Solid sealed pole and production method thereof

The invention relates to a solid sealed pole, which comprises a pouring shell, a vacuum interrupter, a base, an upper connecting terminal and a lower connecting terminal. The upper connecting terminaland the lower connecting terminal are all poured into the pouring shell. The pouring shell is provided internally with a first mounting hole, a second mounting hole and a mounting cavity. The base isscrewed into the second mounting hole by threaded connection. The upper end of the vacuum interrupter is inserted into the first mounting hole. The lower end of the vacuum interrupter is in contact with the base. A wire outlet end of the lower end of the vacuum interrupter passes through the base and extends into the mounting cavity. A production method for the solid sealed pole comprises the steps of placing the upper connecting terminal, the lower connecting terminal and a heat pipe in a forming mold and fixing the same; and injecting a molten plastic into an empty cavity of the forming mold to complete the encapsul
