摘要

研究了超导输电电缆用挤压型固体聚合物绝缘材料。最近，我们研究了聚乙烯在交流电压和冲击电压下吸收氦气的起始特性。结果表明，氦气降低了交流树起始电压。本文报道了详细的研究结果，并讨论了彭宁电离对树形形成的影响。

Tree initiation in polyethylene absorbing helium gas

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.
