In the course of the assembly of a circuit-breaker pole, the individual parts of a housing are stacked loosely one on top of the other and fixedly positioned. This fixing can be accomplished by applying subatmospheric pressure or a partial vacuum within the housing and/or by means of a holding device. Spaces open in the upward direction and located between a fitting and a support insulator as well as between a fitting and a quenching-chamber insulator are then filled with casting material. After this casting material has at least partially hardened, the circuit-breaker pole is turned upside down by rotating the holding device about a horizontal axis, whereupon spaces now open in the upward direction and located between a fitting and the quenching-chamber insulator as well as between a fitting and the support insulator are filled with casting material. This renders possible simple assembly, self-acting mutual alignment of contact pieces as well as a leak test prior to final assembly of the circuit-breaker pole. -2- |
