Optimal MV overhead line arrangement for improvement of the shear-accelerated aging of the H-type concrete power poles

Experiences and evidence show that power poles installed in provinces around Persian Gulf are more exposed to prematured concrete failures. Specifically, severe concrete fractures and cracks occur around the pole anchor due to less elasticity, adding to the porosity and speeding up the attack of the chemical agents. In this study, various factors contributing to the wind-caused shear at the anchor are investigated using Finite Element Method (FEM). On this basis, the most optimal power line arrangement and pole installation are proposed compared to the available standards and procedures in Iran. Using FEM analyzing tools of PLS-Pole and Abaqus, the stress incurred by the wind force is investigated for different available scenarios of Medium Voltage (MV) overhead line designs. Results show that the effects of the conventional power pole implementations and arrangements on pole fatigue have been neglected in design and from this viewpoint, standards in Hormozgan need to be dramatically c
