FEATURE

- Standard 2/3 pitch windings avoid excessive neutral currents

- Brushless, 4 poles, rotation magnet.

- IP21-23(NEMA1) enclosure is standard for all industrial alternators.

- The insulation system is Class H

- Simple installation and maintenance, with easy access to terminals, rotating diodes.

- Wide range of flange adaptors and single bearing disc coupling.

- Optional accessories available for easy paralleling with mains or other generators.

- AVR auto voltage regulator, auto exciter, auto adjustment.

- All regulatory components are made up with special materials and are immersed in lacquer by vacuum technology, normally used for marine usage standard. Varnish and colophony materials are developed to strengthen the processing and machinery intensity of winding and revolving parts for protecting the generator work under corrosive environment.
