ADVANTAGES OF MONOPOLE TRANSMISSION TOWER WITH NEW GENERATION CONDUCTORS

Abstract

This paper made an attempt to enlighten the safety parameter of monopole with the Lattice tower transmission line design in urban areas, where required right of way is constraint. Pipe section for monopole and a four-legged section for lattice tower have been chosen as tower profiles. The new generation composite conductors and Steel Reinforced conductors’ properties have been examined for an integral approach. The analysis is carried out with IS 802 (Part-1/Sec-1): 2015 and IS 875(Part3)-2015 revised code versions for 60 m height and 250 m span. It is concluded that the Monopole pipe sections are 6.7% less in weight than the four-legged lattice tower with composite conductors. While comparing the design philosophy of IS 802:2015 code and IS 875-2015 versions, former code contributed an economic design when compared to IS 875-2015 loading procedure. It is further extended that in terms of weight comparison, monopole and four-legged towers have illustrated as 30% & 9.18% less in comparison with IS 875 Code procedure.
