Application
As a railway signalling cable, in railway control centres, surveillance systems and similar facilities, provided that the use of special signalling technology cables (e.g. PZB cables) is not stipulated.
The combined signalling cables are suitable
- for special use in safety installations
- for energy transfer in a cable, especially when, for the star quads, high symmetry with one another is required against external interferences and against earth potential, as is called for by AF and digital transmission.
- for transmission of direct current at an operating voltage of ≤ 600 V or of alternating currents ≤ 420 Veff.
- for especially long railway control distances during low-frequency (AF) or digital transmission.
- for earthing the cable screen on both sides according to the relevant requirements of DB AG.
The cables should be used where they provide benefits in a technical and/or economical sense.
