The utility model relates to a solid-sealed polar pole for outdoor use, which comprises a hollow solid-sealed polar pole substrate, wherein the inner surface of the solid-sealed polar pole substrate is distributed with a layer of silica-gel buffer layer on a vacuum arc extinguish chamber, the outer surface of the solid-sealed polar pole substrate is covered with a protective layer. A dual-layer structure is adopted, the protective layer on the outer layer can adopt materials with strong weather ability, hydrophobicity and pollution flashover resistance ability, and the solid-sealed polar pole on the inner layer can adopt materials with poor weather ability and good toughness, so that different functions are respectively realized by the two layers, not only is the performance of the solid-sealed polar pole greatly improved, but also the dual-layer structure is more cost effective than a single-layer structure.
