Introduction
Introduction
Our steam turbines, rated 135–160MW, are engineered for conventional steam power plants. With over 100 units of this type already in service across China, we deliver mature, field-proven technology — backed by decades of manufacturing and commissioning experience.
Specification of Condensing Turbine
High-efficiency condensing steam turbine units for power generation. Super-high pressure, single reheat, tandem two-casing two-flow design, 3000 r/min (50 Hz).
