Case Studies  

"Tsankov Kamak” Hydro Power Plant

The National Electrical Company invested heavily in a project that had a value of nearly 250 million euro. The main contractor was Va Tech Hydro, which later on became Andritz Hydro, Austria. The scope of work dedicated to KZU was the fabrication of pipelines with length of ….. m and diameters ranging from 2600 mm to 4100mm. The most difficult part of the job was the “Y” connection of pipes with diameter of 4100mm and the transition from larger diameter to smaller diameter. After five years of work, the job was completed and now “Tsankov Kamak” supplies Bulgaria with clean and cheap electricity.
