Clad series MH-H
Two-conductor to four-conductor Armour (SWA)
Steel wire armour
Fixed power distribution networks in closed environments with a high concentration of people (airports, hospitals, trains, cinemas, shopping malls, tunnels) and in control rooms with electronic equipment sensitive to exposure to corrosive gases. For Alternating Current (60Hz), for single-phase systems (110V), three-phase systems (190/210V) and systems with voltages up to 600V. Installed in conduits, trays, cable ladders, in direct open air or indoors, buried in a trench or in ducts. It has additional mechanical protection.

(3) Three single-conductor cables displayed in a trefoil in contact with each other. (4) Calculation of Inductive reactance valid for two-conductor, three-conductor, and five-conductor cables. (5) Calculation of Inductive reactance valid for four-conductor cables. (6) 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.
