HIGHLY THERMALLY CONDUCTIVE INSULATING MATERIAL AND SUPERCONDUCTIVE CABLE

摘要

PROBLEM TO BE SOLVED: To provide a highly thermally conductive insulating material having high thermal conductivity at very low temperature and at the same time excellent resistance to low temperature brittleness and a superconductive cable. SOLUTION: This highly thermally conductive insulating material contains resin and >=5 volume % content of a surface treated filler having a high thermal conductivity. The surface treatment of the filler is preferably carried out using a silane coupling agent. This superconductive cable comprises such a highly thermally conductive insulating material as an insulator.
