Propulsion System
We have more than 50 years of experience in design production and service of AC electric drive systems for locomotives. TEC engages in R&D and manufacturing propulsion systems for both electric and diesel Locomotives. Its products portfolio is developed from thyristor based rectifiers to the latest IGBT based AC traction system in the past decades.Today, TEC provides integration and one-stop service for the entire electric system, including driving system, network control system and auxiliary power supply. More than 1500 sets of TEC propulsion system have been installed in AC locomotives.
