These halogen-free and flame retardant industrial automation process connecting cables with twisted pairs are especially used at CAN (Controller Area Network) fieldbus systems for the transmission datas between processor-controlled equipments and main system. And also the tinned copper wires braided screen provides protection against external electrical interferences.alogen-free cables are used in the closed environments, at industrİal places where low corrosive gases and low smoke density must have in case of fire.
