【 摘 要 】

This paper describes meteorological condition under extreme cold condition in Arctic. Because icing is an important condition for galloping of the conductor, icing condition of the conductor under extreme cold condition in Arctic is analyzed, influence of temperature about icing of the conductor is obtained. Elasticity modulus of the conductor under low temperature condition is derived by the formula, the calculation model of galloping value of the conductor is established, and carry out simulate calculation and analysis about galloping amplitude and dynamic tension of the conductor, and galloping characteristic of the conductor under extreme cold condition in Arctic is obtained. The calculation results in this paper will provide some reference for design of the conductor under extreme cold condition.
