Rating scope and manufacturer source

The HSK78G is an engine family used in 1,600, 1,800 and 2,000 kWe generator sets. The 2,000 kWe, 50 Hz value shown here corresponds to the C2000N5CD configuration and the source’s continuous (COP) duty definition. It is not a universal output for every HSK78G package.

Cummins lists N5CD configurations at 50 Hz with direct drive and N6CD configurations at 60 Hz with a gearbox. Do not infer engine speed from electrical frequency alone. Confirm the exact generator model and its data sheet.

What is the Cummins HSK78G?

HSK78G identifies the engine family, while C1600, C1800 and C2000 identify different generator outputs. Cummins lists N5CD packages at 50 Hz with direct drive and N6CD packages at 60 Hz with a gearbox. Compare the exact model, duty, fuel conditions and manufacturer data sheet; the family name alone does not determine output or project compliance.

Match the HSK78G to a gas generator package

For gas generator or CHP projects, Haifeng Machinery can review engine output, alternator frame, voltage, gas train, cooling and controls before package selection.
