  • Abstract
    We have studied extruded solid polymer insulation for superconducting power transmission cables. Recently, we examined tree initiation properties in polyethylene absorbing helium gas with AC and impulse voltages. As a result, we found that helium gas decreases AC tree initiation voltage. This paper reports the detailed results and discuss the effect of Penning ionization on tree initiation
