Abstract

The invention relates to a CORC cable with transposed similar layers. The CORC cable comprises a central skeleton and an an even number (>=4) of superconducting tapes; the superconducting tapes are wound on the central framework in a forward and reverse staggered manner, wherein the number of winding layers is m, m is an even number greater than or equal to 2, the winding directions of two adjacent layers are opposite, and the winding angles are symmetrical along the axial direction of the central framework; the first superconducting tape of a first layer is wound on the central skeleton in the forward direction, the first superconducting tape of a second layer is wound on the central skeleton in the reverse direction, a second superconducting tape of the first layer is wound on the central skeleton, a second superconducting tape of the second layer is wound on the central skeleton in the reverse direction, and so on until the winding is completed; every two adjacent odd and even layers are wound in a forward and reverse staggered mode until m layers are wound, and the CORC cable with the transposed adjacent layers is manufactured. According to the invention, the problem of inductance parameter difference between cable layers can be improved, and the uniformity of current distribution is improved.

Description

technical field [0001] The invention relates to a CORC cable with transposition of adjacent layers. Background technique [0002] Compared with several other high-current-carrying high-temperature superconducting conductor cables, CORC cables have high current density, good mechanical properties, and simple manufacturing process in a high-magnetic field environment, and have great development potential in fusion magnet projects. [0003] In conventional CORC cables, each layer is wound separately, and there is no transposition between layers. There are problems such as differences in inductance parameters between layers and uneven current distribution. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcoming of prior art, provide a kind of CORC cable that superconducting strip material transposes winding of adjacent layer, this CORC cable transposes the two-layer strip material of conventional CORC cable and winds alternately, ...
