Cummins Generator
 
 

This series’ diesel generating set which power section uses Commins NTA or KTA series diesel engine has the characteristics such as slight volume, large power and low noise. The generator selects and matches the domestic famous series non-brushes electrical machinery which has the function of auto-regulate voltage and when the water temperature is high, the oil pulls down, the overspeeding reports to stop the engine off, self-starting, long-distance operation, 485 connections. The low noise box body independently develops by our factory, reasonable design, the noise reduction performance is high. Mobile power plant’s undercarriage system use the trapeziform wheel to change the transmission system, and adopt the gas checks and the hand checks double braking system, has the good smooth running and cross-country performance.
The unit has artistic outlook, compact structure, light weight, fine performance, reliable movement and easy to operate. And its performance index conforms to the national standard stipulation.
