High-voltage line pin type porcelain insulator and manufacturing method thereof

The invention discloses a high-voltage line pin-type porcelain insulator and a manufacturing method thereof, and relates to the field of pin-type porcelain insulators, the high-voltage line pin-type porcelain insulator comprises a ceramic insulator porcelain column body, the ceramic insulator porcelain column body is of a cylindrical structure, the outer ring of the ceramic insulator porcelain column body is movably connected with a ceramic insulator porcelain outer edge through a connecting assembly, and the outer ring of the ceramic insulator porcelain column body is movably connected with the pin-type porcelain insulator. The second cast steel column body and the ceramic insulator porcelain column body are formed and manufactured in an integral firing mode, so that an installation fixing hole in the inner ring of the ceramic insulator porcelain column body can be fired to be in a fixed shape. And under the supporting effect of the second supporting assembly, the phenomenon of forming failure caused by tigh
