MECHANIC FEATURES

Frame

All industrial standard is IP21,also IP23 is an option.

Axis and Key

All of alternator rotors should pass balance test, whose vibrations are lower than the minimum of BS6861 P.1,G 2.5 two bearing alternator has a half-key testing balance

Terminal and terminal box

The three-field alternator had 12 leads brought out to the terminals in the terminal box. The terminals are put on the non drive end . The box is equipped with removable panels.

Voltage regulation

Voltage regulation refers to the change of voltage from no-load to full-load with power factor ranging from 0.8 to 1 and 3%s fluctuation of the speed of engine. Voltage is adjusted via potentiometer of AVR

ELECTRIC FEATURES

INSULATION

Insulation Class H

All regulatory components are made up with special materials and are immersed in lacquer by peculiar tech. Vanish and colophony materials are develop to strengthen the processing and machinery intensity of windings and revolving parts for protecting the alternator work under corrosive environment.

Winding and electric features:

2/3 pith winding design can effectively eliminate the third harmonic wave(3th.9th,15th) of the voltage ,which is the best design of UPS for nonlinear load .Connected with the network in parallel, the structure can restrain excessive currents in the midline

A continuous damp windings abates surges. The poles and gea
