Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a high-temperature resistant composite cable. Background Technology

[0002] Composite cables are multifunctional cables that integrate cable units of different functions or materials into one unit. They are mainly divided into two categories: optoelectronic composite (integrating optical fiber and power transmission) and industrial composite (enhanced mechanical properties and multifunctional integration).

[0003] However, when composite cables are used, because they are exposed to the outside world, the outer insulation layer of the cable is prone to absorbing heat and overheating under sunlight. This can easily lead to excessively high internal temperatures in the cable, potentially causing spontaneous combustion. Utility Model Content

[0004] This invention provides a high-temperature resistant composite cable, which can effectively solve the problem mentioned in the background art that when composite cables are used, the outer insulation layer of the cable is easily exposed to the outside world and generates excessive heat under sunlight, which can easily cause the internal temperature of the cable to be too high, and even cause spontaneous combustion.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant composite cable, comprising an inner conductor cable, wherein a supporting sun protection component is installed on the outer side of the inner conductor cable, and the supporting sun protection component comprises an outer insulation layer;

[0006] The inner conductor cable is wrapped with an outer insulation layer, the outer insulation layer is wrapped with a thermally conductive buffer layer, the thermally conductive buffer layer is wrapped with an outer protective layer, the outer protective layer has a spiral groove on the outside, a supporting aluminum wire is embedded inside the spiral groove, a heat dissipation groove is formed on the outside of the supporting aluminum wire, and a reflective film is adhered to the outside of the outer protective layer.

[0007] According to the above technical solution, the gaps between the inner conductor cables are filled with data cables, and the outer side of the inner conductor cables is wrapped with supporting steel wires.

[0008] According to the above technical solution, the edge of the spiral groove and the edge of the supporting aluminum wire are attached, and the outer side of the supporting aluminum wire and the outer side of the outer protective layer are aligned.

[0009] According to the above technical solution, the inner conductor cable is wrapped with an insulating protective layer on the outside, and the supporting steel wire is spirally wrapped around the outside of the insulating protective layer.

[0010] According to the above technical solution, a thermally conductive support assembly is provided inside the outer insulation layer, and the thermally conductive support assembly includes a support filling layer;

[0011] The outer insulation layer is filled with a supporting filling layer. Heat exchange grooves are uniformly formed on the outer side of the supporting filling layer near the outer insulation layer. Heat-conducting strips are embedded inside the heat exchange grooves. Reinforcing grooves are formed on the outer side of the heat-conducting strips. Reinforcing steel wires are embedded inside the reinforcing grooves.

[0012] According to the above technical solution, the outer side of the heat-conducting strip and the outer side of the supporting filling layer are arc-shaped curved surfaces of equal diameter, and the outer side of the heat-conducting strip is attached to the inner side of the outer insulation layer.

[0013] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use;

[0014] 1. Equipped with a support and sun protection component, the reflective film reflects sunlight, reducing the heat absorbed by the cable. The thermally conductive buffer layer is made of thermally conductive silicone, which, together with the supporting aluminum wire, not only supports the cable but also transfers the heat generated inside the cable to the outer insulation layer. The heat is then guided sequentially to the thermally conductive buffer layer and the supporting aluminum wire. When there is wind, the wind passes through the heat dissipation grooves, carrying away the heat and cooling the cable. The reflection of sunlight prevents excessive heat absorption and accelerates heat dissipation, thus reducing the cable temperature and preventing problems caused by overheating.

[0015] 2. A thermally conductive support assembly is provided. When the inner conductor of the cable is energized, it will generate heat. The generated heat will be transferred to the support filling layer through the support steel wire. The thermally conductive strip is made of thermally conductive silicone, which has good thermal conductivity and can accelerate the transfer of heat to the outer insulation layer. The reinforcing steel wire in the reinforcing groove increases the strength of the thermally conductive strip, further strengthening the cable and preventing the cable from being broken due to excessive tension.

