LeTourneau AC generators feature three-phase, four-pole design, with lower taps for accessory power and control requirements. Generator windings are dipped in epoxy resin under vacuum pressure to yield a Class H (180 degrees Celsius) insulation. Designed to provide a minimum of 20,000 hours of service life at rated power, they're available in sizes ranging from 400 to 3,000 kilowatts.
