Abstract (en)
[origin: US2008078664A1] An insulating material housing has a holding section, which is designed for holding a switching tube and which is fitted with an input connecting piece, and a drive section, which connects to the holding section in a longitudinal direction, has a drive opening for introducing a drive movement into the switching tube, and which is fitted with an output connecting piece. A ventilation shaft is provided that communicates with an inner space of the drive section. The object is to provide an insulating material housing of this general type with which, even in the event of large currents, a sufficiently high cooling capacity is provided. To this end, the ventilation shaft surrounds the holding section in the shape of a collar.
