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.8 cl, 4 dwg |
