The right solution for your needs: power supply, control functions and data transmission for rolling stock

Increasing urbanisation and progressive digitalisation are constantly placing new demands on railway technology. The demand for transport systems is growing with increasing population density. And with it the expectations for safety and reliability of rail transport. Cables and wires for railways must comply with special safety regulations and fulfil functions in order to be approved for rail vehicles. With the extensive portfolio for railway technology from LAPP, you receive tested and certified system solutions from a single source.

What special requirements must cables and wires for rail transport meet?

The high availability and smooth operation of rail vehicles depends largely on the cables and wires used. Whether power supply, data transmission or the control system: reliable connection solutions enable smooth operation and safe transport.

Cables and wiresfor rail vehicles must have special properties in order to be approved for rail transport. The unrestricted safety of passengers and personnel is the decisive factor. For this reason, fire protection in rail vehicles is treated with great importance and regulated in Europe in the DIN EN 45545-2. Materials and components for rail vehicles are subject to clear specifications.

According to DIN EN 45545-2, railway cables and connection solutions must have the following essential properties: 

In the event of a fire, the products used do not contribute to fire propagation and prevent additional damage to people and materials. In addition, the products have to be able to withstand external influences such as stone chipping, torsion or strong vibration waves that permanently affect them.

Extreme climatic conditions during operation also place high demands on the material properties of cables, wires, cable glands and connectors. Most components must therefore withstand temperatures ranging from -50° to +120°C.
