Abstract：
 The disclosed method to improve critical current for a Bi-2223 belt material comprises: polishing the insulating varnish on selected area of the material with fine sand paper, cleaning, and using a dc constant power as electroplating source to output 3V voltage and alter plating time for different coating thickness. This invention can control ac loss fit to large-scale production.
