An embedded pole part is provided with an isolating housing made of thermoplastic material. The housing embeds an interrupter as well as the electric terminals of the pole part. At an outer surface of the housing, horizontal and/or vertical aligned three-dimensional structures joined by material engagement are implemented into the thermoplastic material, to achieve a higher mechanical stiffness as well as higher creepage length of the pole part. The mechanical and dielectric parameters of the pole part are thereby strengthened, for example, in the case of a short circuit current. |
