Application
For general cabling in telecommunication systems of DB AG, in particularly along tracks.
The cable is to be preferred for laying along or in the rail foot at train speeds up to 160 km/h or in further areas with increased vibration loads according to the applicable regulations, but also for laying in the ground, in pipe conduits and trough channels.
Not approved for use as overland line.
The cable is resistant against impact, vibration, and shock loads and features an UV-resistant outer sheath.

Tensile force only valid when cable sheath and cable core involved.
The bending radius one-off is for professionally installed cables, unique molding.
The bending radius repeated applies to dynamic bending operations eg during the installation.
Other designs, fitted lengths and larger delivery lengths on request.
