TFW & STC Alternators
Zhiqiang manufactures TFW brushless alternators (18–600 kW, Class H insulation, IP21) and STC/ST alternators (3–64 kW, Class B) in-house — full copper winding, AVR-equipped, and factory matched to Yuchai engines. Browse all 46 models below.
Our own alternators ship inside the generator sets we build rather than on their own — see the generator set catalogue for the complete sets.
