A Study on the Surface Aging of polymer Insulating Materials Under Salt-Fog Condition

염무 조건에서의 고분자 절연재료의 표면 노화특성에 관한 연구

This paper describes the performance of the widely used polymeric insulating material for outdoor insulation. Various methods to describe the surface aging of polymer materials such as the peak and average of the leakage current, the cumulative charge, the weight loss have been investigated. The relationship between surface current, time are plotted and discussed.
