Porcelain Long Rod versus Cap & Pin Insulators: Impact on Overhead Line Design

A study was completed with the goal of improving performance of a segment of existing 400 kV OHL using new cap & pin insulator strings and new long rod strings given worsened service conditions than in the original design. Different string lengths, towers dimensions and position and number of towers were analyzed, respecting insulation coordination and all other constraints. This presentation covers findings and shows how efficiency of overhead systems can be increased and optimized based on a new tailored porcelain long rod insulator design and professional design tool.
