摘要
The invention pertains to an air-insulated middle voltage switching station, comprising a number of feedthrough post insulators (FPI) provided with busbar connections (BBC), which number corresponds to the number of phases, whereby said feedthrough post insulators (FPI) are removably connected to a post insulator supporting sheet (PISS). The inventive feedthrough post insulators (FPI) have a square outer edges(SOE) connected to square inner edges (SIE) between which clamping slots with concentric transverse edges (CTE) are provided. In the bearing area relative to the post insulator supporting sheets (PISS), the post insulators inner edges (PISE) contains post insulator guiding edges (PIGE), which go across cavities in the post insulator supporting sheets (PISS) and grows smaller into a trapezoid in the direction of the free area, with longitudinal surfaces (SL) facing the post insulator outer edges (PIOE).
