Products:Three Phase Generator

Three Phase Generator MWL360-420 Series

The principles of a three phase generator are basically the same as that of a single phase generator, except that there are three equally-spaced windings and three output voltages. We supply different types of three phase generators: Open Diesel generator set, Soundproof Diesel Generator Set, Container Diesel Generator Set and Container Diesel Generator Set to meet your different requirement. If you have any question about our three phase generator, please call or Email us for more information.
