Suzhou Firstall Electrical Machine & Technology Co.,Ltd.

This is our new design alternators, which are mainly for the frequently starting machine.

The WH series brushless transformers controlled a.c. alternators range from 6.25 kVA to 88 kVA. This robust range of alternators feature superb motor starting capabilities (1 HP per kW). The voltage regulations for this  alternator is + 5 % at 0.8PF.

WHI 16/18 transformer controlled AC generators
- A range of 4-pole, single or two bearing transformer controlled alternators designed for very high motor starting loads (450 % for up to 7 seconds) where fine voltage regulation is less critical
- Engine adaptors to SAE 1, 2, 3, 4, 5 & 6, and coupling discs to SAE 6-1/2, 7-1/2, 8, 10 & 11-1/2
- Windings are specific to output voltage (three phase)
- Voltages available range up to 480 V.
- IP21 enclosure protection standard

The quality of Chinese alternators has improved tremendously. The direct importers who study the market in China and make sure of the origin of their components can source excellent products at competitive prices.

More than 30% by value of all alternators/generators sold in the world are manufactured or assembled in China. Anybody can go onto the internet and find thousands of alternators/generators’ manufacturers all supplying similar products.

Chinese alternators/generators have a similar numbering systems, and even brand names. This confusion comes from the phonetic way in which translation from Mandarin to English is done. You may have two manufacturers with nearly identical names, manufacturing nearly identical products. Quality standards could vary significantly. In summary, the detail easily gets “lost in translation”.

Similarly alternator manufacturers like , Leroy-Somer and Marathon have joint ventures and own plants in China. Their product styles are also widely imitated. Some of these imitations are good, like Firstall brand alternators.

Firstall brushless  alternators are the same design both inside and outside with famous. All of our spare parts can be exchanged with famous alternators. Also, we assure our customers 18 months quality warranty for all the models of our  alternators.

Since our foundation, our company has introduced new and advanced technology and equipment. Moreover, our professionally technical manpower has been devoted to the research and development of new products.

Firstall company is the initial manufacturer, who can make the alternators for marine use except the plant in China. Till now, we have make hundreds of marine use  alternators for domestic and world market.

Another new products: WH series brushless transformers controlled Alternators. It is used for reefer cars, which needs frequently starting. It is range from 6.25 kVA to 88 kVA. This range of alternators features superb motor starting capabilities (1 HP per kW). The voltage regulations for this alternator is + 5 % at 0.8PF.
