Clad series NF-F
Single-conductor up to four-conductor Armour (Tape)
Steel tape armour
Fixed power distribution networks in factories, warehouses, machine rooms, power distribution stations. 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 Installed in aerial trays, gutters or conduits, buried in ducts or directly buried. It has additional mechanical protection.
