Tram and Railway Traction

Discover our products related to electric traction

We are involved in both tram and railway traction. Therefore, we offer a wide range of products for various power levels, currents, and applications. We have a broad assortment of components such as: thyristors, diodes, railway cables, and supercapacitors.

What is electric traction?

Electric traction refers to the propulsion of mechanical vehicles powered by electric motors. Typically, traction vehicles (electric locomotives, rail and tram motor cars, trolleybuses) use DC motors powered by electricity delivered via an overhead contact line running along the route, transferred using a pantograph sliding on the wire. Compared to other types of traction (steam or diesel), electric traction has better operational characteristics:

• it is cheaper,
• the vehicles used are lighter,
• it enables large displacements,
• it has a short braking time.

A disadvantage of electric traction is the high cost of route electrification.

How is the traction network powered?

The power supply of electric traction, regardless of the type of current or voltage level, is characterized by an electrical circuit. This circuit is built from specific elements, each playing a role in the power system. These elements include:

• Traction substation – its purpose is to convert current and voltage into levels suitable for powering traction vehicles.
• Power cable – responsible for transmitting energy from the substation to the traction network.
• Overhead line – composed of the contact wire and a catenary wire that supports it. The contact wire connects with the pantograph. The function of the overhead line is to deliver energy to the vehicle through the pantograph mounted on the locomotive.
• Traction vehicle – converts electrical energy into mechanical, thermal, and light energy.
• Rails – referred to as the return network and carry a negative potential. They are connected with transverse and longitudinal connectors.
• Return cable – its task is to connect the rails to the traction substation.
