LiYCY cable is a typical multi-core shielded control flexible cable designed for automation scenarios in industrial applications with excellent resistance to electromagnetic interference (EMI), oil resistance, and flexibility. It is widely used for signal transmission and power connection of sensors, servo motors, robots, and other equipment.
LiYCY Cable Structure
| Structural Layer | Materials & Properties |
| Conductor | Multiple strands of ultra-fine bare/tinned copper wire stranded (according to IEC 60228 Class 5) ensure high flexibility and low resistance. |
| Insulation | PVC insulated with color separation (e.g. brown, blue, black, etc.) for easy core identification. |
| Shielding Layer | Tinned copper wire braided shielding (coverage ≥80%), effectively suppressing electromagnetic interference. |
| Jacket Layer | Gray/black PVC outer jacket, oil-, acid- and alkali-resistant, flame-retardant (according to IEC 60332-1). |
LiYCY Meaning
LiYCY is the abbreviated designation of the cable type, which follows the naming rules of the German standard DIN VDE 0281 and the European standard HD 22.4. Each letter stands for its specific construction and characteristics. Here is what LiYCY means:
- L for multi-core cables (German: Leitung, meaning “conductor”).
- i indicates that the core insulation is PVC (polyvinyl chloride).
- Y means the outer sheath is made of PVC (polyvinyl chloride).
- C means the cable has a shield (usually a braided tinned copper wire shield).
- Y again indicates that the outer sheath is made of PVC (polyvinyl chloride).
This type of cable is suitable for use when transmitting multiple signals or power, and has excellent oil resistance and flexibility. Similar cables under the same standard are LiYY and LiYCY-JZ. The difference between LiYY and LiYCY is that LiYY does not have a shield in its construction.
LiYCY Cable Common Application Scenarios
Industrial Automation: PLC control systems, sensors, servo motor signal transmission.
Robotics: robotic arm joint cables, encoder connection lines.
Machine Tool Equipment: CNC machine tools, limit switches, solenoid valve control lines.
Other Fields: stage lighting control, medical equipment, rail transportation signal system.
