Traction Power Distribution

Within the context of traction power, we provide products and engineering services for all electrical systems from medium voltage to vehicle DC auxiliary feed. Aktif Engineering designs the project and supplies the equipment for DC power for the trains used on rail systems including switching at Medium Voltage level with Medium Voltage Switchgear and transfer to Traction Rectifier Transformers, reduction of voltage level to low voltage with transformers, transformation of AC voltage to DC voltage with inverters and switching of DC power required by trains with DC Cubicles.

Aktif’s Signature on 19 km Railway System of Antalya!

The railway system constructed for access to EXPO was introduced during the opening ceremony held in Antalya.

Antalya Metropolitan Municipality has constructed 19 kilometers long rail system for access to EXPO 2016 area in a very short period of 5 months with the support of Ministry of Transportation. Aktif Group has the main role in construction of all Traction Power systems and switching equipments of this 19 kilometers long line.
Aktif Group produces MV Switchgears its own factory located in Ankara, that is distributed to Traction and auxiliary transformers completed especially with Tesar who is one of the world leaders in the railway systems. COET – FRIEM Group’s broad product of Traction Rectifiers and DC Switchgears which one of the most important equipment, has been used in Antalya Railway Project of substation. COET is one of shareholders in Ankara Factory of Aktif Group.
So Aktif has been in the whole project from MV to catenary energy distribution. At the end of the route for rail system transports will be located a warehouse and a maintenance station and on this part the supply systems undertake by Aktif Group.

The Equipments are used throughout the project;
  • 10 pcs. 2750 kVA Traction transformers
  • 3 pcs. 400 kVA Distribution transformers
  • 7 pcs. 250 kVA Distribution transformers
  • 20 pcs. 75 kVAr Shunt Reactor System
  • 10 pcs. 2500 kW Traction Rectifiers
  • 10 pcs. Incoming Cubicles
  • 40 pcs. DC Feeder Outgoing Cubicles
  • 10 pcs. Voltage Limiting Devices
  • 10 pcs. Main By-Pass and Disconnector Cubicles
  • 52 pcs. 36 kV SMC Metal Clad Switchgear


Friem Traction Rectifier

Air cooled Diode Traction Rectifier is designed for Train Lines, Metro Lines and Tram Lines. The range is completed with complete line of inverters and bidirectional converters, using thyristor, IGBT or GTO, to comply with the recent requests of braking energy recovery, Traction converters are fully comply with IEC or ANSI/IEEE standards and the most severe standards for heavy traction service.




We are attended to the Hannover Messe 2016 - Industry and Industrial Exhibition

The fair was held between 25-29 April 2016 in the city of Hannover in Germany and this fair brought together international business partners on issues such as automation of industry, renewable energy, improve energy efficiency studies, supply and services.
The fair made a grand opening with Barack Obama's participation and Aktif Group brought together the wide range of products with visitors at the Hannover Messe Industry and Industrial Exhibition fair with 6,500 participants from 70 countries.
We would like to express our sincere thanks for taking time to visit our stand at recent Hannover Messe 2016.
