Abstract
In this paper, we studied on life-decision of underground cable of live-line state. Data of CV 6.6kV and 22kV cable's life is got data measured insulation resistance by D.C. overlapped current. We confirmed that D.C resistance reduced by time. Aging of cable could be occurred by electrical, thermal, mechanical stress and complex aging confirmed that proceeded by Weibull plot. In the result, life of 6.6kV cable remained 21 years till light caution and 35 years till heavy caution, so aging of 6.6kV XLPE cable was not occurred. Life of 22kV cable remained 10 years till light caution and 22 years till heavy caution. We confirmed that the designed life of 22kV cable is similar to the measured life.
