en.Wedoany.com Reported - On April 12th, the generator rotor for Unit 2 of the Guizhou Dawan Project in China was successfully inserted in a single operation.

The net weight of this generator rotor is 65.5 tons. The generator's maximum continuous output capacity matches the turbine's maximum continuous output. It possesses the capabilities required by national standards for loss-of-excitation asynchronous operation, leading-phase operation, peak-shaving operation, and unbalanced operation. The rotor insertion utilized two 130/32-ton cranes in the turbine hall along with a set of specialized rotor insertion tools provided by the manufacturer. First, one crane lifted the generator rotor, and insertion was performed with the aid of the specialized tools. For final positioning, both cranes were used in a tandem lift to place the rotor.

At 9:00 AM, the project department conducted a detailed safety and technical briefing. In conjunction with the supervision and construction units, they performed a final condition check before the rotor insertion for Unit 2's generator. After all conditions were confirmed and signed off by all parties, the rotor insertion commenced. At 14:06, the generator rotor smoothly entered the stator bore. The stator bore was clean and free of foreign objects. Confirmed by the supervision, owner, and manufacturer, the generator rotor insertion for Unit 2 was successfully completed.
