Abstract

Transmission towers play a crucial role in the development of modern communities and the expansion of infrastructure projects, especially in developing countries that prioritize power development programs. To ensure the structural integrity and performance of these towers, numerical as well as finite element analysis have been conducted to investigate their load-bearing capacity and failure mechanisms under various loading conditions.
This research work focuses on the optimization of transmission tower design, specifically targeting the reduction of overall weights through the implementation of unconventional grouping systems. Additionally, the study aims to determine the most suitable tower spacing for the entire transmission line, considering various parameters. The towers under investigation are classified as suspension type and are designed to maintain a constant height, common clearances, a consistent span, and standardized conductor and ground wire specifications.
The research follows a systematic approach that involves a comparative analysis between the conventional design practices of transmission towers and the progressively developed investigations. By implementing this sequence of procedures, the study aims to enhance the analysis and design processes of self-supporting 400 KV steel power transmission towers.
The findings of this research will contribute to the optimization of transmission tower designs, resulting in improved structural efficiency and reduced overall weights. By utilizing unconventional grouping systems and identifying the most suitable spacing, the research aims to provide practical solutions that can be implemented in real-world transmission line projects. Ultimately, these enhancement will support the efficient and reliable transmission of electrical power, facilitating the continued development and growth of communities and infrastructure projects
