<p>The invention relates to an embedded pole part with an isolating housing (1) made of thermoplastic material, which embedds an interrupter as well as the electric terminals of the pole part, as given by the preamble of claim 1. So it is an object of the invention, to strengthen the mechanical and dielectric parameters of such a pole part especially for the case of short circuit current. Therefore, at the outer surface of the housing horizontal, and/or vertical aligned 3-dimensional structures (3,4,5) joined by material engagement are implemented into the thermoplastic material, in order to achieve a higher mechanical stiffness as well as higher creepage length of the pole part.</p> |
