Steel wire armour
Fixed power distribution networks in factories, warehouses, machine rooms, power distribution stations. For Alternating Current (60Hz), for single-phase systems (110V), three-phase systems (190/210V) and systems with voltages up to 600V. Installed in aerial trays, gutters or conduits, under roof or ladder under roof, buried in ducts or directly buried. It has additional mechanical protection.

(1) Calculation of Inductive reactance valid for two-conductor, three-conductor, and five-conductor cables. (2) Calculation of Inductive reactance valid for four-conductor cables. (3) 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.
