Signalling cable, optimised for installation, transversally watertight, flame-retardant and rodent-proof for railway control centres and surveillance systems, etc., suitable for installation in open air, in the ground, in cable tray channels, and for laying in tunnels and buildings.

The cable is halogen-free, flame retardant and with low smoke density. It is suitable for installation in tunnels and in areas with special hazards caused by fire propagation.

VDE approved and system-tested sleeves are available for this cable.
