Abstract

Series loops of the stator of a large steam turbine-generator are electrically insulated from each other by enclosing each of them in its own clamshell thermoplastic resin mold and filling the mold with an electrically-insulating thermosetting resin material which bonds to the metal of the series loops and the stator bars and bonds also to the ground insulation covering on the stator bars and to the mold and together with the mold provides in cured form an integral body which is resistant to vibrational and impact forces and to distortional forces incident to thermal cycling of the equipement in normal use.
