5. Common FAQ

5.1 What is the practical usage difference between prime power and standby power of 6ZTAA13-G4 generator set?

The 350kW/438kVA 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 moving parts, and greatly shorten the overall service life of the diesel generator set. Users need to match the power mode according to actual working conditions to avoid long-term overload operation.

5.2 What are the core advantages of Cummins 6ZTAA13-G4 generator set in power stability?

This unit adopts Dongfeng Cummins 6ZTAA13-G4 dedicated generator engine, matched with GAC electronic governor and AVR automatic voltage regulation system. The electronic governor can precisely control engine speed fluctuation and intelligently adjust fuel supply according to real-time load changes. The turbocharged air-air intercooled intake structure ensures sufficient and stable power output. Even under mixed load operation or sudden load increase conditions, the unit can maintain stable voltage and frequency without obvious fluctuation, effectively protecting precision electrical equipment and automated production lines from power quality damage.

5.3 What 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, adapting 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℃. It will not experience insulation aging, breakdown or 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 harsh working conditions.
