Using Cummins K series engine, the original designed built-in multi-stage vibration damping system can effectively eliminate the vibration of the unit during operation, so that the control system and electrical components are better protected; in extremely harsh environments, it can also provide very reliable of electricity. ​​ 1. After several Cummins generator sets are connected in parallel, quite a high-power generator set supplies power to the load. The number of generator sets can be determined according to the size of the load (the generator set consumes the lowest fuel under the working condition of 75% of the rated load) , so as to achieve the purpose of saving diesel oil and reducing the cost of the generator set. Especially with the continuous development of the economy, energy is becoming more and more tight, saving diesel has become quite important. 2. Realize the uninterruptible power supply to ensure the normal production of the factory. When the unit is switched to use, the standby generator set can be turned on first, and then the original running generator set can be stopped, and there is no need for power failure in the middle. 3. Multiple Cummins generator sets are connected in parallel. When the load suddenly increases, the current impact is equally shared by multiple generator sets, so that the force of each generator set is reduced, the voltage and frequency are stable, and the service life of the generator set can be extended. 4. Cummins is easy to find warranty all over the world, even in Iran and Cuba. And the number of parts is small, the reliability is high, and the maintenance is relatively convenient
