1. Working environment: the altitude is not higher than 1000 m; ambient environment temperature is -5℃~+40℃.
2. Noise requirement: low power range:(not higher than 500kW), the noise is required within 65~75dB(A)/7m; high power range:(above 500kW) noise is required t within 75~90dB(A)/7m.
3. Safety measures: rain, sand, rust and corrosion proof.
4. Performance guarantee: Stable operation; and prime generating set can operate on load for 500 hours continuously, and non-fault time averages at 2000-3000 hours.
