Taking the 220 kV transmission line as the prototype, a test model of the double‐span tower‐line system with a scale ratio of 1 : 20 was proposed on the basis of dynamic similarity theory. 14 different working conditions including zippered, simultaneous, entire, and local ice‐shedding were controlled and realized by use of the program‐controlled mode. The displacement transient responses of transmission line under these ice‐shedding conditions were analyzed in detail. The results show that the variation laws of the ice‐shedding dynamic‐load coefficient and the jump height with the velocity, quantity, and position of the ice‐shedding are obtained, which can provide references for the design of the transmission tower‐line system.
