Special attention should be paid regarding strength and stability of the transmission tower structure which are made with composite materials. In this present study, an effort has been made to analyze the strength and stability of transmission tower made with composite material, Carbon Fiber Epoxy (CFE). The transmission tower is modeled in STAAD considering CFE as structural material to analyze it in terms of strength and stability with different loading conditions in real life application. The maximum tensile stress is found at the transmission tower members near to the base of the structure with the amount of 210MPa. The breaking stress of CFE material is 1200MPa which is much more than the tensile stress occurs at the transmission tower at different loading conditions. The innovative design approach incorporating stability analysis found to be most competent for stating the stability and strength of tower and further clarify the safety approach of design.

The American Society of Civil Engineers (ASCE) assigns a grade of “D+” to the grid infrastructure and ranked its aging and condition the Number One challenge to reliability, both in likelihood of occurrence and potential severity. An unreliable electric grid will have significant negative impact both from an economic and security aspect. The direct cost to the grid from corrosion alone is some $700 million annually with indirect costs much higher.
