The invention provides a liquid-cooling high-power direct-current charging cable with a full-symmetric structure, and relates to the technical field of charging cables. The liquid-cooling high-power direct-current charging cable of the holosymmetric structure comprises an inner liquid-cooling pipe which is located in the center of the cable and used for cooling cables on the outer side of the cable, a plurality of inner-layer conductors are arranged on the outer wall of the inner liquid-cooling pipe, an insulating layer is arranged on the outward side of each inner-layer conductor in a sleeving mode, and outer liquid-cooling pipes are arranged at the four corners of the outer side of each insulating layer and used for cooling the multiple cables. Signal lines are arranged on the left side and the right side of the insulating layer, auxiliary power lines are arranged on the upper side and the lower side of the insulating layer, and a plurality of outer layer conductors are arranged outside the insulating layer and located on the two sides of the auxiliary power lines, the signal lines and the outer liquid cooling pipe. The outer-layer conductor and the inner-layer conductor are made of specific high-strength copper conductors and copper materials with the resistivity smaller than or equal to 0.016900 omega.m as conductor raw materials, and six types of ultra-soft annealed copper wires are used as conductor structures to be stranded, so that the flexibility and high conductivity of the finished cable are guaranteed, and the charging rate is increased.
