Abstract

Cyclic aging for 14days is performed to remove the large amount of the volatiles found in freshly manufactured cable. In this paper, we examined lightning impulse characteristics of power cable before and after cyclic aging for 14days. As the result, the breakdown voltage after aging was lower than that before aging, but the breakdown voltage after aging was higher than that before aging in TR CNCV-W $60mm^2$ power cable.
