LiYCY (TP) Cable

What is LiYCY (TP) Cable?

The LiYCY (TP) cable is a low-voltage, unarmored screened twisted-pair signal and control cable featuring fine-stranded bare copper conductors, PVC insulation, a plastic foil separator tape, an overall tinned copper wire braid (TCWB) screen, and a grey PVC outer sheath complying with DIN VDE 0812 and IEC/EN 60332-1-2 standards. It is designed for fixed and flexible interconnection up to 350V/500V in dry and humid industrial environments for control, measuring, process instrumentation, and computer signal technology.

Engineered to deliver high signal integrity in noise-prone industrial automation landscapes, this cable pairs two conductors together into short-lay twists to cancel electromagnetic coupling and prevent internal cross-talk between adjacent signal paths. Combined with a dense overall braided tinned copper screen, LiYCY (TP) prevents external electromagnetic fields (EMI) from distorting low-level analog and digital telemetry circuits, guaranteeing uninterrupted data flow across factory control rooms and machine cabinets.

LiYCY (TP) Cable Construction

• Conductor: Fine-stranded bare copper conductors delivering superior physical flexibility and low loop resistance.
• Insulation: Polyvinyl Chloride (PVC) compound engineered for dependable dielectric strength and low mutual capacitance.
• Separator: Synthetic plastic foil tape applied over the paired core assembly to facilitate smooth stripping and core flexibility.
• Screen: Tinned Copper Wire Braid (TCWB) providing a high-coverage 360-degree electromagnetic compatibility (EMC) shield.
• Outer Sheath: Specially formulated industrial-grade Polyvinyl Chloride (PVC), flame retardant per IEC/EN 60332-1-2.
• Core Identification: Color-coded pairs in compliance with DIN 47100 specifications (Pair 1: White/Brown, Pair 2: Green/Yellow, Pair 3: Grey/Pink, Pair 4: Blue/Red, etc.).
• Sheath Colour: Grey.

Applications

LiYCY (TP) cables are specifically designed for low-capacitance transmission of analog and digital signals in measurement devices, industrial process control, and electronic computing systems where high EMC protection and cross-talk attenuation are required. Their durable PVC jacket allows reliable operation across dry and humid indoor industrial environments.

Typical installation environments include:

• Process Control & Instrumentation: Interconnecting sensitive sensors, transmitters, measurement gauges, and Programmable Logic Controllers (PLCs).
• Industrial Computing & Data Transmission: Noise-free serial communication lines, RS-422/RS-485 interfaces, and SCADA monitoring networks.
• Electronic Control Panels & Switchgear: High-density internal cabinet wiring and terminal interconnects requiring flexible, paired conductor routing.
• Audio, Studio & Office Technology: Interconnection of acoustic systems, office machines, and communication consoles in humid or dry rooms.

Specifications & Dimensions

The LiYCY (TP) cable series encompasses paired multi-conductor assemblies from 2 pairs (4 cores) up to 16 pairs (32 cores), with nominal conductor cross-sections of 0.14mm², 0.25mm², 0.34mm², 0.5mm², and 0.75mm². Operating at rated voltages of 350V for 0.14mm² (800V test voltage) and 500V for cross-sections above 0.14mm² (1200V test voltage), the cable supports fixed installations from -40°C to +80°C and moved flexible applications from +5°C to +50°C. Conductor loop resistance values range from 276 Ω/km for 0.14mm² down to 50.6 Ω/km for 0.75mm², with an attenuation at 800Hz spanning from 2.3 dB/km down to 1.1 dB/km and a standard mutual capacitance of 120 nF/km. A minimum bending radius of 10× overall diameter is maintained across all sizes in accordance with DIN VDE 0812.

Frequently Asked Questions

Q: What is the primary difference between LiYCY and LiYCY (TP) cables?
A: Standard LiYCY cables feature cores laid up in concentric layers, whereas LiYCY (TP) twists conductors into distinct pairs (Twisted Pairs) prior to stranding, drastically reducing cross-talk and capacitive interference between signal channels.

Q: Why are different voltage ratings specified for 0.14mm² versus larger cross-sections?
A: In accordance with DIN VDE 0812, 0.14mm² micro-conductors utilize a thinner insulation profile suited for miniature instrumentation up to 350V, whereas cross-sections from 0.25mm² to 0.75mm² have heavier insulation rated for 500V industrial control circuits.

Q: What core color code is utilized in LiYCY (TP) cables?
A: Cores are color-coded in pairs following DIN 47100 standards (e.g., Pair 1: White/Brown, Pair 2: Green/Yellow, Pair 3: Grey/Pink, Pair 4: Blue/Red), allowing rapid, error-free field identification and termination.

Q: What payment terms does Huadong Cable accept for international industrial export orders?
A: We provide standard international commercial terms including Telegraphic Transfer (T/T) and 100% Irrevocable Letter of Credit (L/C) at sight for engineering contractors and industrial machinery OEMs.
