5. Common FAQ

5.1 What is the actual usage difference between prime power and standby power of 6ZTAA13-G2 generator set?

The 340kW/425kVA prime power is the rated continuous power of the unit, supporting 24-hour long-term uninterrupted operation and allowing short-term 10% overload operation, which is specially designed for off-grid main power supply and long-term continuous power generation scenarios. The 380kW/475kVA standby power belongs to emergency peak power, only applicable to short-time power supply when municipal grid fails. It cannot operate continuously for a long time, otherwise it will cause excessive engine load, accelerate wear of internal parts, and greatly shorten the overall service life of the generator set. In actual use, users need to select the power mode according to daily operation demands to avoid long-term overload operation.

5.2 What core advantages does Cummins 6ZTAA13-G2 generator set have in power stability?

This unit adopts Dongfeng Cummins 6ZTAA13-G2 professional generator drive engine, matched with GAC electronic governor and AVR automatic voltage regulation system. The electronic governor can accurately control speed fluctuation within a small range and intelligently adjust fuel supply with load changes. The turbocharged intercooled intake structure ensures sufficient and stable power output. Even in the state of sudden load increase or mixed load operation, the voltage and frequency can remain stable without obvious fluctuation, which can well protect precision electrical equipment and industrial production lines from power quality problems.

5.3 What harsh working environments can IP23 protection grade and H-grade insulation adapt to?

The IP23 protection grade can effectively block large solid dust particles and prevent splashing water from all directions, which can adapt to open-air construction sites, dusty mining areas, humid coastal environments and semi-outdoor workshop power supply scenarios. The H-grade high-temperature resistant insulation is a high-standard generator insulation material, which can maintain stable insulation performance in the temperature range of -20℃ to +45℃, and will not have insulation aging, breakdown and short-circuit faults after long-term high-load and high-temperature operation. The dual high-standard configuration greatly improves the environmental tolerance of the unit and ensures stable and fault-free operation in various complex working conditions.
