These armoured halogen-free and flame retardant individually screened control and connecting cables with twisted pairs are especially used for EIA RS-485 applications, computer systems, the transmission of analogue and digital signals in processor-controlled equipments. It provides low capacitance with Foam PE insulation and transmits the datas at longer distances. And individually screened and overall screen screen provides protection against external electrical interferences. Halogen-free cables are used in the closed environments where low corrosive gases and low smoke density must have in case of fire. The armour protects the cable from mechanical shocks. They are for indoor and outdoor installation, in dry and wet locations; on racks, trays, in conduits.
