Abstract: A liquid-cooled armature bar end fitting-to-strand brazed connection. The end fitting is comprised of a main body and a cover, and defines a cavity, a bottom wall of which is defined in part by the cover. An armature winding bar strand package including solid strands and hollow strands arranged in a tiered array extends into the end fitting so that at least the free ends of the hollow strands extend beyond the bottom wall, into the cavity. The side wall of the cavity is spaced from the hollow strands. A braze alloy joins the strands to each other and to the end fitting. The braze alloy forms an isolation layer over the free ends of the solid strands and over the said bottom wall of the cavity to a depth above a horizontal junction between the main body and the cover.

Abstract: A turbine generator with stator windings and a hydrogen pressured stator frame, includes an annular L-shaped collar affixed across a circumference of the stator frame and soldered thereto by a solder joint; a terminal plate anchored to the collar across the circumference of the stator frame and marginally separated from the collar to form a first annulus that contains a first sealant composition that interfaces with the solder bond; and a hardening sealant applied to an upper portion of the solder joint. A high voltage turbine generator is sealed by filling a first annulus formed between an annular L-shaped collar affixed across a circumference of the stator frame and soldered thereto by a solder joint and a terminal plate anchored to the collar across the circumference of the stator frame with a first sealant composition; applying a hardening sealant onto the solder joint; and coextensively covering the first sealant composition and the applied hardening sealant with a second sealant composition.
