Clad series RM-H
Multiconductors Armour (SWA)
Steel wire armour
Fixed power distribution networks in factories, warehouses, machine rooms, power distribution stations. 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 aerial trays, gutters or conduits, under roof or ladder under roof, buried in ducts or directly buried. It has additional mechanical protection.
