PUR EF LIYY multicore high-flex data cable (unscreened) is designed for use in free movement without tensile stress and in drag-chains. Suitable where protection against electro-magnetic interference is not required.
These tough highly flexible PUR EF LIYY cables work well in data applications where the cable is constantly moving, particularily in arduous environments. The PUR sheath provides increased mechanical and chemical resistance when compared to standard PVC.
Suitable for installation in dry, moist or wet areas and where exposed to harsh mechanical strain or dragged over sharp/rough surfaces.
Highly flexible DIN47100 colour coded cables do not have earth wires but are built along the same lines as EF YY/CY superflex control cables, generally in smaller conductor sizes. If there is need for protection against electrical interference please see our range of EF LIYCY data cables.
