To reduce the safety hazards caused by the wind-induced swing of transmission jump lines and to ensure the safety of power transmission, it is necessary to accurately estimate the dynamic response of the wind-induced swing. The current calculation method for wind-induced swing of jump lines in the Electric Power Engineering Design Manual of High Voltage Transmission Lineignores the pulsation amplification effect of the wind load, and the lines designed based on this method may be unsafe. A finite element coupling model of a high-voltage transmission line was established and the non-linear finite element method was used to calculate the wind-induced swing response of direct and circuitous jump lines. Meanwhile, comparison and analysis were carried out to figure out the shortcomings of the manual calculation method. On this basis, the equivalent static wind load was used to replace the horizontal wind load of the jump lines, and the wind load adjustment factor β_c was introduced to give consideration to the pulsation amplification effect of the wind load for revising the calculation method of the manual. Research results show that the manual calculation method ignored the pulsation amplification effect of wind load, which would seriously underestimate the wind-induced swing response of the jump lines.The maximum error between the manual calculation method result and the finite element result was about 37%, while the wind-induced swing response of the jump line calculated by the correction method was very close to the finite element result. The correction method proposed in this paper can be used to finely estimate the wind-induced swing response of jump lines.
