Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment technology, to the accompanying drawing of required use in embodiment technical description be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Numeral and the represented corresponding component title of letter in figure:
1. composite core 2. stranded conductor 3. semiconductive shielding layer 4. weather insulating barrier 5. fluorescence radiation colour bands.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of aerial insulated cable of the present utility model, aerial insulated cable comprises composite core 1, stranded conductor 2, semiconductive shielding layer 3 and weather insulating barrier 4 from the inside to the outside successively, aerial insulated cable also comprises fluorescence radiation colour band 5, and fluorescence radiation colour band 5 is along the axis direction setting of weather insulating barrier 4; Composite core 1 is any one or combination in any of high-strength carbon fiber composite core, basalt composite core, aramid fiber composite core.
Aerial insulated cable of the present utility model is provided with one and divides colour band 5 along insulating barrier axis direction the fluorescence radiation that extends to insulating barrier two ends on the outer wall of weather insulating barrier 4, fluorescence radiation divides the colour band 5 can be luminous under the environment of dark or insufficient light, the position that demonstrates cable of image, make people can see intuitively cable position clearly in daily productive life, be convenient to effectively avoid cable line, in order to avoid damage cable, also prevent from being hindered by impaired cable, more to related works such as the maintenance under dark surrounds, repairing and maintenances, provide convenience.
Composite core be single or many stranded.Its tensile strength is up to 2399MPa, make the tensile strength of whole insulated cable far away higher than existing aluminium alloy conductor insulated aerial cable and steel reinforced aluminium conductor conductor wire core aerial insulated cable, built on stilts span is about large 10～50 times of common suspended insulated guide wire, not only save a large amount of shaft towers, and the reduction of erection time, sapce charge, human cost, equipment cost etc. have greatly been saved, simultaneously because strengthening core is nonmagnetic substance, during operation, do not produce magnetic loss, also can be every year country and save many coals, water equal energy source.
Stranded conductor 2 is formed by many annealed aluminium wire concentric strandings.The activity coefficient of stranded conductor 2 is not less than 94%.Stranded leading of the present utility model adopts conductance to be not less than the annealed aluminium wire concentric stranding of 63%IACS, activity coefficient is not less than 94%, single line annealed aluminium wire cross section is greater than common round aluminum steel, under diameter same case, the many 28 % left and right of the common round line compact conductor of annealed aluminium molded line stranded conductor aluminium section ratio, when area is identical, the common round line compact conductor of annealed aluminium molded line stranded conductor aluminium section ratio is much smaller, radical is far fewer than circle aluminum steel, not only can save a large amount of inner shields and Insulation Material, die cost, wire drawing, joint, storage, carrying, the upper machine time, and equipment cage number and dish number are required to require so strict not as circle line, and the conductance of the round aluminum steel of the conductance of annealed aluminium molded line is high more than 2%.The activity coefficient that stranded conductor is high, make conductor structure more closely knit, size uniform, telogenesis is smooth, can not only effectively stop water along the longtitudinal dispersion of insulated cable, and make cable electric field more even, and reduce the shortcomings such as conventional aluminum compact conductor surface and oil contaminant is many, burr is many, gap is large, improve the electrical safety performance of insulated cable.
Weather insulating barrier 4 is made by 150 ℃ of black weatherability IXPE overhead insulating materials.Common aerial insulated cable is owing to being subject to the restriction of aluminium core or the loss of steel reinforced aluminium conductor conductor wire core tensile strength, its long-time running temperature is only 70～90 ℃, therefore the long-time running temperature of cable can reach 150 ℃, cable transmission capacity is about conventional aluminium core or steel reinforced aluminium conductor conductor wire core aerial insulated cable transmission capacity 1.8～22 times, because transmission capacity is large, can reduce by the cable line feeder number of 1 times, can save the air corridor of 1 times.
Adopt the beneficial effect of the technical program to be: can be under the environment of dark or insufficient light can self be luminous, make people can see intuitively cable position clearly in daily productive life, be convenient to effectively avoid cable line, in order to avoid damage cable, also prevent from being hindered by impaired cable, more to related works such as the maintenance under dark surrounds, repairing and maintenances, provide convenience; High strength, transmission capacity is large, and long service life is saved a large amount of shaft towers, and the reduction of erection time, has greatly saved sapce charge, human cost.
