insulating barrier 4 that cross section is fluted disc shape.The shaping single line strand system that conductor 2 is the hard aluminum or aluminum alloy of some employings forms; The cross section of this conductor 2 is circular or trapezoidal.Insulating barrier 4 is made up of crosslinked polyolefin materials, its thickness 2.5 ~ 3.5mm.Strengthening core 1 is many steel wires or steel strand wire.Conductor shield 3 is made for cross-linking type conductor screen material, its thickness 0.5 ~ 1mm.Three sub-cables and dowel 5 pass through injection moulding integrated molding.Three sub-cables are provided with corresponding phase sequence mark.
The utility model implementation process is: conductor 2 adopts the shaping single line of hard aluminum or aluminum alloy strand system to form, centre steel wire or steel strand wire as strengthening core 1, improve largely cable tensile strength.The surface of insulating layer of fluted disc shape, increase cable surface area, significantly improve the heat-sinking capability of cable surface, contribute to the raising that cable runs ampacity, compare ampacity with existing same conductor material with the aerial cable in cross section and improve about 5 ~ 10%, current-carrying capacity of cable is improved.Insulating barrier 4 adopts the weather-proof cross-linked polyethylene insulating material of black, and cross-linked polyolefin has remarkable combustion characteristics and mechanical performance, insulation resistance also can not be made significantly to reduce even if make moist, and has thoroughly stopped the possibility of leaking electricity.Conductor shield 3 is set between insulating barrier 4 and conductor 2, avoids, between conductor and insulation, partial discharge occurs.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
