As the core product of Langfang Haigong machinery and equipment co., LTD., HGFD series diesel generator sets are widely used in construction, communication, finance, mineral deposit development, leasing and other special occasions due to their excellent performance. As you can expect, HGFD generator sets take to its safe and more reliable features, as well as the personalized design concept to meet your needs, to provide users with excellent performance of professional generator sets: and with its low noise, energy saving, stable performance, to provide a reliable
guarantee for the development of many enterprises.
HGFD diesel generator sets according to the different levels of power, combined with various brands of diesel engines in a specifc power range of performance advantages, the selected engine has flow performance, and special attention to the selected engine in reducing exhaust emissions, reducing fuel consumption and noise control technology advanced.

Generator
The main generators of HGFD diesel generator sets are single-bearing self-service alternators , which have the performance of international famous brands.The main complete set of Marathon alternator, for example, has the following characteristics:
1. Quadrupole brushless self-excited type.Single bearing, H class insulation, IP*2 protection class.
2. The stator is 2/3 pitch wound, which can effectively eliminate the third harmonic of the voltage and suppress the waveform distortion of the output voltage;When connected in parallel with power grid or other generators, it can effectively restrain excessive Central Line current and reduce magnetic feld heating.
3. After dynamic balance test before rotor assembly, perfect damper windings help reduce voltage flattening and heat under unsteady load.
4. The output power of the exciter rotor transport the power to the host rotor through a three-phase full-wave bridge rectifier, which is protected by a surge suppressor to avoid damage caused by shocks such as short circuit or out-of-step phase when the exciter is combined.
5. The automatic voltage regulator (AVR) has the automatic load reduction characteristic of protecting the engine, allowing the full load to be applied to the generator at one time.Stable voltage adjustment rate can achieve plus or minus 1% (special requirements can meet 0.5%).If the permanent magnet generator excitation (PMG) system is selected, the generator will have a higher starting capacity of the motor.
