摘要：

We present results on DC current carrying capability and AC transport current losses of cabled conductors assembled from multifilamentary (PbBi)(2)Sr2Ca2Cu3O10+x tapes. The DC critical current of cabled conductors lies systematically below the sum of critical currents of the tapes. By considering the self field a model for the critical current of cabled conductors is derived which reproduces also the dependence of critical currents on external magnetic fields. For the AC self field transport current losses an empirical description based on the Norris model is derived leading to a scaling of the normalised loss. (C) 2003 Elsevier B.V. All rights reserved.
