[0018] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described below in combination with drawings and examples.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, as Figs. 1-3 As shown, this utility model provides an energy-saving and low-consumption aluminum core cable that can reduce electromagnetic loss, including a cable body 1, a wire core 2 inside the cable body 1, an insulation layer 3 on the outer wall of the wire core 2, a shielding layer 4 on the outer wall of the insulation layer 3, a buffer layer 6 outside the shielding layer 4, and a sheath layer 9 outside the buffer layer 6.

[0021] The overall effect of Embodiment 1 is as follows: Insulation layer 3 is made of polyimide varnish, which prevents current leakage and also affects electromagnetic loss. Shielding layer 4 is made of copper wire, which provides a good electromagnetic shielding environment for signals inside the cable, reducing energy loss due to electromagnetic induction. Buffer layer 6 is made of thermoplastic elastomer, ensuring stable electromagnetic performance and reducing increased electromagnetic loss due to structural damage. Sheath layer 9 is made of neoprene rubber, which, when intact, ensures normal operation of the cable under various environmental conditions, maintaining the performance stability of each internal layer and thus reducing electromagnetic loss. Through the arrangement of insulation layer 3, shielding layer 4, buffer layer 6, and sheath layer 9, the cable's insulation capacity, anti-interference capacity, buffering capacity, and protection capacity are effectively improved, while electromagnetic loss is reduced.

[0022] Example 2, as Figs. 1-3 As shown, furthermore, an anti-ant and insect layer 7 is fitted onto the outer wall of the buffer layer 6.

[0023] Furthermore, there are four cores 2, four insulation layers 3, and four shielding layers 4. The core 2 is made of aluminum, which is also a commonly used material. Although its conductivity is slightly lower than that of copper, its cost is lower. If high-purity aluminum is used, its resistance can be further reduced, thus reducing electromagnetic losses.

[0024] Furthermore, the insulation layer 3 has a thickness of 0.2mm to 0.5mm, and the shielding layer 4 has a thickness of 0.3mm to 0.6mm. The insulation layer 3 is used to prevent current leakage and also affects electromagnetic loss. The shielding layer 4 is made of copper wire. The copper wire braided shielding layer 4 can provide a good electromagnetic shielding environment for the signals inside the cable, effectively blocking the leakage of the electromagnetic field inside the cable to the outside, preventing external electromagnetic field interference, and reducing energy loss caused by electromagnetic induction.

[0025] Furthermore, a filling layer 5 is provided between the buffer layer 6 and the shielding layer 4. The filling layer 5 is made of glass fiber, which can effectively support the internal structure of the cable, maintain the relative position stability between the conductor and other layers, and prevent performance degradation caused by cable deformation.

[0026] Further, the waterproof layer 8 is arranged between the anti-ant layer 7 and the sheath layer 9.

[0027] The effect achieved by the whole embodiment 2 is that the material of the anti-ant layer 7 is pyrethroid, which can effectively prevent ants from biting the cable, and meets the environmental protection and safety requirements in the use process. The material of the waterproof layer 8 is asphalt, which has good waterproof performance and can form a continuous waterproof layer 8 to prevent water penetration. Through the arrangement of the anti-ant layer 7 and the waterproof layer 8, the anti-ant ability and waterproof performance of the cable are effectively improved.

[0028] Working principle: the material of the core 2 is aluminum, which is a commonly used material. Although the electrical conductivity of aluminum is slightly lower than that of copper, the cost is lower. If high-purity aluminum is used, the resistance can be further reduced, and the electromagnetic loss can be reduced. The material of the insulation layer 3 is polyimide paint. The insulation layer 3 is used to prevent current leakage and also has an effect on electromagnetic loss. The material of the shielding layer 4 is copper wire. The braided shielding layer 4 made of copper wire can provide a good electromagnetic shielding environment for the signals inside the cable, effectively block the leakage of the electromagnetic field inside the cable to the outside, prevent external electromagnetic field interference, and reduce the energy loss caused by electromagnetic induction. The material of the filling layer 5 is glass fiber, which can effectively support the internal structure of the cable, keep the relative position between the conductor and other layers stable, and prevent performance degradation caused by cable deformation. The material of the buffer layer 6 is thermoplastic elastomer, which can prevent damage to other layers caused by external forces (such as bending, stretching, etc.) during manufacturing, installation or operation, indirectly maintain the integrity of each layer, ensure stable electromagnetic performance, and reduce the increase of electromagnetic loss caused by structural damage. The material of the anti-ant layer 7 is pyrethroid, which can effectively prevent ants from biting the cable, and meets the environmental protection and safety requirements in the use process. The material of the waterproof layer 8 is asphalt, which has good waterproof performance and can form a continuous waterproof layer 8 to prevent water penetration. The material of the sheath layer 9 is chloroprene rubber, which protects the internal structure of the cable from external mechanical damage, chemical corrosion and water intrusion. When the sheath layer 9 is intact, it can ensure the normal operation of the cable under various environmental conditions and maintain the stable performance of the internal layers, thereby reducing electromagnetic loss. Through the arrangement of the insulation layer 3, the shielding layer 4, the buffer layer 6, the anti-ant layer 7, the waterproof layer 8 and the sheath layer 9, the insulation ability, anti-interference ability, buffering ability, anti-ant ability, waterproof performance and protection ability of the cable are effectively improved, and the electromagnetic loss is reduced.

[0029] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
