Description

A kind of silicon rubber high-temperature resistant power cable

Technical field

The utility model is related to field of cables, and in particular to a kind of silicon rubber high-temperature resistant power cable.

Background technology

With the development of society, the demand of cable is increasing, the field being related to is more and more wider, the electricity in some fields Cable needs cable to possess extraordinary resistance to elevated temperatures on, if the conductor especially inside cable conductor is chronically at height Among warm environment, situations such as damage occurs in conductor, so as to cause the electric property of cable, signal transmission performance etc. by very big Influence, it is impossible to continue to meet use requirement.

The content of the invention

Goal of the invention：In order to overcome the deficiencies in the prior art to possess good heat-proof quality, conductor there is provided one kind The good silicon rubber high-temperature resistant power cable of temperature environment.

Technical scheme：To achieve the above object, the utility model provides a kind of silicon rubber high-temperature resistant power cable, including cable Core, the cable core is coated with thermal insulation layer, screen layer, insulating barrier, high-temperature resistant coating layer and silicone rubber jacket layer successively from inside to outside, The cable core includes two conductors and the cable core in filling cable core space is filled, and it is heat-insulated to be additionally provided with triangular form in the cable core Frame, described two conductors are respectively positioned in triangular form trivet, and three ends angle of the triangular form trivet is both connected to thermal insulation layer Inwall on, the conductor is coated with insulating layer of conductor, and the insulating layer of conductor is coated with conductor thermal insulation layer, the silicon rubber shield The outer surface of jacket layer is provided with some evenly distributed fin.

Further, the thermal insulation layer is nanometer micropore insulation material layer.

Further, the triangular form trivet is the heat-insulated board mounts of EPE, and EPE thermal insulation boards possess fabulous heat-proof quality, Good effect of heat insulation can be played to conductor, so as to reduce the temperature in use of conductor.

Beneficial effect：Compared with prior art, fin, high-temperature resistant coating layer and thermal insulation layer can be successively for the utility model The outside heat entered in cable conductor is balanced out, so that possess good temperature environment inside cable core, triangular form in addition Trivet further can fall the heat entered inside the cable core of part in triangular form trivet by baffle again, so as to more optimize The temperature in use environment of conductor so that cable possesses good resistance to elevated temperatures, it is ensured that conductor is in higher external temperature It is capable of the use of normal continuous in environment, the using effect of cable has obtained effective guarantee, and extends the use of cable Life-span.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with the accompanying drawings and specific embodiment, the utility model is further elucidated, it should be understood that these embodiments are only used for Illustrate the utility model rather than limit scope of the present utility model, after the utility model has been read, art technology Modification of the personnel to the various equivalent form of values of the present utility model falls within the application appended claims limited range.

As shown in figure 1, the utility model provides a kind of silicon rubber high-temperature resistant power cable, including cable core 1, the cable core 1 It is coated with thermal insulation layer 2, screen layer 3, insulating barrier 4, high-temperature resistant coating layer 5 and silicone rubber jacket layer 6, the cable successively from inside to outside Core 1 includes being additionally provided with triangular form trivet in the cable core filling 9 in two conductors 7 and filling cable core 1 space, the cable core 1 8, described two conductors 7 are respectively positioned in triangular form trivet 8, and three of the triangular form trivet 8 ends angle is both connected to heat-insulated On the inwall of layer 2, the conductor 7 is coated with insulating layer of conductor 71, and the insulating layer of conductor 71 is coated with conductor thermal insulation layer 72, institute The outer surface for stating silicone rubber jacket layer 6 is provided with some evenly distributed fin 10, and the thermal insulation layer 2 is that nanometer micropore is heat-insulated Material layer, the triangular form trivet 8 is the heat-insulated board mounts of EPE.

The utility model intermediate cam type trivet 8 is not only able to play a part of being thermally shielded conductor, and can carry The bulk strength of high cable core 1 so that cable core 1 is not susceptible to modification.
