Cable for telecommunication and safety systems with special application conditions especially for systems subject to vibration, such as cables laid in vicinity of rail track region with cable cores

摘要

The cable is designed, so that the insulated conductors of the groups of four, the pairs, or the other twisted groups consist of strands. In the central region an inner damping element is arranged. In addition the insulated conductors (1) are so fixed, that the cores of the groups of four, the pairs, or the other twisted groups lie loosely against each other. In certain cases several of these basic elements are led together, and the basic elements, arranged in layers are surrounded by damping intermediate elements. The corresponding configuration is sleeved by a casing.
