1)Any permanent magnetic generators, providing invariable
excitation on all occasions.
2)Easy to be connected with power network or other generators.
Standard 2/3 pitch windings check excessive midline current.
3)Balanced rotor with single or two sealed ball bearings
4)Convenient installation and maintenance with easy access to
terminals, rotating diodes and coupling bolts
5)Wide range of Flange adaptor and single bearing coupling disc
Meet leading standards
All industrial standard is IP21,also IP23 is an option, but rates
power will decrease 5%
Marine standard alternator is IP23,Air filter is an option, but
rated power of the alternator will decrease 5% while it is
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 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
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 gears of
the windings are carefully chosen, this and the 2/3 pitch help to
check the wave distortion and output voltage.
THF(defined by 40thpart of BS4999) <2%.TIF(defined by
Brushless apparatus and quality AVR ensure little radio
interference in transmission. RFI noise filter is also available.

Factory Inspection, the test items before delivery are mainly as
1. Each genset shall be put into commission more than 4 hours
They are tested on idle load, fully load and 10% overload
2. The noise level is tested
3. All of the meters on the control panel shall be tested
4. The appearance of the genset and all of the label and nameplate
shall be checked
