Transformer type ОДЦЭ-2000/25П-У1

The single-phase traction transformer is designed to convert the voltage of the contact network into the voltage required for the traction motor circuits and auxiliary systems of AC electric trains operating at 25 kV for suburban and local services. Oil circulation is provided by an electric pump. The electric pump is mounted on the transformer and supplied as a complete assembly with the transformer. Climatic version — У, placement category — 1, according to ГОСТ 15150 and ГОСТ 15543.1.
