1 Two configurations, one platform
TC builds hydro generators in both vertical and horizontal configurations. Vertical sets run up to 20 MW on frames to 4,250 mm; horizontal sets up to 6.3 MW on frames to 2,150 mm — covering the small and medium hydro range end to end, and matching any turbine in our Francis, Kaplan, Pelton and tubular lines.
2 Bluetooth rotor temperature monitoring
Buried rotor sensors can't be read continuously on traditional sets — so the rotor runs blind. TC's wireless rotor temperature system transmits readings from the rotating rotor via bluetooth to the monitoring screen: real-time values, no slip-ring wear, no wiring across the air gap. The technology is protected by national patents and is available on new sets and as a retrofit.
3 Insulation that survives the site
Stator coils are wound in-house and consolidated by vacuum pressure impregnation (VPI), then cured in a temperature-controlled oven. Whole-stator drying before shipment keeps moisture out of the insulation system — the difference between a generator that tests well in the hall and one that holds up years later in a humid river valley.
4 Tested before it leaves the hall
Every generator passes through the in-house test center: high-voltage DC testing of the winding, instrumentation checks, and run-in on the test bench. Rotors and key castings are inspected by dye penetrant and ultrasonic testing before machining. The objective is simple: nothing on site should be the first time it runs.
TC's hydro-mechanical manufacturing base has delivered more than 300 generating sets to over 100 power stations, with exports to 10+ countries across North America, South Asia and Africa. TC took part in drafting China's national standard GB/T 50700-2011, Technical code for renovation of small hydropower stations.
