An Examination on Torsional Loading and Environmental Effect on Glass Fibre Reinforced Polymer Cross Arm in Transmission Line Tower

Abstract

Transmission Line Towers have crossarm which is from Glass-Fibre Reinforced Polymer (GFRP), where the insulator assembly and bare line conductor are located at a safe distance from the tower structure. Crossarm structures normally subjected to various load combination. Therefore this paper will provide a review on the previous researches on GFRP due to the torsional loading and torsional behaviour of GFRP structures, where it was revealed that the mechanical strengths. In addition, the GFRP alone has others advantageous which generally more robust compared to other conventional materials on strength which regard to high strength and stiffness-to-weight ratio, corrosion resistance, chemical stability. It has the capability to sustain various loads, longer serviceability and perform as a good insulator in lightning impulse strength.
