Abstract

A lighting-used overhead insulated cable is provided. The lighting-used overhead insulated cable comprises wire cores I (1) set as power transmission lines, a wire core II (2) set as a lighting line, a wire core III (3) which is set as a neutral line and has steel wires adopted as core bodies; three strands of wire cores I (1) exist; and the centers of the wire cores I (1), the center of the wire core II (2) and the center of the wire core III (3) are arranged on a sealing wire sequentially and are integrated through stranding. The wire cores I (1) are adopted as the power transmission lines, the wire core II (2) is adopted as the lighting line, and the wire core III (3) is adopted as the neutral line, and therefore, the strength of the overhead insulated cable can be enhanced.

Description

For the aerial insulated cable throwing light on

One, technical field

The utility model relates to a kind of aerial insulated cable, especially a kind of aerial insulated cable for throwing light on.

Two, background technology

Cable is widely used in electric power system, signal transmission, instrument system and various product, therefore for the aerial insulated cable throwing light on, be a kind of important power components, at the existing aerial insulated cable for throwing light on, generally stranded by the monofilament of copper or aluminium drawing, extruded insulation is made, and laying of this aerial insulated cable, generally adopts equidirectional level or delta arrangement to lay, need certain space, and exist larger tree line contradiction; And multicore aerial insulated cable is just stranded by two cores or four-core core aborning, because the intensity of aerial insulated cable is low, can not be applied in the occasion of farmland, mine, power plant and sleet environment that wind-force is larger.

Three, summary of the invention

In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of aerial insulated cable for throwing light on, and has therefore strengthened the intensity of aerial insulated cable.

For achieving the above object, the technical scheme that the utility model is taked is: include be set to power transmission line core I, be set to illuminating line core II, be set to the neutral line and there is the core III that steel wire is core body, core I is set to three strands, and core Ⅰ center and core Ⅱ center and core Ⅲ center are successively set on a sealing lines and are set to and integrate by stranded mode.

Owing to having designed core I, core II and core III, use core I as power transmission line, core II, as illuminating line, is used core III as the neutral line, has therefore strengthened the intensity of aerial insulated cable.

The utility model has designed, and it is that insulator endosome are stranded aluminium conductor that core I is provided with skin, and it is that insulator endosome are aluminium alloy conductor that core II is provided with outer, and it is that insulator endosome are steel reinforced aluminium conductor conductor that core III is provided with outer.

The utility model has designed, and insulator is set to the insulator that 70 ℃ of weather-proof polyvinyl chloride of black, black weather-resistance polyethylene or the weather-proof crosslinked polyethylene of 1kV black are made.

Useful technique effect of the present utility model is: in insulated wire cores, comprise that three cores press stranded aluminium insulated wire cores; One core aluminum alloy insulated wire core; One core compacting pressing steel reinforced aluminium conductor insulated wire cores.Insulation all adopts weather resistant overhead insulating.Three core power transmission lines and a neutral line, an illuminating line, five single core aerial cable cores twist together, and for built on stilts, lay, and from appearance, see it is a cable, have easy construction, saving of work and time, the advantage of reduction operating expenses, project cost is low.Illumination core is used aluminium alloy conductor, has higher conductivity and tensile strength, can adaptating lighting circuit.Neutral core adopts steel reinforced aluminium conductor conductor, has stronger tensile strength, has removed neutral core effect, also plays and increases the effect of cable intensity.Due to above-mentioned technical characterictic, conductor wire core is stranded steel-cored aluminum strand core, the disconnected more former aerial cable of power of the Chinese People's Anti-Japanese Military and Political College is multiplied, and reduces broken string accident.Operating safety factor improves, and anti-lightning strike, anti-electricity-theft, strong wind sleet environmental effect are obviously improved.The stranded illumination core of aluminium alloy conductor, according to zero line sign, phase sequence identification is clear, prevents misconnection phase sequence.Save the shared space of overhead transmission line, improved power distribution system secure reliability.

In the technical program, have some strength core III 3 and with the Rankine-Hugoniot relations of core I 1 and core II 2 be important technical characterictic, in the technical field of the aerial insulated cable for throwing light on, there is novelty, creativeness and practicality.

Four, accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model.

Five, embodiment

Fig. 1 is first embodiment of the present utility model, illustrate by reference to the accompanying drawings the present embodiment, include core I 1, core II 2 and core III 3, it is that insulator endosome are stranded aluminium conductor that core I 1 is provided with outer, it is that insulator endosome are aluminium alloy conductor that core II 2 is provided with outer, it is that insulator endosome are steel reinforced aluminium conductor conductor that core III 3 is provided with outer, core I 1 is set to three strands, and the center of the center of core I 1 and core II 2 and the center of core III 3 are successively set on a sealing lines and are set to and integrate by stranded mode.

In the present embodiment, insulator is set to 70 ℃ of weather-proof polyvinyl chloride of black.

Using compenzine core I 1 as power transmission line, using core II 2 as illuminating line, using core III 3 as the neutral line, thereby as illumination aerial insulated cable.

Second embodiment of the present utility model, insulator is set to black weather-resistance polyethylene.

The 3rd embodiment of the present utility model, insulator is set to the insulator that the weather-proof crosslinked polyethylene of 1kV black is made.

The utlity model has lower feature:

1, owing to having designed core I 1, core II 2 and core III 3, use core I 1 as power transmission line, use core II 2 as illuminating line, use core III 3 as neutral line core, therefore strengthened the intensity of aerial insulated cable.

2,, owing to having designed core I 1, core II 2 and core III 3, good insulation preformance, has improved the security performance of illumination.

3, owing to having designed core I 1, core II 2 and core III 3, avoided generation tree line contradictory phenomena.

In the aerial insulated cable technical field for throwing light on; Every include be set to power transmission line core I 1, be set to illuminating line core II 2, be set to the neutral line and there is the core III 3 that steel wire is core body; core I 1 is set to three strands, the center of the center of core I 1 and core II 2 and the center of core III 3 be successively set on a sealing lines and the technology contents that is set to integrate by stranded mode all in protection range of the present utility model.
