Clad series EFC-H

Steel wire armour

Flexible Cu 1 up to 300mm²
Includes PE conductor

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 (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, under roof or ladder under roof, buried in ducts or directly buried. It has additional mechanical protection.
