Abstract

Cooling tubes for directly cooled induction winding of electrical machines, esp. turbines generators, running between the rotating winding and the co-rotating coolant feed chamber and drain chamber. The tubes have the required electrical insulating power, are liquid tight, have sufficient pressure resistance and are flexible enough to compensate for heat expansion. They are made in the form of elastically deformable insulating material hoses with a reinforcing coating in the form of a multiply jacket and compression casing on the end of the hose tightly press the hose against the connection nipples.
