Analysis and experimental testing of a built-up composite cross arm in a transmission line tower for mechanical performance

摘要

This paper discusses the development of a composite cross arm for a power transmission line tower using FRP pultruded profiles. The mechanical performance of the composite cross arm has been evaluated using experimental testing and an analytical solution as well as a finite element simulation. By using the composite cross arm in place of a steel cross arm with ceramic insulators, considerable reduction of transmission corridor is achieved.
