Insulation of large rotating machines in Latin America

The construction of a 42,000 KVA, 28 pole, 13.8 KV hydroelectric generator may be a commonplace occurrence in the factories of the large electrical manufacturers of North America. But it is far from an everyday event in a country such as Brazil. In fact, the machine of this rating now being built in G. E.´s new plant in Campinas should be considered an accomplishment of some magnitude for Americans, since it represents the first large vertical waterwheel generator ever built by an American company in Brazil.
