Areas of Use

Used for transmission of the data signal in computer, information and communication systems as well as process control for computer systems and terminals. HFFR versions are less flammable in case of fire, mostly self-extinguishing, have low smoke density and they do not emit poisonous and corrosive gasses during a fire.
