Mechanic Features

FRAME
All industrial standard alternators is IP21(NEMA1), also IP 23 is an option, But rated power will decrease 5%.
Marine standard alternators is IP23. Air filter is an option, but rated power of the alternator will decrease 5% while it is installed.

AXIS AND KEY
All of the 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 has 12 leads brought out to the terminals in terminal box. The terminal are put on the non drive end. The box is equipped with removable panels.

ENGINE ADAPTOR AND COUPLING
New Era SLG series alternators have two kinds construction.
NEW Era SLG series single-bearing, engine adaptor to SAE00,0,1,2,3,4,5 and 6 coupling discs to SAE6.5,7.5,8,10,11.5,14,18,21 and 24 are available.
New Era SLG series double-bearing, engine adaptor to SAE0,1,2,3,4 and 5 are available.

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 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. This and the 2/3 pitch help to check the wave distortion and output voltage.

Phone interference and Radio interference
THF (defined by 40thpart of BS4999) <2%.TIF<50
Brushless apparatus and quality AVR ensure little radio interference in transmission. RFI noise filter is also available.

Manufacturing Standard
GB755,BS 5000,VDE 0530, NEMA MG1-22,IEC34.

WARRANTY PERIOD
AC alternator arewarranted for 12 months from the notify date of awaiting transportation. Or 1200 running hours (whichever is the shorter period).
