Clad series FM-H

Steel wire armour

Flexible Cu 1 up to 4mm²
Up to 48 Conductors

Control, signalling, measuring and protective equipment, electric controls of home installations. Use in closed environments with a high concentration of people (airports, hospitals, trains, cinemas, shopping centers, tunnels) and in control rooms with electronic equipment sensitive to the exposure of corrosive gases. Installed in conduits, trays, cable ladders, in direct open air or indoors, buried in a trench or in ducts. It has additional mechanical protection.
