Transmission Line Overview


Transmission line towers set up about 28% to 42% of the cost value of the transmission line. In the growing demand for electrical power can be come across more economically by evolving altered light weight patterns of transmission line towers. The choice of an optimal outline organized with right sort of height, bracing system, cross arm type and additional parameters gives to a high range in developing a cost-effective designing of transmission tower. As an objective of each designer are to plan the optimum systems. However, due to the practical limitations this has been attained through intuition, practice and repeated trials. 

Four Legged Tower (Transmission Line Tower)


Transmission line towers are used for associate the Extra High Voltage (EHV) or high current electric transmission line. This is all together given upswing to the need for moderately large supporting structures. The planning engineer is delegated with the exciting job of design and erecting transmission structures to backing substantial conductor loads in exposed weather conditions with large temperature of consistency and protection to the common public make certain pleasing serviceability.

Three Legged Tower


In general 4 legged lattice towers are furthermost usually used as a transmission line towers. 3 legged towers only used as radio, microwaves, guyed towers and telecommunication but not used in energy field as a transmission tower line. The patterns of 3 legged transmission towers are very tough because of cross arm and backing arrangement not effortlessly and perfectly probable. The axial force and deflection are raised in 3 legged tower modules as compared to 4 legged tower modules but convertible in steel weightiness of 21.2% bring about when we using a 3 legged tower as linked with a 4 legged towers.
