Traction Rectifier Transformer | High-Efficiency Power Solution for Railway Systems

Traction Rectifier Transformer | Reliable Power Conversion for Railway and Metro Systems

The traction rectifier transformer is a specialized power conversion device designed to transmit electric energy from a three-phase AC power system to two single-phase traction lines with independent loads. These lines supply stable power to up and down locomotives, making the transformer widely used in urban rail transit, intercity express trains, and mining transport vehicles. The rectifier unit provides continuous and stable DC traction power to ensure reliable train operation.

A complete traction rectifier unit typically consists of a traction rectifier transformer and a rectifier. It adjusts the AC voltage on the grid side to the required DC voltage on the valve side to meet the power demand of traction loads. Current market configurations mainly include 12-pulse and 24-pulse rectifier systems, which offer high efficiency and low harmonic distortion. Our company manufactures traction rectifier transformers with superior performance, optimized energy efficiency, and excellent stability, suitable for modern railway power systems.

All products are manufactured in accordance with international standards, including IEC 60076-11 (Power Transformers – Part 11: Dry-Type Transformers) and IEC 60529 (Degrees of Protection Provided by Enclosures – IP Code), ensuring safe, durable, and reliable operation.
