Characterization of Insulation Materials of Oxide Induced Time for Low Voltage Cables with $\tau$-Ray Irradiation

저압케이블용 절연재료의 OIT 특성분석

This study describes the effect of $\tau$ -ray irradiation on the properties of insulation materials for low voltage cables in a nuclear power plant. The radiation effects were characterized by measuring OIT, FTIR, electrical properties of the irradiated specimens. As a result, they showed the decrease of OIT and the increase of chemical structural defects with the increase of $\tau$ -ray amount
