Abstract :
A ion migration testing for DC ceramic support insulators was designed and conducted in this paper. After the long-term ion migration testing, the change of Na+ distribution in the tested samples was analyzed, and the mechanical performance of the tested samples was verified. It is indicated from our results that the ion migration testing in our laboratory doesn´t influence the mechanical performance for the ceramic support insulators
