EF LIYY multicore PVC high-flex data cable (unscrn)

EF LIYY multicore PVC high-flex data cables (unscreened) are designed for use in free movement without tensile stress and in drag-chains.

These highly flexible EF LIYY cables work well in data transmission applications where the cable is constantly moving.

Suitable for installation indoors in dry or damp areas. Installation outdoors is not recommended.

These DIN47100 colour coded cables do not have earth wires but are built along the same lines as EF YY/CY high-flex 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.
