Halogen free installation cable JH (St) H. .. Bd, gray fire alarm installation cable JH (St) H. .. Bd red Application: halogen-free installation cable with static screen and improved fire performance for telecommunication and information processing systems. This cable is used for telephone, measuring and signaling, in stations and private branch for telecommunication systems of all classes in dry and wet premises. A laying on, in and under plaster is permitted. The static screen causes a reliable limit of external electromagnetic interference alternating fields. There are no fire damage by halogen-containing gases, the flue gas development is low. Construction: Conductor: stranded bare copper single wire, 6 or 8 mm diameter Insulation: cross-linked polymer HI
