The invention discloses a preparation method of a low-cost high-strength Bi-system superconducting wire strip. The method comprises the following steps: 1, scrubbing the surface of the Bi-system superconducting wire strip to remove residual dirt; 2, performing electrochemical polishing on the scrubbed Bi system superconducting wire strip to remove an Ag alloy layer; 3, cleaning residual liquid; and 4, performing surface enhancement treatment on the cleaned Bi system superconducting wire strip to form a Cu layer, thereby obtaining the low-Ag-content high-strength Bi system superconducting wire strip. According to the method, an electrochemical polishing method and an electrochemical material adding method are combined, the Ag alloy layer on the surface of the Bi-system superconducting wire strip is removed, the high-strength Cu layer is plated, preparation of the low-cost and high-strength Bi-system superconducting wire strip is achieved, the preparation cost is reduced, the strength of ...
