CY cables, also known as screened flexible cables, are used as interconnecting cables for measurement, control or regulation in control equipment for assembly and production lines, conveyors, and computer units. They are typically used in applications requiring interference-free transmission due to their multi-core flex, tinned copper wire braid (TCWB), and polyethylene terephthalate (PET) separator, which protect it from external electromagnetic influences which could degrade accurate signal transmission. The CY cable's TCWB and PET also provide protection against light mechanical stress.
These cables are suitable for flexible use when temporarily moved without tensile stress. CY cables can be used outdoors when protected against direct sunlight, and in dry or moist conditions (including oil-water mixtures) indoors.
CY control cables are not suitable for fixed wiring applications requiring compliance with the requirements set out in BS7671.
These screened flexible multi-core control cables have a voltage rating of 300/500V.
CY cable specifications for construction
|CY LSZH||CY PVC||CY PVC (UL &
|Copper conductor||Class 5 flexible||Class 5 flexible||Class 5 flexible|
|Insulation||Halogen free Type TI6||PVC Type TI2||PVC to UL 1581|
|Binding tape||Polyester tape (PET)||PET||PET|
|Sheath||LSZH Type TM7||PVC Type TM2||PVC to UL 1581|
Whilst both of the PVC sheathed CY cables are widely used, the UL and CSA approved version tends to be more widely used for export-orientated machinery destined for the North-American market.
CY cable selection
In addition to the various types of construction, CY control cables are available in a wide range of sizes. Eland Cables' technical team is available to discuss your specific application and to assist you with the selection of the right cable. Calibrated CY cable glands and other cable accessories are also available.

Larger core sizes and cross-sectional sizes are also available. The part numbers and specifications for the CY LSZH cable and the CY UL/CSA approved cable may be different and you should refer to the datasheet for full information.
Our wider range of flexible control cables includes the unscreened YY cable for light mechanical stress applications and the SY cable with galvanised steel wire braid providing mechanical protection for medium tensile stresses. LiYY cable and the screened LiYCY cable are also available as are LSZH equivalents and a range of variable frequency drive VFD cables.
