1st Stay Cone Installed

      7th February 2017, the company started to lift and install the stay cone of the 1st Unit turbine.
     
2月7日,桑河二级水电站首台机组座环开始吊装。
     
The stay cone consists of inner stay cone, outer stay cone, lower part cone and the support structures. This time the lower part of the inner stay cone, lower support and horizontal support, which have been assembled and welded at the erection bay, were lifted into the pit to install. The installation of the 1st stay cone marks that the progress of Lower Sesan 2 Hydropower Project turns from civil construction stage into mechanical-electrical equipment installation stage.
     
座环由内环、外环、外环后段及上、下支柱组成;本次吊装为座环内环下半圆、下支柱及水平支撑在安装间组拼、焊接完成后的部件,标志着桑河二级水电站由土建施工转入水轮发电机组安装阶段工作。
