Type 81-553 Metro Trainsets

In cooperation with a Russian partner Škoda Transportation produces new underground train units for the cities of Kiev (a five-car unit consisting of two cars 12 Mt – front, one car 13 Mt – intermediate regular, and two cars 14 Mt – intermediate driving) and Kazan (a four-car unit consisting of two cars 12 Mt – front, one car 13 Mt – intermediate regular, and one car 14 Mt – intermediate driving) where Škoda Transportation takes part in supplying traction and pneumatic equipment.

Most of the electric equipment intended for the drive of the formation is located in the traction container which is suspended below the floor. Every traction container contains four traction inverters each of which is used for the power supply of a separate traction motor. The three-phase asynchronous traction motors are equipped with their own cooling. This guarantees trouble-free operation of the units also in above-ground sections.
