Technical Field

[0001] The utility model relates to the technical field of power cables, in particular to a high-flexibility and high-shielding power cable. Background Art

[0002] With the continuous development of modern power transmission and distribution systems, the performance requirements for power cables are also increasing. Traditional power cables are no longer able to meet these demands, especially in applications requiring high cable flexibility and shielding, such as industrial automation, rail transit, data centers, and complex wiring environments. These applications require not only excellent conductivity and insulation, but also high flexibility to adapt to various bends and twists, while also being able to effectively resist external electromagnetic interference to ensure stable and secure power transmission.

[0003] However, the structural design of traditional power cables often focuses on improving a single performance, such as focusing only on the conductivity of the conductor or the insulation performance of the insulation layer, while ignoring the flexibility and shielding of the cable as a whole. In addition, when traditional cables are exposed to harsh environments such as humidity and flooding, their insulation layers are easily damaged, which affects the service life and safety of the cables.
