초록

In this paper, aging characteristics of outdoor silicone rubber insulator resulting from the acid rain have been investigated with regards to nitrate ion ($NO_3$). For this purpose, silicone rubber was aged by immersing into the nitric solutions with different level ph during 1500 hours and various tests(tracking, contact angle, $tan{\delta}$, breakdown voltage, SEM, EDS, FT-IR) were performed. It was observed that the degradation was increased to ph 2.5 slightly and highly at ph 1.5. And thus, it could be expected that there is certain critical point between ph 1.5 and 2.5, which leads to throught degradation.
