Ultera/ORNL 团队构建并测试了额定电流分别为 3 kA-rms 和 1.3 kA-rms 的 3 米和 5 米三轴电缆。三个同心超导相由 BSCCO-2223 HTS 带制成，并由冷介电带层隔开。在三个有源相的外部添加铜编织层作为接地屏蔽。这些电缆的测试在 70 至 84 K 的温度范围内进行。交流损耗数据再次证实了之前在 1.5 米原型电缆上的结果，即总三相交流损耗约为三个同心相的计算交流损耗之和。 1.3 和 3 kA 电缆的这些和其他测试结果将用于构造第二条额定电流为 3 kA-rms、15 kV 的 5 米三轴电缆。总结了支持这种新电缆和相关端接的初步测试结果。
The Ultera/ORNL team have built and tested 3-m and 5-m triaxial cables rated at 3 and 1.3 kA-rms, respectively. The three concentric superconducting phases are made of BSCCO-2223 HTS tapes, separated by layers of cold-dielectric tapes. A copper braid is added as the grounding shield on the outside of the three active phases. Tests of these cables were performed at temperatures ranging from 70 to 84 K. AC loss data reconfirmed the previous result on a 1.5-m prototype cable that the total 3-phase ac loss is about the sum of the calculated ac losses of the three concentric phases. These and other test results of the 1.3 and 3 kA cables will be used to construct a second 5-m triaxial cable rated at 3 kA-rms, 15 kV. Preliminary test results supporting this new cable and the associated termination are summarized.
