Rail transit traction substation is dedicated power supply equipment for metro, light rail, tram and high-speed railway systems. It converts AC grid power into DC traction power to supply rail vehicles. Available in traditional building type and factory prefabricated containerized structure. Integrated with traction transformers, rectifier units, high/low voltage switchgears, relay protection and SCADA monitoring system. Features stable output, fast fault response, high safety and low electromagnetic interference. Widely applied in urban metro, light rail transit and intercity rail projects. Customized voltage level, power capacity and prefabricated layout solutions for global rail transit engineering projects.
