The technology of compaction of power transmission lines is being increasingly adopted by power industry to effectively make use of the Right of Way (ROW). For technical, aesthetic and economical reasons, our future transmission lines will have to be built with new design concepts using new materials. An attempt was made to build the transmission line tower cross arm with pultruded sections of Fibre Glass Reinforced Plastic (FRP) as a substitute for steel. The metallic towers have been deteriorating and corroding as a result of being in hostile environment i.e., wind, rain and salty environment etc. This paper describes the mechanical behaviour of FRP tower cross arm assembly simulated using Finite Element Analysis (FEA) software and compared with experimental results.

Abstract


The technology of compaction of power transmission lines is being increasingly adopted by power industry to effectively make use of the Right of Way (ROW). For technical, aesthetic and economical reasons, our future transmission lines will have to be built with new design concepts using new materials. An attempt was made to build the transmission line tower cross arm with pultruded sections of Fibre Glass Reinforced Plastic (FRP) as a substitute for steel. The metallic towers have been deteriorating and corroding as a result of being in hostile environment i.e., wind, rain and salty environment etc. This paper describes the mechanical behaviour of FRP tower cross arm assembly simulated using Finite Element Analysis (FEA) software and compared with experimental results.
