Clad series ME-H
Multiconductor Armour (SWA)
Steel wire armour
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.

(1) Current-carrying capacity of cables with up to three conductors, installed in ducts or directly buried, up to an ambient temperature of 30ºC, according to chart 310.15 (B)(16) of the NFPA 70. As from four-conductors, we’ve additionally applied the correction factor for more than three conductors from the chart 310.15 (B)(3)(a) of the NFPA70.
