Description

A kind of cable

Technical field

This utility model relates to electrical equipment technical field, particularly to a kind of cable。

Background technology

When transmitting electric power, the conductor of high voltage power cable generates heat。Transmit this heat by the insulating material being arranged in around conductor, and due to these thermal losses, the temperature around cable increases。Conductor is mostly by copper or what aluminum was made, and insulating material referred herein can be polymerization, and generally includes crosslinked polyethylene or oil impregnated paper insulant。If the temperature of conductor does not maintain in the interval of restriction, the heat generated in the conductor may result in insulant and degenerates。

Additionally, existing power cable is solid cable, having that weight is big, the outer problems such as junction is little, resistance is big, temperature rise is fast, heat dispersion is poor of conductor, additionally, due to electric current kelvin effect, cause current-carrying capacity of cable little, the existence of eddy current causes electric energy loss big。Simultaneously as existing cable temperature rise is fast, its cable insulation is easily aging, restriction cable service life。Solid cable uses metal material many, and cable weight is big, and difficulty of construction during installation is bigger。

Utility model content

The technical problems to be solved in the utility model is to provide a kind of good heat dissipation, lightweight cable, and this cable can be used for high-tension electricity conveying。

In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that a kind of cable, including rubber sheath, armor, obturator and some cable cores, described cable core is embedded in obturator, described armor wraps the outer peripheral face of obturator, described rubber sheath is sheathed on the outside of armor, described cable core includes insulator, braided fiber reinforcing layer and the cross section conductor in " C " font, described conductor is embedded in insulator, described braided fiber reinforcing layer wraps the outer peripheral face of insulator, the outside of described braided fiber reinforcing layer is wound with the first graphite radiating film, described obturator is also embedded with cooling core, described cooling core offers cooling liquid flowing channel。

Additionally, the outer peripheral face of described cooling core is wound with the second graphite radiating film, the outer surface of described second graphite radiating film abuts against the outer surface of the first graphite radiating film。

Wherein, described cooling core is also embedded with some nylon ropes。

Preferably, described cooling core is made up of boron nitride heat conductive rubber。

Preferably, described braided fiber reinforcing layer is formed by Fanglun 1414's braiding。

What this utility model obtained has the beneficial effects that: the cable that this utility model provides have employed the conductor of inner hollow, this structure both ensure that the ability to transmit electricity of cable, significantly alleviate again the weight of cable, also expand the area of dissipation of conductor simultaneously, improve the heat dispersion of cable, significantly, this utility model is wound around one layer of graphite radiating film the outside of cable core, accelerate the speed that heat produced by conductor transmits outward, further, by arranging cooling core inside cable, cooling core is offered cooling liquid flowing channel, cooling effect by coolant (can be such as water or oil), make cable internal temperature can be always held at relatively low state, thus it is too high to avoid cable temperature in high voltage power transmission process, the situation that insulant is aging。

Detailed description of the invention

For the ease of the understanding of those skilled in the art, below in conjunction with embodiment and accompanying drawing, this utility model being further described, the content that embodiment is mentioned is not to restriction of the present utility model。

In description of the present utility model, it will be appreciated that, term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width ", " thickness ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", " outward ", " clockwise ", orientation or the position relationship of the instruction such as " counterclockwise " are based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model and simplifies description, rather than the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model。

Additionally, term " first ", " second " are only for descriptive purposes, and it is not intended that indicate or imply relative importance or the implicit quantity indicating indicated technical characteristic。In description of the present utility model, " multiple " are meant that two or more, unless otherwise expressly limited specifically。

As shown in Figure 1-2, a kind of cable, including rubber sheath 1, armor 2, obturator 3 and some cable cores 4, cable core 4 is embedded in obturator 3, armor 2 wraps the outer peripheral face of obturator 3, rubber sheath 1 is sheathed on the outside of armor 2, cable core 4 includes insulator 41, braided fiber reinforcing layer 42 and the cross section conductor 43 in " C " font, conductor 43 is embedded in insulator 41, braided fiber reinforcing layer 42 wraps the outer peripheral face of insulator 41, the outside of braided fiber reinforcing layer 42 is wound with the first graphite radiating film 44, obturator 3 is also embedded with cooling core 5, cooling core 5 offers cooling liquid flowing channel 51。

In the present embodiment, cable have employed the conductor of inner hollow (namely cross section is " C " font), this structure both ensure that the ability to transmit electricity of cable, significantly alleviate again the weight of cable, also expand the area of dissipation of cable simultaneously, improve the heat dispersion of cable, significantly, the present embodiment is wound around one layer of graphite radiating film the outside of cable core 4, accelerate the speed that heat produced by conductor 43 transmits outward, further, by arranging cooling core 5 inside cable, cooling core 5 is offered cooling liquid flowing channel 51, cooling effect by coolant (can be such as water or oil), make cable internal temperature can be always held at relatively low state, thus it is too high to avoid cable temperature in high voltage power transmission process, the situation that insulant is aging。

On the basis of such scheme, further, it is also possible to the outer peripheral face at cooling core 5 is wound around the second graphite radiating film 52, the outer surface of this second graphite radiating film 52 is abutted against the outer surface of the first graphite radiating film 44。

The speed that heat produced by conductor 43 transmits can be further speeded up toward cooling core 5, it is possible to avoid the situation that conductor 43 temperature is too high better by being wound around the second graphite radiating film 52 at the outer peripheral face of cooling core 5。

Further, it is also possible to be embedded some nylon ropes 53 in cooling core 5。

Cooling core 5 is embedded nylon rope 53 and can improve the tensile strength of cable, the weight of cable will not be increased, it is possible to be effectively ensured the service life of cable simultaneously。
