The invention relates to the technical field of cables, and particularly discloses a high-power liquid-cooled cable which is provided with a cooling pipe of a hollow structure, and a conductor layer and an insulating layer which are sequentially arranged on the periphery of the cooling pipe from inside to outside. The pipe wall of the cooling pipe is of a net-shaped structure communicating the internal environment and the external environment. The hollow structure of the cooling pipe forms a cooling channel for leading in and flowing of insulating liquid in a working condition environment, and the insulating liquid flowing in the cooling channel is in direct contact with the conductor layer through meshes in the pipe wall of the cooling pipe to exchange heat. According to the invention, the heat exchange between the insulating liquid and the conductor is rapid and sufficient, the heat dissipation effect is excellent, the light weight and bending flexibility of the formed cable can be greatly improved, and the excellent heat exchange effect can be stably maintained in a complex working condition environment.
