The invention belongs to the technical field of cable manufacturing, and discloses a charging cable and a preparation method thereof, the charging cable comprises a conductor, an insulating layer, a shielding layer and a sheath layer, the periphery of the conductor is coated with the insulating layer, and leakage of current flowing through the charging cable can be prevented through arrangement of the insulating layer. The shielding layer wraps the periphery of the insulating layer, and the shielding layer is formed by spirally winding the copper strip on the periphery of the insulating layer, so that the copper strip can completely wrap the insulating layer, the conductor and the insulating layer are completely isolated from external electromagnetic interference, the anti-electromagnetic interference performance of the charging cable is improved, and the stability of current transmission of the charging cable is ensured; and the service performance and the service life of the battery are protected. And the sheath layer coats the periphery of the shielding layer, so that the charging cable has friction resistance and extrusion resistance. The charging cable provided by the invention has good external electromagnetic interference resistance, can ensure that the charging current can be stably transmitted when a new energy automobile is charged, and ensures the service life of a battery.
