Simulation analysis on structural stability of low wind pressure conductor passing through the pulley

This paper introduces the structure stability of ACSR JL/G1A-630/45-45/7 and low pressure wire DFY-630/45(90 degrees)-R3.2 passing through the pulley under the condition of 25% RTS and envelope angle of 30 degrees. The diameter of the pulley is 20 times the diameter of the wire. Simulation analysis was carried out using finite element software, It is concluded that the structural stability of low-pressure wire is weaker than that of ordinary steel core, but the overall structure is sTable and can meet the engineering requirements.
