Product Advantages
What sets TEBAOFLEX PVC Control & Data Cable apart in service.
Four Designations, One Family
Unscreened LiYY, screened LiYCY, numbered-core YY and steel-braided YSLYSY cover signal, data and control wiring from the cabinet to the machine.
Fine-Stranded Copper
Fine-stranded bare copper conductors keep the cables flexible for routing through cabinets, ducts and machine frames.
Screened for EMC
LiYCY carries a tinned copper braid over the whole core bundle, typically 70 % to 85 % optical coverage, for signals near drives and contactors.
Steel Braid Protection
YSLYSY places a galvanised steel wire braid between a grey PVC inner sheath and a transparent outer sheath, so braid damage can be seen during inspection.
Clear Core Identification
DIN 47100 colours on LiYY and LiYCY; black cores with white numbers and a green/yellow earth from three cores on YY and YSLYSY.
Indoor Temperature Range
-5 °C to +70 °C when flexed on all four types; fixed installation down to -30 °C (LiYY, LiYCY) or -15 °C (YY, YSLYSY).

Application Scenarios
Where PVC Control & Data Cable from TEBAOFLEX is installed.
Control Cabinets and Panels
LiYY and LiYCY wire sensors, switches and PLC inputs and outputs inside crowded cabinets, with many cores in a small outer diameter.
02Automation and Process Control
The tinned copper braid of LiYCY protects analogue and digital signals from frequency converters, contactors and nearby power cables.
03Instrumentation and Measuring Devices
Weighing scales, measuring instruments, encoders and electronic assemblies wired with unscreened LiYY or screened LiYCY.
04Machine Tools
YY interconnects control cabinets and machine tools; numbered cores make a circuit diagram easy to follow when one cable carries many signals.
05Conveyors and Assembly Lines
YY and YSLYSY run along conveyors, assembly and production lines to sensors, valves and small motors.
06Exposed Machine Positions
Where swarf, tools or workpieces can strike the cable, the steel braid of YSLYSY spreads impact and crushing loads.
How to Choose PVC Control & Data Cable
Four decisions specify the right cable the first time; send them with your RFQ and our engineers confirm the type designation.
Screen or Braid
No screen (LiYY, YY), a tinned copper braid against interference (LiYCY), or a galvanised steel wire braid against impact and crushing (YSLYSY).
Signal or Control Voltage
LiYY and LiYCY are for signal circuits, 250 V to 500 V peak, not for power; YY and YSLYSY are rated 300/500 V for control circuits.
Cores, Size and Identification
Count circuits and spares, pick 0.14–1.5 mm² for signals or 0.75–2.5 mm² for control, and DIN 47100 colours or numbered cores.
Movement and Environment
Fixed or occasional flexing indoors; protect YY and YSLYSY from sunlight outdoors, and confirm drag-chain or continuous motion with our engineers.
Standards & Certifications
ISO 9001 quality management for cable production; ISO 14001 and ISO 45001 for sales and related management. UL and cUL (flexible cord), VDE (EN 50525-2-21), Korea KC, China MA and US MSHA approvals cover the certified types; CE is a third-party verification of conformity (VoC).

Quick answers about PVC Control & Data Cable from our engineers.
01What is the difference between LiYY, LiYCY, YY and YSLYSY?
LiYY and LiYCY are small data and signal cables with DIN 47100 colour-coded cores for electronic equipment, instrumentation and automation; LiYCY adds a tinned copper braid screen. YY and YSLYSY are 300/500 V control cables with black numbered cores for machine tools, conveyors and production lines; YSLYSY adds a galvanised steel wire braid between two PVC sheaths for mechanical protection.
02Which cable do I need where there is electrical interference?
Choose LiYCY. Its tinned copper braid covers the whole core bundle and protects signals near frequency converters, contactors and power cables when the braid is clamped over its full circumference in an EMC gland or screen clamp. The steel braid of YSLYSY gives some shielding effect, but its main job is mechanical protection.
03Can these cables be used for RS-485 or Modbus?
LiYCY can carry short, low-baud RS-485 links inside a cabinet. It is not a 120 Ω bus cable, so a bus that runs hundreds of metres or at higher baud rates needs a dedicated 120 Ω data cable. LiYY is unscreened and not built to a controlled impedance; use it for low-frequency signal and control wiring.
04Can LiYY or LiYCY carry mains or motor power?
No. LiYY has a 250 V peak operating voltage and LiYCY 350 V or 500 V peak, for signal circuits only. For 300/500 V control circuits that feed contactors, valves or small motors, choose YY, or YSLYSY where the cable needs mechanical protection.
05Are these cables suitable for drag chains or outdoor use?
No. All four are built for fixed installation and occasional flexing or free movement without tensile stress, not for continuous drag-chain, torsion or reeling duty. LiYY and LiYCY are for dry and damp indoor rooms, and YY and YSLYSY need protection from sunlight outdoors. Tell us the motion and environment and our engineers will propose a suitable construction.
06What should I send for a quotation?
Send the designation, core count and cross-section, numbered or colour-coded cores, the length or drum lengths, fixed or moving installation and the environment, how the screen or braid will be terminated, the sheath colour and any standards, markings or test documents your project requires. Our engineers confirm the construction on the TEBAOFLEX datasheet issued with your quotation.
