　 Counter flow cooling is one of effective cooling systems for superconducting power cables. In designing of HTc superconducting power cables, investigating cooling characteristics of the liquid nitrogen counter flow are important. We conducted cooling test of 100m-long duplex-counter-flow tube. In the paper, longitudinal temperature distribution in the tube and initial cooling characteristics are described. An analytical model to calculate the temperature distribution of the tube is also mentioned.
