Electrical Engineering Factory ESTEL is a developer and producer of a wide range of power converting equipment for railway transport and traction substations. It was founded in 1870 and is situated in Tallinn, Estonia. The company combines long-term experience with unique modern development in its field.

ESTEL produces devices for traction substations such as inverters, rectifiers and transformers. The inverter is designed to transfer the excess power from the contact DC network to supply AC network for main railway traction substations and to provide braking of electric locomotives on mountain slopes.

ESTEL’s series rectifiers are designed to convert AC to DC for mainline railway traction substations. They are equipped with microprocessor-based protection, with diagnostics based on production ESTEL controllers and an operator panel with LCD monitor. Rail operators can use the internal oscilloscope to continuously monitor parameters, including current, voltage, diode temperature and alarm waveforms.

ESTEL also manufactures traction converters for asynchronous electric locomotive motors and static converters for electric locomotives. All products made by ESTEL are equipped with self-produced power semiconductor devices which meet all European standards and possess high quality and technical rates. The company’s own design office allows it to carry out the development of unique equipment according to special requirements of the customer.

In addition, ESTEL produces reversible converters for electric locomotives; converter units for rolling stock; electric locomotive oil pump engine power supply unit; rectifiers for diesel trains.

Electron Corporation is a manufacturer of up-to-day passenger electric transport: trams, trolleybuses and electric buses.

Electron trams are low-floor cars with an air conditioning system, reduced vibration and noise level. Cars are intended for tracks of different gauge.

Electron trolleybuses are of a superior comfort. Their main advantage is an autonomous motion, i.e. without an overhead line, at a distance of up to 3 kilometers.

Electron electric bus is an ecological urban transport of a new generation and an example of efficient use of cheap electric power for passenger transportations. A distance run of the bus without recharging of tractive storage battery is 3,000 kilometers.

Electron electric transport meets modern European standards, including high safety and comfort level. Read more about Electron at www.electron.com.
