This study which was presented at the INMR World Congress 2022 in Berlin, by Jan Juhasz, Product Manager of PPC Insulators, is analyzing a replacement of the existing porcelain Long Rod insulator strings with new porcelain Cap & Pin (Disc) insulator strings.
The study and analysis objective was a potential improvement, optimization, and replacement of the existing original OHL Long Rod insulator strings in the selected 5,5km line segment with new Cap & Pin (Disc) insulator strings and new Long Rod insulator strings. The improvement and optimization of existing insulator strings were done based on worsened and more stringent outdoor conditions (environment) than the original OHL design followed by the optimization based on different insulator string lengths, towers dimensions (height, length of arms, foundations), and position and number of towers (suspension type).
