Technical Parameters of 550KW Diesel Generator Set

The 550KW diesel generator set supplied by Dingbo Power can be produced and tested strictly in accordance with the international quality standard ISO8528 (national standard GB2820-97) for diesel engines. All generator products have passed ISO9001 international quality system certification.

Many users have requirements for the rated power, steady-state voltage adjustment frequency, excitation mode, speed regulation mode, engine speed, starting system, filtration system, smoke exhaust system, speed regulation system, diesel specification level, generator efficiency, insulation level, protection level, excitation mode, etc. when purchasing a 550KW diesel generator set. So, what are the technical parameters and performance indicators? Can diesel generator manufacturers meet these requirements? This article is explained in detail by a professional diesel generator manufacturer.

The above are the general requirements for the configuration and performance of 550KW diesel generator sets. Some customers also have requirements for generator brands, such as 550KW Yuchai generator set, 550KW Shangchai generator set, and 550KW passive generator set. Different brands of generator sets have slight differences in structure, such as some brands have larger or smaller volumes, some brands have heavier or lighter generator sets, and some consume more fuel in terms of emissions, some energy-saving and fuel-efficient factors are the determining factors that affect the user's choice of generator sets.

Dingbo Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
