Trolleybus model 333


Low-floor articulated four-door trolleybus with a transistor control system based on IGBT-modules by the AC traction electric engine. The reduction of the electric energy is till 35% in comparison with trolleybuses using contactor-resistor control system.

The panoramic windshield provides a better visibility from the driver’s cab. Wide doors, comfortable and rationally located passenger areas in the compartment reduce the time spent for boarding and alighting.

Today the trolleybuses of this model run successfully in the Republic of Belarus and Russian Federation.
