EF YY high-flex PVC control cable (unscreened) is designed for use in free movement without tensile stress and in drag-chains. Used where protection against electrical interference is not required.
These highly flexible EF YY cables work well in control applications where the cable is constantly moving.
Suitable for installation indoors in dry or damp areas. Installation outdoors is not recommended.
Highly flexible control cables are built along the same lines as YY/CY control cables but with finer stranded conductors. If there is need for protection against electrical interference please see our range of EF CY cables.
