Study on mechanical properties of the cross arm-insulator system under strong wind load

Abstract High-voltage transmission tower-line systems in coastal areas are often affected by strong winds, which leads to structural damage the towers. Detailed analysis of mechanism towers is very useful ensure safety and stability power system. This paper examines mechanical properties cross-insulator structure under horizontal wind load, then load-carrying capacity deformation performance were analyzed based on ABAQUS. The results show that stable main basically elastic working stage with insignificant flexural torsional effects. On contrary, local stress combined link rod connected insulator large; bending characteristics obvious maximum load can withstand. result provide a reference for cross-arms design.
