This article describes the structure of a device to prevent the formation of ice on the cables of power lines using the impulse shock method with the lateral type of fastening. The actuator of the device is a magnetic pulse electromechanical energy converter. It can ensure that the parameters of the impact match the calculated values in a wide range of times and forces. This advantage determined the choice in favor of this type of actuators. The basic functions of the device are described herein. Based on this, the functional blocks are highlighted and their description is given. The influence of various design parameters of device parts on its performance is described. We also formulated requirements for structural elements. As a result, a reasonable choice was made when designing the device. A laboratory unit was developed to prevent the formation of ice using a scaled-down model of a power transmission line cable. A system for measuring vibrations at several points of a cable is described. The results of an experimental study of wire vibrations are presented. The correspondence of the calculated and experimental values of the cable deviation is shown, which indirectly confirms the correspondence of the developed device’s parameters to the calculated values.
