Abstract
The present invention relates to a reinforced, pressure-resistant flexible tube for mechanical end-winding support for rotating electrical machines. The flexible tube according to the invention in this case comprises a glass fiber bundle which is encased by an inner glass cloth flexible tube. This glass cloth flexible tube is in turn externally coated with a polymer layer and is for its part surrounded by an outer glass cloth flexible tube. A matrix polymer is introduced into the inner glass cloth flexible tube and, after it has cured, the reinforced, pressure-resistant flexible tube can carry out its supporting and spacing function fully.
