LiYCY Cable
The LiYCY Cable is a high-performance 250V flexible multi-core screened data transmission and instrumentation cable engineered specifically for signal connection between electronic devices, computer systems, and process control units operating under demanding electromagnetic compatibility (EMC) requirements.
What is LiYCY Cable?
The LiYCY cable is a low-voltage, screened and unarmored flexible multi-core signal and data transmission cable featuring Class 5 fine-stranded bare copper conductors, PVC insulation, a tinned copper wire braid (TCWB) screen, and a grey PVC outer sheath complying with VDE 0482-332-1-2, EN 60811-2-1, and IEC 60332-1 standards. It is designed for fixed installation and flexible signal transfer up to 250V in computer systems, electronic apparatus, process control units, and measurement equipment requiring high electromagnetic compatibility (EMC).
Engineered to ensure noise-free signal integrity in electrically disturbed industrial environments, the cable utilizes finely stranded copper cores wrapped within a 360-degree tinned copper wire braid. This dense braided shield intercepts external high-frequency electromagnetic interference (EMI) and prevents internal data pulses from radiating outward, safeguarding sensitive instrumentation, telemetry networks, and automated processing units against signal distortion and transmission errors.
LiYCY Cable Construction
- Conductor: Class 5 fine-stranded bare copper conductors delivering high electrical conductivity and superior physical flexibility.
- Insulation: Polyvinyl Chloride (PVC) compound engineered for precise dielectric performance and low signal loss up to +80°C.
- Bedding / Inner Layer: Concentric multi-core twisted assembly optimized for compact cross-sections and smooth cable flexibility.
- Screen / Armour: Tinned Copper Wire Braid (TCWB) providing high optical coverage for comprehensive electromagnetic compatibility (EMC) shielding.
- Outer Sheath: Specially formulated industrial-grade Polyvinyl Chloride (PVC) compound, flame retardant per IEC 60332-1.
- Core Identification: DIN 47100 standard colour coding (2-core: White, Brown; 3-core: White, Brown, Green; multi-core configurations up to 30 cores utilizing distinctive colour and tracer combinations).
- Sheath Colour: Grey.
Applications
LiYCY cables are specifically designed for low-current signal transmission, instrumentation circuits, and data communication across automated production plants, control cabinets, and commercial computing environments where electromagnetic shielding is required. Their compact overall diameter and high flexibility allow effortless routing in tight cable trays, channels, and raceways.
Typical installation environments include:
- Process Control Units & Automation Cabinets: Connecting PLCs, sensors, microprocessors, and relay racks sensitive to EMI.
- Computer Systems & Industrial Computing: Interconnecting data peripherals, server racks, and office computing networks.
- Electronic Measurement & Weighing Equipment: Transmitting low-voltage analog and digital signals without external harmonic distortion.
- Tooling Machinery & Production Control: Flexible signal links located in proximity to frequency converters and variable speed drives.
Specifications & Dimensions
The LiYCY cable portfolio encompasses extensive multi-core configurations from 2 cores up to 30 cores, with conductor cross-sections ranging from 0.14mm² up to 1.5mm² (including 0.25mm², 0.34mm², 0.5mm², 0.75mm², and 1.0mm²). Operating at a voltage rating of 250/250V with a dielectric test voltage capability of 1.2kV, the cable supports fixed installations from -30°C to +80°C and installation temperatures from -5°C to +70°C, maintaining a tight minimum bending radius of 6× overall diameter for fixed installations. All core counts, outer sheath diameters (ranging from 3.9mm up to 16.6mm), and nominal cable weights strictly adhere to VDE 0482-332-1-2 and European harmonized cable engineering tolerances.

Frequently Asked Questions
Q: What is the primary difference between LiYY and LiYCY signal cables?
A: LiYY is an unshielded flexible data cable suitable for environments free of electrical noise, whereas LiYCY incorporates an overall Tinned Copper Wire Braid (TCWB) screen that provides robust protection against electromagnetic interference (EMI).
Q: Can the LiYCY cable be used for high-voltage power transmission?
A: No, LiYCY cables have a voltage rating of 250V and are engineered specifically for low-voltage signal transmission, instrumentation, and data communication between electronic apparatus, not for primary power feeds.
