![]() ![]() A 220 kV multi-circuit suspension tower with 0°–2° deviation has been considered for present study. ![]() To avoid the use of monopoles and to reduce the base width at the same time, in the present work, an approach has been adopted to use a special lattice type structure with eight legs. But the monopoles are much costlier than the 4-legged lattice towers. In these situations, using monopoles became common practice. Nowadays, in many countries, adequate land is not available to consider such large land occupying towers. The main drawback of a 4-legged lattice tower is its larger base width, which occupy very large area. 4-legged steel lattice tower is one of these structures, which is widely used for this purpose. The main function of these structures is to support the power conductors and earth-wire. For transmission of electricity from power generation plant to substations, many types of structures are being used.
