Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to a composite cable. Background Art

[0002] A composite cable is a cable composed of multiple different types of cables. It is usually formed by combining two or more cables with different functions or characteristics, and includes multiple types of cables such as power cables, communication cables and control cables.

[0003] After searching, the patent number is CN215681765U, and the name is a utility model of a composite cable, which includes two sets of protective covers and a wire core installed inside the protective covers. Through research and analysis, it is found that although it is convenient for cable connection and prevents leakage at the cable connection, it still has the following disadvantages to a certain extent.

[0004] For example, if the component installs multiple bundles of cables in a centralized manner, the heat generated will be greatly increased. Although the fully enclosed method ensures the sealing of the installation and avoids leakage, it will also greatly affect the heat dissipation performance. The heat accumulated at the joints will not only affect the transmission rate but also easily cause overheating damage to the components, and even overheating and flammability. There are certain limitations. In order to solve the above technical problems, we have designed a composite cable. Utility Model Content

[0013] Preferably, the reinforcement sleeve and the mounting sleeve are connected at a point through threads, and a receiving groove is provided inside the reinforcement sleeve.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:
