Abstract

The insulating bases are provided by pole shells for accommodation of vacuum contactors, with the pole shells each having an enclosure profile which is curved inward and, for detachable connection to the vacuum contactors, each being equipped with vacuum contactor attachment webs which are arranged as mirror images of one another. For detachable connection to the switchgear assemblies, the pole shells are each provided with a pole shell attachment web and, on the inside, have a number of circumferential transverse ribs which run approximately at right angles to the longitudinal axes of the pole shells, and the number of which is matched to the voltage conditions in the vacuum contactors.Pole shells are used for mounting vacuum contactors in switchgear assemblies for electrical power supply and distribution.
