Successful installation of the Rotor of the generating unit No 3 of the Lai Chau Hydropower Plant Project

At 10.45 on September 06, 2016, the generator rotor of the unit No 3 of the Lai Chau hydropower plant project was successfully installed on its foundation by the Vietnam Electricity after 2 hours and 40 minutes to move into position.

The generator rotor of the unit No 3  is of  1,000 tons in weight , 15.587 m diameter and  2.816 m in height. It is one of the heaviest structure of the equipment installed at site. Before installing the rotor, the contractor has completed the installation of the turbine, stator, crane ... This is an important milestone, the reprequisite to commission the equipment   system, to meet the target of generationg the unit No 3 of the Lai Chau hydropower plant project  in November 2016 and inauguration of the whole project in December 2016.
