Integrated monitoring cores from 5x4 on


ignalling cable, optimised for installation, transversally watertight, flame-retardant 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, and therefore suitable for installation in areas with special hazards caused by fire propagation.

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