[0002] Cable is a device for transmitting electric energy or signals. They are composed of single or multiple wires and an insulation layer and are used to connect circuits, electrical appliances, etc. Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supplies for industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. The outer sheath of existing cables is directly extruded and wrapped around the outside of the core. As the cable is used, the outer sheath structure will separate from the internal core structure. During use, the internal core will rotate and twist, and the core will easily break due to torsional force, affecting safety of use. Utility Model Content

[0016] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0017] Example: See Figure 1-2 The utility model provides a technical solution: a new cable conductor structure. This solution takes into account that the outer protective structure of the existing cable is separated from the core structure due to twisting during use, and the internal core is twisted under force for a long time, which may cause the core to break, affecting the use of the cable. Based on the above content, this case sets the following technical means;

[0018] Specifically, the device comprises at least a plurality of cable cores 1, an inner sheath 2, a shielding layer 3, a pair of positioning frames 4, a wrapping layer 5 and an outer sheath 6;

[0019] A plurality of cable cores 1 are twisted together to form a main structure of the cable core for power transmission. The inner sheath 2 provides mechanical protection to prevent the cable core 1 from being damaged by external forces such as pressure and tension during installation and use. The shielding layer 3 can effectively prevent external electromagnetic interference such as radio frequency and interference generated by power equipment from entering the cable, thereby ensuring the stability and reliability of the cable transmission signal. At the same time, the shielding layer can reduce the impact of the electromagnetic field generated when the current is transmitted in the cable on the surrounding environment, especially the interference to sensitive equipment and electronic equipment. The wrapping winding layer 5 can increase the overall wrapping strength of the cable and fix the positioning frame 4. When the outer sheath 6 is extruded and wrapped, the rod-shaped structure of the positioning frame 4 will be embedded in the outer sheath 6, increasing the anchoring force between the outer sheath 6 and the internal core, effectively preventing separation and falling off during use, thereby ensuring the safety of the cable.

[0020] More specifically, the inner sheath 2 is wrapped and covered on the outside of several cable cores 1, the shielding layer 3 is wrapped and covered on the outer wall of the inner sheath 2, a pair of positioning frames 4 are placed on both sides of the outer wall of the shielding layer 3, a pair of positioning frames 4 are fixed to the outside of the shielding layer 3 by wrapping the winding layer 5, and the outer sheath 6 is fixed on the outer wall of the wrapping winding layer 5.

[0021] In the specific implementation process, further, fillers 7 are arranged on the outside of several cable cores 1 .

[0022] In the specific implementation process, further, a shielding insulation layer 8 is installed on the outer wall surface of several cable cores 1.

[0023] In the specific implementation process, further, a pair of positioning frames 4 are embedded in the outer protective layer 6 .

[0024] In the specific implementation process, further, shielding copper wires are arranged in the shielding layer 3 and the shielding insulation layer 8 .

[0025] In the specific implementation process, further, the pair of positioning frames 4 are semicircular arc structures.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
