Abstract
Temperature rise in a quenching cable-in-conduit conductor is strongly affected by thermal contact conductance between the cable and conduit. To evaluate this temperature rise, contact conductance is directly measured under compressive pressure at room temperature by using a small copper bock with heaters. The results show that the contact conductance is affected by surface pressure and the conductivity of ambient gas. Therefore, to evaluate temperature rise in a quenching conductor, it is necessary to take into account conductance under a surface pressure equivalent to an electromagnetic force. In addition, the conductivity of ambient gas must be considered when a surface pressure is low.
