Conventionally for transmission line, lattice towers made of angles are used. For aesthetic reasons and to reduce space at the base, pole structures with polygonal shape, made out of steel plates are used. In this project it is proposed to analyse & design 132KV double circuit transmission pole structures. After designing & analysing the pole structure, the same configuration will be applied on lattice tower, inorder to compare the merits and demerits between lattice & pole. Industry popular PLS-POLE software is proposed to be used. ASCE 48-05 “Design of transmission pole structures” will be used to check the stress limits so as to design plate thickness of various segments of the pole. Base plate design & the connection of pole segments either by slip or flange joint also will be studied in this project. Foundations for transmission monopoles with anchor bolt arrangement or bottom segment inserted in block foundation also will be carried out. Finally limitations of transmission towers usage in terms of distance between poles, plate thickness, grade, plate length availability, fabrication and manufacturing are all will be discussed.
