series RM
Multiconductors Cable
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.
