Recently, the engineering team is preparing to upgrade the available 2x800KW cross-flow Turbular Bulb and 2x160KW Kaplan flow hydropower stations in domestic, into modern hydro power stations with 2x1200KW+600KW Kaplan flow units. The project was originally completed in 1997, which is 28 years ago. Because it is so old, the actual operating efficiency is relatively low, there is a lot of water waste, and it can not reach the original normal working efficiency. Therefore, the original owner entrusted us to come and inspect and review the replacement proposal, and then further implement it. The previous construction site was changed to the actual site to improve the operating efficiency. Therefore, after the on-site inspection by the expert team, it was transformed into two 1.2MW plus one 600KW axial flow units to achieve the purpose of efficient operation.
