Abstract
An arm assembly is provided. The arm assembly includes a heat exchanger assembly, a plurality of electrical components thermally coupled to the heat exchanger assembly, and a number of electrical buses. Each electrical component is coupled to, and in electrical communication with, one electrical bus. A sealing compound is then applied to each electrical bus and to a limited number of the electrical components.
