However, during the use of the high-voltage wires and cables in the above document, due to the lack of anti-static structure inside the high-voltage wires and cables in the above document, the high-voltage wires and cables in the above document are in the process of power transmission. The high-voltage wires and cables are all in contact with the insulating material, which easily leads to the accumulation of static electricity inside the high-voltage wires and cables, resulting in poor current flow stability during the power transmission process of the high-voltage wires and cables;

[0008] Preferably, the inner wall of the antistatic component is filled with a filling structure.

[0009] Preferably, the outer wall of the antistatic component is bonded to the supporting component.
