Standart: BS 5308-1
Description: PE insulation • pairs stranded in layers • static screen • sheath of PVC
These cables are used for computers and process control in industrial plant. The screen of metal foil protects the circuits from external interfering signals. The low operating capacity makes possible data transfer to long distances. The cables are suitable for fixed installation in dry and wet premises as well as for outdoor installation on the walls of buildings. The use of these cables for power installations and underground installation is not permitted.
