[0002] Power cables are widely used in various fields, including urban construction, industrial production, agricultural production, energy transmission, and emerging technology. Power cables provide stable and reliable power support for modern society, promoting economic and social progress.

[0003] In traditional power cable arrangements, multiple cables are often placed directly in protective tubes without effective separation measures, which can easily lead to mutual entanglement between cables. This not only increases the difficulty of maintenance and replacement, but also affects the heat dissipation effect of the cables. Cables generate a large amount of heat during long-term high-load operation. If the heat dissipation is poor, it may cause overheating, accelerated aging, and even fire hazards. The existing power cable heat dissipation methods usually rely on natural convection or simple fan cooling, which often have low heat dissipation efficiency and cannot meet the heat dissipation needs of high-load operation cables. Some power cables need to be installed in indoor environments, and due to space limitations and poor heat dissipation conditions, the heat dissipation problem of the cables is more prominent.
