(1)Compact structure: light weight, small size, easy installation
(2)High transmission efficiency: measured according to the test:
      Single-stage efficiency: η = 0.97-0.98
      Two-stage efficiency: η = 0.94-0.96

(3) Power range: 1.37-500 kW power up its drive
(4)Transmission ratio: Single-stage ratio: i = 4-10
                                   Two-stage ratio: i = 25-100

                                                          Three -stage ratio: i=180-2000
(5)Smooth operation, low noise: planetary transmission with a torque characteristics of the branch, compared with the fixed gear axis, the circumferential speed is decreased. To enable the planetary wheel load balanced allocation between. Using a reliable floating mechanism to reduce vibration and reduce noise.
(6)Long life: The main parts are made of high quality alloy steel through a quenching or nitriding steel. Greatly improve the mechanical properties and wear resistance, and therefore, under normal and reasonable conditions of use, long life, high reliability characteristics.
(7)Anti-leakage: the body does not leak lubricant reducer.
