5. Common FAQ

5.1 What is the actual usage difference between prime power and standby power of KT38-G generator set?

The 500kW/625kVA prime power is the rated continuous operating power of the unit, supporting 24-hour long-term uninterrupted power generation and allowing short-term 10% overload operation. It is mainly used for off-grid main power supply, mining continuous power supply and long-term industrial high-load production scenarios. The 560kW/700kVA standby power is emergency peak power, only designed for short-time power supply when the municipal grid fails. Long-term continuous operation at standby power is strictly prohibited, which will cause excessive engine load, accelerated wear of internal moving parts, increased fuel consumption and shortened overall service life of the Cummins diesel generator set. Users must select the corresponding power mode according to actual working conditions to ensure stable equipment operation.

5.2 What core advantages does KT38-G have over ordinary 625kVA diesel generators?

Compared with conventional ordinary 625kVA generator sets on the market, the KT38-G model has obvious comprehensive advantages. First, it adopts 37.8L super large-displacement 12-cylinder V-type heavy-duty engine, with 700kVA ultra-high standby power reserve, far stronger overload resistance and high-load sustainability than ordinary inline six-cylinder units. Second, the mature full mechanical PT fuel system has extremely low failure rate in dusty, humid and high-temperature harsh environments, with stronger environmental adaptability than electronic control generators. Third, the heavy-duty reinforced structure and genuine Cummins supporting accessories greatly improve equipment durability, reduce later maintenance frequency and comprehensive operating costs, and have higher cost performance for long-term large-scale industrial and engineering applications.

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

The IP23 dustproof and waterproof protection grade can effectively block large solid dust particles and all-directional splashing water, fully adapting to open-air construction sites, dusty mining workshops, semi-outdoor equipment rooms and humid coastal working environments. The H-grade high-temperature resistant insulation material can maintain stable insulation performance in the temperature range of -20℃ to +45℃, and will not age or break down after long-term high-load and high-temperature continuous operation. Matched with the professional closed-circuit forced water cooling system and vibration-resistant heavy-duty structure, the unit can operate stably in extreme high-temperature, low-temperature, dusty and humid complex environments, realizing all-weather reliable power supply for various key scenarios.
