Gas-Turbine Power
For over two decades CYDG (SSE: 603950) has machined the cylinder blocks and heads at the heart of China's leading engines — for Cummins, Dongfeng, Yuchai and BYD. Today we bring that same manufacturing depth to gas turbines and power equipment: firm power from 0.2 to 448 MW for data centers and industry worldwide.
