“…14,15 Hence, some simplified models that take into consideration the coupling characteristics were established for cases of transmission tower and line systems. 16 Bhowmik et al 17,18 have made an effort to analyse the performance of transmission tower of composite, modelled in a standard analytical platform for analysis of stability and strength under different loading conditions considering real life applications. An evaluation was done to reveal the maximum tensile stress in members close to the base of structure to be 210 MPa, whereas the breaking stress (theoretical) of the composite is 1200 MPa which is found to be much higher than tensile stress that occurred at the transmission tower under various load conditions, hence, concluded to be a stable composite tower.…”

The cross-sectional degradation of steel transmission tower members due to corrosion has been one of the major issues in the transmission line system. The degradation of appearance of the material has also been seen because of corrosion. Therefore, there is a need for a less corrosive and high strength alternate material for transmission towers. It seems in recent years that alternate materials have been needed to replace steel which have low maintenance cost and good resistance to corrosion. The advantages of composite transmission towers are fire resistant, high stiffness, durability, high strength, moderate ductility, rigidity, easy to assemble and economical. The present study has made an effort to evaluate the performance of composite transmission tower. The glass fibre polyamide composite material has been used as a structural material. First, a finite element tower model of 132 KV has been set up in Structural Analysis and Design Software as glass fibre polyamide structural material as per transmission tower design guidelines (Code for Transmission tower design, IS 802.1.1.1995, Bureau of Indian Standards). Second, all the active loads like wind load on the body, wind load on conducting wires and ground wires, weight of conducting wires, weight of structure, weight of ground wires, weight of insulator and weight of line man with tools are calculated manually as per transmission tower design guidelines and applied in the finite element tower model. The stress distribution of the composite tower model has been simulated in Structural Analysis and Design Software and the results have been analysed. The broken wire condition (if one conductor is broken or earth wire is broken) has been innovatively considered in the present study. Results obtained in this article show that maximum induced stress on transmission tower member is less than the deign strength of glass fibre polyamide composite material. The glass fibre polyamide composite material has been found to be capable to withstand the maximum stresses induced due to different loading conditions considered in the study.

In case of steel transmission towers, exposure to moisture, humidity, oxygen and other corrosive agents present in the atmosphere can lead to the formation of rust or corrosion on the surface of the steel members. In terrestrial environments, wind and rain may cause moisture to accumulate on the surface of the towers, providing a perfect breeding ground for corrosion. In marine environments, saltwater can accelerate the corrosion process, as dissolved salts can act as a conductor for electrochemical reactions. It causes the loss of material from the surface of the steel members, resulting in a reduction in their cross-sectional area. This reduced cross-sectional area weakens the load carrying capacity of the affected members and can compromise the overall stability of the tower structure. The degradation of appearance of these steel towers can impact both the functionality and visual appeal of the structure. Corroded towers may become weak and prone to collapse, which can endanger the safety of people and the infrastructure around it. Therefore, composite materials have emerged as a promising alternative to traditional material like steel in various applications, including transmission tower construction. The Glass Fibre Polyamide (GFP) composite material has been used instead of steel. In the present work effort is made to study the various literature reviews in order to study the properties of GFP composite material, different composite material used instead of steel for transmission tower. Transmission tower of 220KV has been modelled in STAAD PRO V8i software by considering GFP composite material. As per transmission tower design guidelines (IS 802.1.1.1995 - Code for Transmission tower design), all the loads acting on transmission tower are calculated manually. Analysis of GFP composite transmission tower has been carried out for normal operating condition and broken condition (one power conductor and earth wire is broken).
