The invention discloses an energy-saving and loss-reduction large-section conductor applicable for an AC submarine cable. The energy-saving and loss-reduction large-section conductor comprises a central round copper wire layer, a first enameled wire isolation layer, a first round copper wire layer, a second enameled wire isolation layer, a second round copper wire layer, a third enameled wire isolation layer and a third round copper wire layer which are arranged in a concentric circle from inside to outside. The large-section cable conductor is partitioned to a plurality of concentric rings with same area by fiber insulation papers, water blocking tapes and the like for an enameled wire and the cable, the skin effect is reduced, the resistance increase is reduced, the running loss of the large-section AC submarine cable can be substantially reduced, the line loss is reduced, the power transmission efficiency is improved, and the energy-saving and loss-reduction large-section conductor has favorable applicatio
