Research

The development of high-temperature superconducting cables have been tried around the world and the on-site test was done in actual power system. The electrical insulation system for the high temperature superconducting cable consisted of polypropylene laminated paper (PPLP®) impregnated with liquid nitrogen in many cases, suppressing the problems caused by heat contraction due to the refrigeration. PPLP® is the three-laminated paper formed by extruding polypropylene between two sheets of kraft paper consisted of cellulose fibers. The insulation performance of PPLP® in liquid nitrogen has been reported to be excellent. However, the breakdown mechanism of PPLP® due to its laminated structure has not yet been clarified in detail. So, we have been studying the breakdown mechanism of PPLP in liquid nitrogen for its application to high-temperature superconducting cable.