[0016] 3. The sun-protective support component reflects sunlight to prevent excessive heat absorption while accelerating heat dissipation, functioning on the outside of the cable. Meanwhile, the heat-conducting support component accelerates heat dissipation from the inside of the cable, functioning within the cable itself. The combined effect of both components results in a more effective reduction of cable heat. Attached Figure Description

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figure 1-5 As shown, this utility model provides a high-temperature resistant composite cable technical solution, including an inner conductor cable 1, and a support and sun protection component 2 installed on the outside of the inner conductor cable 1. The support and sun protection component 2 includes an outer insulation layer 201, a thermally conductive buffer layer 202, an outer sheath 203, a spiral groove 204, a support aluminum wire 205, a heat dissipation groove 206, a reflective film 207, a data cable 208, and a support steel wire 209.

[0029] The inner conductor cable 1 is wrapped with an outer insulation layer 201. A thermally conductive buffer layer 202 is wrapped around the outer insulation layer 201. An outer sheath 203 is wrapped around the outer thermally conductive buffer layer 202. A spiral groove 204 is formed on the outer side of the outer sheath 203. The edge of the spiral groove 204 is attached to the edge of the supporting aluminum wire 205. The outer side of the supporting aluminum wire 205 is aligned with the outer side of the outer sheath 203 to prevent the supporting aluminum wire 205 from extending beyond the outer sheath 203 and accelerating wear. The supporting aluminum wire 205 is embedded inside the spiral groove 204. A heat dissipation groove 206 is formed on the outer side of the supporting aluminum wire 205. A reflective film 207 is adhered to the outer side of the outer sheath 203. Data cables 208 are filled in the gaps between the inner conductor cables 1. A supporting steel wire 209 is wrapped around the outer side of the inner conductor cable 1. An insulating protective layer is wrapped around the outer side of the inner conductor cable 1. The supporting steel wire 209 is spirally wrapped around the outer side of the insulating protective layer.

[0030] The outer insulation layer 201 is provided with a thermally conductive support assembly 3, which includes a support filling layer 301, a heat exchange groove 302, a thermally conductive strip 303, a reinforcing groove 304, and a reinforcing steel wire 305.

[0031] The outer insulation layer 201 is filled with a support filling layer 301. Heat exchange grooves 302 are uniformly formed on the outer side of the support filling layer 301 near the outer insulation layer 201. Heat-conducting strips 303 are embedded inside the heat exchange grooves 302. The outer side of the heat-conducting strips 303 and the outer side of the support filling layer 301 are arc-shaped surfaces of equal diameter. The outer side of the heat-conducting strips 303 is attached to the inner side of the outer insulation layer 201 to maintain the uniformity of the outer side of the heat-conducting strips 303 and the outer side of the support filling layer 301 and prevent the outer insulation layer 201 from bulging. A reinforcing groove 304 is formed on the outer side of the heat-conducting strips 303. Reinforcing steel wires 305 are embedded inside the reinforcing grooves 304.

[0032] The working principle and usage process of this utility model are as follows: During the use of the cable, if the cable is exposed to sunlight, the reflective film 207 can reflect the sunlight, reducing the heat absorbed by the cable. The thermally conductive buffer layer 202 is made of thermally conductive silicone. While working with the supporting aluminum wire 205 to support the cable, it can also transfer the heat generated inside the cable to the outer insulation layer 201. The heat is then guided to the thermally conductive buffer layer 202 and the supporting aluminum wire 205 in sequence. When there is wind blowing, the wind passes through the heat dissipation groove 206, which will carry away the heat and cool it down. Reflecting sunlight avoids excessive heat absorption and accelerates heat dissipation. At the same time, it reduces the temperature of the cable to prevent problems caused by excessive cable temperature.

[0033] During cable use, the inner conductor 1 of the cable will generate heat when energized. The generated heat will be transferred to the support filling layer 301 through the support steel wire 209. The heat-conducting strip 303 is made of heat-conducting silicone, which has good heat conduction effect and can accelerate the transfer of heat to the outer insulation layer 201. The reinforcing steel wire 305 in the reinforcing groove 304 increases the strength of the heat-conducting strip 303, further strengthens the cable, and prevents the cable from being broken due to excessive tension.

[0034] The sun-protective support component 2 reflects sunlight to prevent excessive heat absorption while accelerating heat dissipation, functioning on the outside of the cable. Meanwhile, the heat-conducting support component 3 accelerates the heat dissipation from inside the cable, functioning on the inside of the cable. The two components work together to reduce cable heat more effectively.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
