This invention discloses a porcelain insulator with a snow and ice removal structure and its manufacturing method, relating to the field of insulators. It includes a lower insulating column, an upper insulator, a snow removal assembly, and a central connecting bolt. By setting an upper insulator with a size larger than the lower insulating column's skirt, it can effectively block the lower insulating structure, confining most of the snow accumulation to the surface of the upper insulator. Furthermore, the icicles formed at the edges of the upper insulator are difficult to connect with the snow and ice on the lower insulating column. Through a sliding connecting seat cooperating with the central connecting bolt fixed to the crossarm, the swaying kinetic energy of the transmission line is converted into the up-and-down sliding of the snow removal assembly relative to the upper insulator. This sliding motion drives multiple vibrating plates to periodically squeeze and scrape the surface of the upper insulator, causing the accumulated snow and ice to loosen, break, and slide off. This allows for timely de-icing without additional energy or manual intervention.
