Frequently Asked Questions

Table Of Content

1. Do You Offer OEM Service?

Yes, not only OEM but also ODM service.

2. What Is Your MOQ?

MOQ for diesel Genset is 1 set. and for alternators or electric motor is for 10pcs.

3. What Is Your Payment Term?

We accept T/T and L/C at sight.

4. What Is Your Power Range Of Generator?

We provide power range from 3kva to 3000kva.

5. What Are The Voltage And Fre. Of Generators?

50/60Hz, 380/220V, 400/230V, 415/240V, 6000V, 11000V or as customer require.

6. What Is Your Warranty?

The warranty for alternators is 12 months, calculated from the date of notice of the shipment. Or 1200 running hours, based on the shorter.

7. Does Every Product Have A Strict Test Before Ex-Factory?

Absolutely, Every product will be tested twice before ex-factory and our products are 100% ex-factory pass rate.

8. What Is Your Leading Time?

Average 40 days.

9. What’s The STANDARD Of Alternators?

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

10. How To Keep The AXIS AND KEY Stable?

All of the alternator rotors should pass the 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.


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

12. Which Of ENGINE ADAPTOR AND COUPLING In The Alternator?

New Era SLG series alternators have two kinds of 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 refers to the change of voltage from no-load to full-load with power factor ranging from 0.8 to 1 and 3%’ fluctuation of the speed of the engine. Voltage is adjusted via the potentiometer of AVR.

14. What’s Insulation Class H for products?

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

15. What’s 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 the 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.

16. 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.

  1. Hi. I haven’t used my gt generator 3300i for long time; started fine, was charging phone via extension cord fine. Added fridge and then stopped charging, generator kept going, but green AC light is flashing. Cheers Russell
