Effects of UV and Ozone on the Weathershed for Polymer Insulators
폴리머애자 갓 재료에 미치는 자외선 및 오존의 영향
Abstract
The effects of UV and ozone on the weathershed materials for 5 polymer insulators were investigated. This study was carried by material characterizations such as surface microstructure, thermal property, chemical structure and contact angle. The aged specimens are compared with new ones. In case of UV, the chalking of fillers and cracking of surface were increased with the increase of UV radiation time. In case of ozone, aged specimens are not different from new ones. From this study, It can be concluded that UV has more effect on the surface properties of weathershed materials than ozone.
