Abstract

Southwire Company has installed the world's first industrial high-temperature superconducting cable system to power three of its main manufacturing plants. The cable consists of three single-phase, 30 m long cables designed to carry 1250 A at 12.4 kV. The cable is cooled by a liquid nitrogen (LN) system that can supply LN at sub-cooled temperatures down to 72 K and at pressures up to 15 atmospheres. The design of the 30 m cables is based upon two 5 m cable prototypes, which were tested at a specially developed facility at ORNL. In addition to critical current and AC loss measurements, simulated fault-current tests were performed at ORNL on the 5 m cables. Cable terminations were designed to allow smooth transition from the cryogenic temperature and pressure environment of the HTS cable to ambient temperature and pressure for copper cables. A dielectric tape material, Cryoflex/sup TM/ was also developed for use at cryogenic temperatures.

世界上第一条工业用高温超导电力电缆的研制与试验

南线公司安装了世界上第一个工业高温超导电缆系统，为其三个主要制造工厂供电。该电缆由三根单相，30米长的电缆组成，设计用于承载12.4 kV的1250 A。该电缆由液氮(LN)系统冷却，该系统可以在低至72k的过冷温度和高达15个大气压的压力下提供液氮。30米电缆的设计是基于两个5米电缆的原型，它们在ORNL的一个专门开发的设施中进行了测试。除了临界电流和交流损耗测量外，还在ORNL对5米电缆进行了模拟故障电流测试。电缆终端的设计允许从高温超导电缆的低温和高压环境平稳过渡到铜电缆的常温和高压环境。还开发了一种用于低温的介电带材料Cryoflex/sup TM/。
