Ultera在美国电力公司（AEP）位于俄亥俄州哥伦布市的Bixby变电站安装了一条200米长的高温超导（HTS）三相三轴设计电缆。该电缆将138/13.2 kV变压器连接到为七个输出电路服务的配电开关柜。它被设计用来携带3000支武器。在AEP三轴电缆的制造和安装之前，在ORNL测试了3至5米长的原型电缆，包括5米的全尺寸终端原型电缆。这些原型机用于演示关键操作条件，包括在3000 Arms设计电流下的稳态运行、高压运行、耐高压和110 kV冲击以及过流故障能力。Ultera和ORNL进行的热分析和测试结果的总结将被提出。本文还对电缆的热液响应进行了分析，并通过试验确定了电缆低温系统的一些要求。
Ultera has installed a single 200-meter long high temperature superconducting (HTS) 3-phase triaxial design cable at the American electric power (AEP) Bixby substation in Columbus, Ohio. The cable connects a 138/13.2 kV transformer to the distribution switchgear serving seven outgoing circuits. It was designed to carry 3000 Arms. Testing of 3- to 5-meter length prototype cables, including a 5-meter prototype with full scale terminations tested at ORNL was conducted prior to the manufacture and installation of the AEP triaxial cable. These prototypes were used to demonstrate the crucial operating conditions including steady state operation at the 3000 Arms design current, high voltage operation, high voltage withstand and 110 kV impulse, and overcurrent fault capability. A summary of the results from the thermal analysis and testing conducted by Ultera and ORNL will be presented. Some analysis of the cable thermal-hydraulic response based on the testing that were used to determine some of the cable cryogenic system requirements are also presented.
