TGC-1 PJSC continues sweeping upgrade of the Verkhne-Tulomskaya HPP. In the course of the project, a new working wheel was installed in the turbine pit of hydroelectric unit No.3
The upgrade project provides for increasing the capacity of hydroelectric units while keeping working wheels of the same rotary vane type. The equipment, 4.3 m in diameter and weighing 46 tons, was transferred to its original location using an overhead crane. The working wheel for the Verkhne-Tulomskaya HPP was delivered assembled from the manufacturer's plant, which significantly reduced the time of installation works. The equipment was manufactured by Tyazhmash JSC in Syzran.
“So far this is the third hydroelectric unit at the Verkhne-Tulomskaya HPP to undergo a complete renovation. The work is carried out according to the schedule," said Oleg Tyapinov, Chief Engineer, Kolsky Branch of TGC-1 PJSC.
The Verkhne-Tulomskaya HPP upgrade project includes a complete step-by-step replacement of all hydroelectric units of the plant, of control, safety, and automation systems.
