Abstract

Due to the recent developments of the electric power devices and the HTS power cables, DC superconducting power transmission system is considered to be practical. As one of the R & D issues of the DC superconducting power transmission system, we measured the radiation heat of the thermally-isolated stainless steel pipes with different surfaces. As the result, one sheet of aluminum foil pasted on the inner pipe surface reduced the heat radiation to 1.98 m/W between LN₂ and the room temperature of 300 K.
