Description

Technical Field

[0001] This application relates to the technical field of overhead line snow removal, and particularly to a snow removal device for overhead transmission lines. Background Art

[0002] Transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines are composed of line towers, conductors, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., which are used to erect the transmission lines high in the air. In cold winters, the tension of the transmission lines becomes larger. When encountering heavy snow weather, the overhead transmission lines in the wild are extremely likely to accumulate snow, which further increases the line tension. If the accumulated snow covering the lines is not removed in time, and more snow accumulates after the snow freezes, it is very easy to cause the lines to be broken by the pressure, resulting in a large-scale power outage.
