Exemplary embodiments are directed to a method for producing a circuit-breaker pole part that includes an external insulating sleeve made of a solid synthetic material for supporting and housing a vacuum interrupter insert for electrical switching a medium-voltage circuit. An adhesive material layer at least on the lateral area of the interrupter insert is applied and the coated interrupter is embedded by molding with the solid synthetic material in order to form a single layer of the surrounding external insulating sleeve.
