The authors have proved that ethylene-propylene rubber (EPR) is suitable for the solid electrical insulating material of superconducting and cryoresistive cables due to its excellent mechanical and good electrical properties. It is imperative to study the treeing resistivity of EPR in view of long term reliability as a cable insulator.<br>The objectives of this paper are to establish an AC treeing test method of opaque EPR samples with fillers and to examine the treeing resistivity of EPR at both liquid nitrogen and room temperatures and the effect of fillers on treeing resistivity. It was found that EPR has enough resistance to AC treeing at liquid nitrogen temperature and that fillers improve AC treeing resistivity slightly. High reliability of EPR insulation is expected during the long term operation at cryogenic temperature.
