VGP series includes 164/184/224/274/314/354/404/454 total 8 frames, from 5kW(6.25kVA)  to 2240kw(2800kVA). The technical performance and mounting dimension of VGP series alternators are international IEC 34-1 and national GB755 standards compliant, the quality of product can reach current international standard.


VGP Series three-phase (or single-phase)  brushless synchronous, by introducing and developing on foreign advanced technology of well-known generators, are our newly developed products, all data updated synchronously with international well-known generators. VGP series generators can be manufactured in both doubleand single bearing versions with a range of easy coupling to internal andinternational engines. Its body is constructed by steel shell,  stator core is made of whole disc and rotor core is made as whole salient pole type with full-damping,with brushless self-exciting method and AVR automatic control. It has following features: small-size, light-weight, good appearance, perfect performance, and easy access for installation and maintenance.

VPG series alternators meet the quality standard of internationalwell-known generators, we guarantee the quality by strictly-controlled producedesign, manufacturing technology, tooling, selection of raw materials,production, testing equipment and quality control. Selection of raw materialsincludes cold rolled silicon sheet and magnet wire, which are purchased fromthe best of internal supplier, producing and test equipment such as coil windercan effectively control the magnet wire’s pulling force while winding, toolingsuch as stator laminated tooling is very advanced and it can ensure the statorcore’s quality, manufacturing technology such as VPI and wet-winding technologycan ensure that the windings have the high level of protection. All of qualitycontrol including field control is carried out according to ISO9001 standard.

1.   Excellent compatibility with drive systems: standard mounting dimensions can be coupled to any diesel engines from would wide, many S.A.E flanges and S.A.E drive can be easily interchangeable.
2.    Good environmentally-friendly protection system: the standard enclosure protection is IP23, insulation classis H, and VGP alternators made with advanced manufacturing technologies are suitable for harsh environments.
3.    Reliable and powerful automatic voltage regulators can provide consistent excitation on all occasions, so the alternators can run reliably, and have high performance of magnet on exciter stator which can rapidly build voltage while starting; all AVR’s have numerous features for voltage adjustment, stability adjustment, low frequency protection and exterior voltage adjustment.
Standard AVR: SX460;
Option AVR: AX440/SX440/KR440... (can be suitable for operation in parallel), MX341 is suited for auxiliary windings, thus providing the alternator with the best design for nonlinear load, performance on start and short-circuit.
4.    VGP alternators are provide with a 2/3 winding pitch as standard, therefore are perfectly suitable for in stallations with distorting loads, and easy to be operated with other alternators in parallel; several types of windings are available in 50Hz and 60Hz versions to optimize performance according to voltage required on site and the demands of application (max. volatages available range up to 690V).
5.    VGP alternators are provide with three phase as standard, it’s easy to alter the voltage by reconnection for 12-leads on terminal plate, also the units can be run as single phase by changing the output connecting (except for VGP354/404/454 series), but single-phase’s power is about 58% of the three-phase’s; for single phase generator, it can be designed for special winding.
6.    The damp winding on rotor and the surge suppressor on rectifier can provide the alternator with stability and reliability.
7.    For balanced rotor with two sealed and quality ball bearing, VGP alternator have the features of little vibration and low noise.
8.    Easy access for installation and maintenance, including: coupling to engines, connecting for lead wire, adjustment for AVR, connecting for rectifier, integrating with current transformers

1. Interchangeable S.A.E flanges and S.A.E drive discs
2. Convenient filters on air inlets and outlets
3. Protection for windings in harsh environments
4. Different AVR type
5. Different windings
6. Exterior potentiometer
7. Space heaters
8. Stator thermal protection
9. PMG or auxiliary windings
10. Droop current transformers (C.T.)
