高温超导导线具有减轻设备重量、减少能量损耗、提高能量密度等优点，在同样直径的情况下，高温超导电缆比一般电缆输电能力提高3—5倍，功率损耗仅为常规电缆的30%至40%。高温超导材料将广泛应用于变压器、电缆、电机等机电设备。　　在欧美等先进工业国家，高温超导材料 High temperature superconducting wire has the advantages of reducing equipment weight, reducing energy loss, increasing energy density, etc. Under the same diameter, high temperature superconducting cable can increase transmission capacity 3-5 times than normal cable and power loss is only 30% To 40%. High temperature superconducting materials will be widely used in transformers, cables, motors and other mechanical and electrical equipment. In Europe and the United States and other advanced industrial countries, high temperature superconducting materials
