FIELD: electricity.
SUBSTANCE: invention is related to in-built pole part with insulating body made of thermoplastic material with interrupter inserted into it as well as electric terminals as specified in clause 1 of the patent claim. That is why horizontally and/or vertically levelled three-dimensional structures made of thermoplastic material are connected to outer surface of the body in order to reach higher rigidity and length of leakage current pathway in the pole part.
EFFECT: improving mechanical and dielectric parameters of the pole part, especially for short-circuiting case.
