Abstract
A construction is provided for the stator coil ends of large dynamoelectric machines such as turbine generators of the inner-cooled type which effectively insulates the ends of the gas coils and mechanically reinforces them without interfering with ventilation. An insulating vent cap is applied over the ventilating tubes at each end of each conductor. The vent caps have a soft, uncured portion and are fitted to the conductor and then impregnated with a resin and cured in place to obtain a good fit of the cap on the conductor. The complete coil ends and connections are then covered with an insulating and mechanically reinforcing tape.
