AC Breakdown Characteristics for 22.9kV CV Power Cable Before and After Cyclic Aging for 14days
22.9kV CV 전력케이블의 14주기 고온 열화에 대한 교류파괴특성
Abstract
22.9 kV CV power cable is very important factor of underground distribution power line. Cyclic aging for 14days is performed to remove a large amount of the volatiles found in freshly manufactured cable. In this paper, we examined AC breakdown characteristics of CV power cable before and after cyclic aging for 14days. As the result, even if there were some exceptions, the AC breakdown voltage before aging was lower than that after aging, but most of the results were that the AC breakdown voltage after aging was lower than that before aging.
