Chapter 3.8: DC Cable for Data Center
The internet data center (iDC) is becoming one of the most important and widespread infrastructures in modern life, but it consumes electrical power plentifully. The reduction of its electric power consumption is an urgent subject. A Direct current (DC) power systems are now being applied. The DC high temperature superconducting (HTS) power cable is well-suited for such systems and is a suitable application in applied superconductivity. Subjects of the superconducting power cable system are discussed, especially about the cable design and the heat leakage of the current lead. Several ideas are proposed and discussed for the future iDC using HTS power cable and renewable energy (RE) system.
