Traction Power System Solutions

Since 2008, AKTIF has become one of the important players in Railway Traction Power System solutions and has been providing reliable and hassle-free projects for years. We are providing a complete system solution in Traction Power by supplying our own production MV Switchgears together with Dry Type Traction Transformers, Traction Rectifiers and DC Switchgears that we supply from European companies. Aktif, which has expanded its production line in the field of on-board braking resistors, is on its way to becoming an international manufacturer. Therefore, we are a strong solution partner...

MV Switchgears Metal Clad Switchgears Traction TransformersDry Type Traction Transformers SNC series Metal Clad Switchgears are switching and control cabinets manufactured between 1 kV to 36 kV in conformity with IEC 62271-200 standards, they are standing type and made by steel sheet. SNC series metal clad switchgears are two types; • SNC-1 withdrawable circuit breaker • SNC-2 withdrawable type circuit breaker and voltage transformer Main Features • LSC-2B service continuity • PM partitioning • AFLR class internal arc resistant • Accessibility all compartments from front • 3 mm thick sheet...

Rectifiers are used to convert alternating current into direct current used to feed trains. COET offers the most up-to-date product concepts to 750V, 1500V and 3000V DC Traction Transformer substations with its experience in the production of Traction Power Rectifiers for more than 25 years. COET Rectifiers are produced and type tested in accordance with IEC 60146-1-1 and EN 50328 international standards. Main Features • Separate compartment for power and low voltage • Bridges connection: series or parallel • Fixed or withdrawable execution with manual or motorized truck (optional) • AC...

DC Switchgears Negative Panels and VLD DC Switchgears Track-side and Depot Disconnecting Units In a DC Traction System the return circuit (negative) shall usually have high insulation level against earth to limit stray currents phenomena. In case of dangerous overvoltages, the return circuit shall be short circuited to earth. For this purpose a voltage limiting device shall be installed on each negative path. COET Voltage Limiting Device is fully in compliance with EN50526-2 standard, the most severe class (class 4) and with EN 50122-1/2 which defines all the applicable and operating...

PFC System Shunt Reactor Banks DC SwitchgearsDC Disconnecting Units (LBD) In DC Traction Substations one disconnector or load break switch is normally installed downstream each High Speed Circuit Breaker thus allowing, in case of failure, to isolate the circuit breaker granting the safety of the system. The configuration is then completed by a bypass or parallel disconnector switch connecting two feeders and allowing to grant the service continuity in case of failure of one circuit breaker: this disconnector is normally on-load and motorised for remote control. Main Features • Segregated...

PFC System Static VAR Generator Railway Resistors Railway Braking Resistors SVG series IGBT switching compensation systems consist of high technology IGBT drivers and modules. It can perform both inductive reactive and capacitive reactive compensation in both directions. Main Features • Immediate response to rapid and sudden load changes • Easy installation, operation and easy power increase • Thanks to its modular structure, easy material and equipment change, it allows backup • Switching and compensation without causing transients and harmonics • One-to-one independent intervention to the...

Crowbar resistors are used to protect the outputs of power sources in railway systems against the short-time (transient) and long-time overvoltage failures. Output voltage rises very fast (in microseconds) when semi-conductors of power source fail (short circuit) or the control circuit collapses. Protection system fully independent from the control system of power source detects the fast increase of the output voltage and switches the crowbar resistor connected to the power output with the semi-conductor switching system. In this case, crowbar resistor create an over current limited to a...
