EF CY screened high-flex PVC control cable is designed for use in free movement without tensile stress and in drag-chains. The tinned copper wire braid screen provides protection against electronic interference.
These highly flexible EF CY 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 protection against electrical interference is not required please see our range of EF YY cables.
