To achieve the above object, the utility model provides the following technical solutions: a kind of high-temperature-resistant power cable, including master Body, the main body are internally provided with wire body, and the middle position of body interior is provided with reinforcing rib, the reinforcing rib it is outer Side is provided with the thermal column through main body, and the inside of the main body is filled with heat-conducting layer, and reflective layer is provided on the outside of main body, It is provided with the first glass layer on the inside of the reflective layer, and is provided with the first insulating layer on the inside of the first glass layer, It is provided with the first fireprotection layer on the inside of first insulating layer, the second fireprotection layer is provided on the outside of the wire body, and second is anti- It is provided with the second glass layer on the inside of fire bed, is provided with second insulating layer on the inside of second glass layer.

Preferably, the number of the thermal column is three groups, is provided at the position of thermal column described in three groups and body contact Water expandable waterstop.

Preferably, the material of first fireprotection layer and the second fireprotection layer is fire prevention ooze.

Preferably, the number of the wire body is three groups, and wire body described in three groups is equidistantly distributed with thermal column described in three groups.

Preferably, the material of the reflective layer is aluminium-foil paper.

Compared with prior art, the utility model has the beneficial effects that the utility model is by the heat-conducting layer of setting by three The heat that group wire body generates is respectively transmitted to main body and thermal column, and main body carries out level-one heat dissipation, and thermal column is by heat Quick diffusing It goes out, realizes two-class heat dissipation, so that this kind of power cable can work long hours, the reflective layer of setting can reduce the sun The illumination of light, not only can reduce the damage of main body, while can reduce the heat of absorbent body, so that improving this kind of cable makes Safety.

Fig. 2 is the schematic diagram of internal structure of the utility model.

In figure: 1, main body；2, thermal column；3, wire body；4, reinforcing rib；5, reflective layer；6, the first glass layer；7, water is met Expansion sealing strip；8, the first fireprotection layer；9, heat-conducting layer；10, second insulating layer；11, the second fireprotection layer；12, the second glass fibre Layer；13, the first insulating layer.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

A kind of high-temperature-resistant power cable referring to FIG. 1-2, including main body 1, main body 1 are internally provided with wire body 3, and main Middle position inside body 1 is provided with reinforcing rib 4, and the outside of reinforcing rib 4 is provided with the thermal column 2 through main body 1, main body 1 Inside be filled with heat-conducting layer 9, and the outside of main body 1 is provided with reflective layer 5, and the inside of reflective layer 5 is provided with the first glass fibers Layer 6 is tieed up, and the inside of the first glass layer 6 is provided with the first insulating layer 13, the inside of the first insulating layer 13 is provided with first Fireprotection layer 8, the outside of wire body 3 is provided with the second fireprotection layer 11, and the inside of the second fireprotection layer 11 is provided with the second glass fibre Layer 12, the inside of the second glass layer 12 is provided with second insulating layer 10.

The heat that three groups of wire bodies 3 generate is respectively transmitted to main body 1 and is reinforced by the heat-conducting layer 9 of setting by the utility model Muscle 4, main body 1 carry out level-one heat dissipation, and thermal column 2 goes out heat Quick diffusing, two-class heat dissipation are realized, so that this kind of electric power Cable can work long hours.

Please be emphatically refering to fig. 1 with 2, the number of thermal column 2 is three groups, is set at the position that three groups of thermal columns 2 are contacted with main body 1 It is equipped with water expandable waterstop 7, the number of wire body 3 is three groups, and three groups of wire bodies 3 are equidistantly distributed with three groups of thermal columns 2.

The three groups of thermal columns 2 and three groups of interactions of wire bodies 3 of this kind of high-temperature-resistant power cable by setting, can quickly by Heat quickly passes, the water expandable waterstop 7 of setting, can be to avoid 1 inner inlet of main body.

Please be emphatically refering to fig. 1 with 2, the material of the first fireprotection layer 8 and the second fireprotection layer 11 is ooze of preventing fires, reflective layer 5 Material is aluminium-foil paper.

The material that this kind of high-temperature-resistant power cable passes through setting is the first fireprotection layer 8 and the second fireprotection layer of fire prevention ooze 11, can be to avoid wire body 3 and main body 1 because of the excessively high phenomenon for causing nature of temperature, the material of setting is the reflective layer 5 of aluminium-foil paper Main body 1 can be greatly reduced and absorb sunlight, and then reduce the heat of main body 1.

Working principle: the reflective layer 5 of setting makes main body 1 work outside for a long time, can reduce illumination to the damage of main body 1 Evil, while reducing the heat of absorption, the reinforcing rib 4 of setting can increase the toughness of main body 1, the heat warp that three groups of wire bodies 3 generate It crosses heat-conducting layer 9 and quickly passes to thermal column 2, thermal column 2 goes out heat Quick diffusing, and the water expandable waterstop 7 of setting is kept away Exempt to enter water source inside main body 1, the first insulating layer 13 and second insulating layer of setting avoid occurring electricity between main body 1 and wire body The phenomenon that source leaks, so that safe using more using, the first fireprotection layer 8 and the second fireprotection layer 11 of setting avoid temperature mistake Height causes natural phenomena, the first glass layer 6 and the second glass layer 12 of setting, increases the tough of main body 1 and wire body 3 Property.

It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting Related claim.
