摘要：Transmission line is an integrated system consisting of conductor subsystem, ground wire subsystemand one subsystem for each category of support structure. Mechanical supports of transmission line represent asignificant portion of the capital cost of the line and they play an important role in the reliable power transmission. Thecost of towers constitutes about quarter to half of the cost of transmission line and hence optimum tower design willbring in substantial savings. They are designed and constructed in a wide variety of shapes, types, sizes, configurationsand materials.The types of supporting structure generally fall into one of the three categories: lattice, pole and guyed. Thesupports of EHV transmission lines are normally steel lattice towers. The selection of an optimum outline togetherwith right type of bracing system contributes to a large extent in developing an economical design of transmissionline tower. The height of tower is fixed by the user and the structural designer has the task of designing the generalconfiguration, members and joint details.The goal of every designer is to design the best (optimum) systems. But, because of the practical restrictions thishas been achieved through intuition, experience and repeated trials, a process that has worked well.In this paper, analysis and design of a specific angle /tension type double circuit tower with economical sections for110KV transmission line with 9m extension to have adequate vertical clearance between center line of railwaytrack and bottom most conductor of the transmission line is made.
