Steel wire armour
Extended performance to preserve electrical integrity in direct fire conditions. This is verified in different tests where the cable is exposed to direct fire for 3 hours at 950ºC, direct fire and water spray, and direct fire and mechanical shock simulated by repetitive striking. For fixed power distribution networks for alternating current (50/60Hz), for single-phase systems (220/110V), three-phase systems (380/190V) and systems with voltages up to 1kV. For Direct Current, used in systems with voltages up to 1.5kV 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.
