ANALYSIS AND DESIGN OF 765 KV TRANSMISSION TOWER

Abstract

Considering the continually expanding interest of electricity in the nation, an effort has been made in this work to break down and improve the outline of the tower design. Transmission Line Towers costs upto 30% of the total cost of the transmission line. Therefore, it is imperative for us to economise the design of the tower, thus a cost analysis has also been done compare the effectiveness of the present transmission line for 765 kV. As the idea of high voltage is not new in the nation ,as endeavor has been made in this work to look at the adequacy and expense helpfulness of transmitting the electricity at high voltage to make the transmission line more savvy by changing the geometry (shape) and conduct (sort) of 765 kV transmission line structure. This target of the work is met by selecting a 765 kV single circuit delta configuration transmission line using Square Base Self Supporting Towers. Utilizing STAAD, Analysis of tower has been completed as a three dimensional structure and the same has been designed using the angle sections. The compressive stresses, axial forces , maximum node displacements have been plotted and summarized in graphical manner for the configurations considering the angle and tube sections.
