The cable skeleton 1 is provided with receiving grooves for storing the core 2. The receiving grooves are arranged at equal intervals on the cable skeleton 1. A heat dissipation inner tube 3 is arranged at the center of the cable skeleton 1. A plurality of heat dissipation holes are arranged in the cable skeleton 1 and are in communication with the heat dissipation inner tube 3.

[0032] The heat dissipation holes are in communication with the heat dissipation inner tube 3. The heat generated by the core 2 during operation is transmitted to the air in the heat dissipation inner tube 3 through the cable skeleton 1. The air in the heat dissipation inner tube 3 can flow to the outside through the heat dissipation holes. The heat dissipation holes penetrate the position of the outer skin 6. The heat generated by the core 2 during operation can be transmitted to the position of the outer skin 6 (no heat dissipation holes are arranged in the outer skin 6). The outer skin 6 exchanges heat with the air and materials outside, which can accelerate the evaporation speed of the heat of the core 2 and avoid the temperature of the cable being too high.
