Abstract

The superconducting transmission cable is one of interesting part in HTS power application using high temperature superconducting tape. One important parameter in HTSC cable design is a transport current sharing because it is related with a current transmission capacity and a loss. The current sharing is decided by cable length (inductance) and resistance (by joint and AC losses). The AC loss in power transmission cable is studied only transport current loss. But, although it is applied no external field, any tapes constituting transmission cable are experienced magnetic fields given by currents flowing in other tapes of cable. In this paper, the authors calculate current sharing for each layer of a 4-layer cable. The transport current loss and magnetization loss for various cable length considering the twist of each layer are also studied
