[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 - Figure 2 The utility model provides an embodiment: an aluminum core power cable for network monitoring, including a weather-resistant protective sheath 1, which is made of polyethylene material. The polyethylene material can resist the influence of adverse weather conditions such as ultraviolet radiation, high temperature, low temperature, etc., so that the cable can adapt to various weather conditions when exposed to the outdoors. The weather-resistant protective sheath 1 is used to install a winding core 4 in the middle of the weather-resistant protective sheath 1, and multiple cable cores 8 are installed inside the winding core 4. The winding core 4 is used to fix the multiple cable cores 8 in the winding core 4 through mechanical processing, thereby forming the inner core of the cable. The cable core 8 is made of aluminum. The cost of using aluminum as a conductor material is relatively low. A protective component is provided inside the weather-resistant protective sheath 1, and a barrier component is provided on the periphery of the cable core 8.

[0033] The barrier component includes a semi-conductive buffer layer 7, which is fixedly connected to the outer periphery of the cable core 8. The semi-conductive buffer layer 7 is made of conductive rubber material to reduce local electric field concentration. When the cable is subjected to external mechanical stress or electric field changes, the semi-conductive buffer layer 7 can absorb and disperse stress. The outer periphery of the semi-conductive buffer layer 7 is fixedly connected to an insulating layer 6, which is made of cross-linked polyethylene material and is used to provide high resistance and insulation functions to prevent current from being conducted between the conductor and the external environment, thereby ensuring the safe operation of the cable. The outer periphery of the insulating layer 6 is fixedly connected to a metal shielding layer 5, which is made of copper tape and can block electromagnetic interference, protecting the signal transmission and power supply inside the cable from the influence of external electromagnetic fields. The metal shielding layer 5 abuts against the inside of the winding core 4.

[0034] Reference Figure 1 and Figure 3The protective component includes a waterproof and moisture-proof layer 2, which is fixedly connected to the inner wall of the weather-resistant protective sleeve 1. The waterproof and moisture-proof layer 2 is made of polyvinyl chloride material to prevent water and moisture from entering the cable, avoiding problems such as insulation performance degradation and conductor corrosion caused by moisture. The inner wall of the waterproof and moisture-proof layer 2 is fixedly connected with an anti-wear protective layer 3, which abuts the outer periphery of the winding core 4. The anti-wear protective layer 3 is made of polyamide material. As the first line of defense of the outer layer of the cable, it directly bears external mechanical stresses such as friction, scratches and collisions, and effectively protects the cable from external mechanical damage.

[0035] Working principle: By mechanically installing a weather-resistant protective sheath 1 made of polyethylene on the outer periphery of the winding core 4, it can first ensure that the cable can be used in various environments and can adapt to various weather conditions outdoors. Secondly, the waterproof and moisture-proof layer 2 made of polyvinyl chloride inside the weather-resistant protective sheath 1 can prevent water and moisture from entering the cable, preventing the cable core 8 and the winding core 4 in the cable from being corroded. The wear-resistant protective layer 3 made of polyamide can provide mechanical strength for the weather-resistant protective sheath 1, enabling it to withstand various damages, thereby improving the overall service life of the cable, allowing it to be used for a long time and not easily damaged.

[0036] The cable core 8 is the most important part of the cable. A semi-conductive buffer layer 7 made of conductive rubber is arranged on the periphery of the cable core 8 to disperse the concentrated electric field, reduce the occurrence of electric field concentration, and reduce the risk of insulation damage caused by uneven electric field. The insulating layer 6 made of cross-linked polyethylene on the periphery of the semi-conductive buffer layer 7 can increase the resistance and also has certain heat resistance, which effectively protects the cable core 8. Finally, the metal shielding layer 5 on the periphery of the insulating layer 6 can not only block electromagnetic interference but also play the role of grounding and short-circuit protection. When a cable fault occurs, the fault current will be quickly guided to the ground to reduce the harm of the accident.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
