- Abstract
The present study aims to contribute a better understanding on the aging mechanisms of alumina porcelain long-rod insulators and provides the fundamentals for a life-time-model. Two different approaches are taken: On one hand long-rod insulators are investigated in a tensile test, after their use in high voltage grids, concerning a potential reduction in strength over their lifetime. On the other hand mechanical properties of glazed and unglazed C130 alumina porcelain are determined in a four-point-bending test.
