Problems solved by technology

[0002] When the power cable is transmitting power, the core conductor of the cable will heat up under the action of its own resistance due to the large current passing through it. The longer the time, the higher the temperature, the greater the resistance, the easier it is to heat up, causing power transmission loss; if the conductor The temperature cannot be controlled within a limited temperature range, and the heat generated by the conductor may cause the degradation of the insulating material, resulting in safety accidents such as cable damage and fire
At present, the main way to control the temperatur...

Example Embodiment

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0017] see Figure 1-2 , In the embodiment of the present invention, a heat dissipation, flame retardant and break-proof power cable includes a core wire 1 and a protective layer 4, and the inner ring of the protective layer 4 is provided with an outer steel tape armor layer 3 and The outer shielding layer 2; the outer ring of the protective layer 4 is provided with a warning layer 5 and a warning layer protective cover 6 layer by layer, and the provided warning layer protective cover 6 plays the role of warning and protection. The warning material of the warning layer 5 will display color when exposed to light to warn the construction workers. The following are the cables. The warning layer protective cover 6 provided has the first layer of protection. When the construction workers protect the warning layer of the cables When the sleeve 6 is damaged, the warning layer 5 will leak out, indicating that the following is the cable, please do not construct or detour.
[0018] The cavity formed between the outer shielding layer 2 and the outer ring of the core wire 1 is filled with a wire core filling strip 8, and the wire core filling strip 8 is made of thermally conductive silica gel, so that it has good heat transfer performance. Three heat dissipation holes 7 are provided in the wire core filling bar 8 made of thermally conductive silica gel, and the heat dissipation holes in turn form heat dissipation channels.
[0019] The core wire 1 includes a conductor bundle 11, an insulating layer 12, an inner shielding layer 13, an inner steel tape armor layer 14 and a flame retardant layer 15. The outer ring of the conductor bundle 11 is provided with an insulating layer 12. The cavity formed between them is filled with insulating fillers, and the insulating fillers are made of water-blocking materials; the conductor bundles 11 are composed of copper wires; the outer ring of the insulating layer 12 is provided with an inner shielding layer 13, which The outer ring of the layer 13 is provided with an inner steel tape armor layer 14, which greatly enhances the strength of the core wire 1 itself. Even if the outer steel tape armor layer 3 of the outer layer is accidentally broken, the inner steel tape armor layer of the inner layer 14 can also make the core wire 1 have a certain strength, so as to ensure normal power supply; the outer ring of the inner steel tape armoring layer 14 is provided with a flame retardant layer 15 .
[0020] It will be apparent to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, but that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments are to be regarded in all respects as illustrative and not restrictive, and the scope of the invention is to be defined by the appended claims rather than the foregoing description, which are therefore intended to fall within the scope of the claims. All changes within the meaning and scope of the equivalents of , are included in the present invention. Any reference signs in the claims shall not be construed as limiting the involved claim.
[0021] In addition, it should be understood that although this specification is described in terms of embodiments, not each embodiment only includes an independent technical solution, and this description in the specification is only for the sake of clarity, and those skilled in the art should take the specification as a whole , the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
