Advantages:
1) Strong and rigid frame structure ensuring less vibration when assemble with the diesel generator set.
2) The generator cooling wind path is shorten, ensuring good heat dissipation effect and lower temperature.
3) Provide substantial cost saving when assembling to any G-Drive engines, especially when assembling with a canopy enclosure or soundproofing system.
Patented Technology:
The stator laminations and the soft-end band fixing structure of stator coil ends with national patent technology
The enameled flat/rectangular copper wires and novel design rotor winding inter-turn insulation structure with national patented technology
Rotor's design using the innovative technology, using all 100% copper flat wire and gained two patents.
Advantage 1 : Increase pole coil's resistance to voltage shock and increase generator's life and reliability.
Advantage 2: Decrease shock to rectifier bridge and increase its life and reliability.
Advantage 3 : Increase exciter reaction speed,and decrease AVR's output current to improve it's sensitivity and life time.
