LiHCH Cable

What is LiHCH Cable?

The LiHCH cable is a low-voltage, unarmored and screened flexible signal and control cable featuring Class 5 flexible stranded copper conductors, LSZH insulation, a tinned copper wire braid (TCWB) screen, and a grey LSZH outer sheath complying with IEC/EN 60754-1/2 and IEC/EN 60332-1 standards. It is designed for fixed and flexible signal transmission up to 250V between electronic devices, computers, and automated process control units in installations demanding low smoke, zero halogen emissions and comprehensive EMC protection.

Engineered to protect sensitive electronic telemetry and personnel safety in enclosed environments, this cable combines an overall braided tinned copper shield that eliminates external electromagnetic interference (EMI) with advanced halogen-free thermoplastic materials. In the event of a fire, the LSZH compound releases no corrosive acid gases and produces minimal non-toxic smoke, safeguarding sensitive electronic circuitry from acid corrosion and ensuring clear evacuation corridors in public infrastructure.

LiHCH Cable Construction

• Conductor: Generally to Class 5 flexible stranded bare copper conductors delivering high mechanical flexibility and low conductor resistance.
• Insulation: Low Smoke Zero Halogen (LSZH) thermoplastic compound engineered for thermal stability up to +70°C.
• Bedding / Inner Layer: Compact multi-core bunching assembly designed for flexible routing and clean stripping.
• Screen: Tinned Copper Wire Braid (TCWB) providing a high-coverage 360-degree electromagnetic compatibility (EMC) shield.
• Outer Sheath: Low Smoke Zero Halogen (LSZH) thermoplastic compound, flame retardant per IEC/EN 60332-1 and zero halogen per IEC/EN 60754-1/2.
• Core Identification: Color-coded cores up to 25 cores (Core 1: White, Core 2: Brown, Core 3: Green, Core 4: Yellow, Core 5: Grey, Core 6: Pink, Core 7: Blue, Core 8: Red, etc.).
• Sheath Colour: Grey.

Applications

LiHCH cables are specifically designed for low-current signal interconnects, data acquisition, and process automation in public buildings, industrial facilities, and data centers where fire hazards and electromagnetic interference must be strictly controlled. Their halogen-free design makes them mandatory in densely populated or enclosed spaces.

Typical installation environments include:

• Public Buildings & Commercial Infrastructure: Airports, hospitals, railway stations, and shopping complexes requiring LSZH fire safety compliance.
• Industrial Process Control & Automation: Signal connections between Programmable Logic Controllers (PLCs), distributed control systems (DCS), and field sensors.
• Computer Systems & Data Centers: Low-voltage communication lines, server racks, and peripheral telemetry requiring high EMC suppression.
• Electronic Control Cabinets & Switchboards: Compact instrumentation wiring and terminal boards in dry and damp indoor environments.

Frequently Asked Questions

Q: What is the primary difference between LiYCY and LiHCH cables?
A: While both cables feature Class 5 conductors and an overall TCWB screen for EMC protection, LiYCY uses PVC insulation and sheathing, whereas LiHCH utilizes Low Smoke Zero Halogen (LSZH) materials that emit no toxic halogens or corrosive acidic fumes during a fire.

Q: Why is the LiHCH cable rated at 250V instead of 300/500V?
A: LiHCH is specifically engineered for sensitive low-voltage electronic signal, measuring, and computing circuits where compact dimensions and fine strand diameters are prioritized over high-voltage power transmission.

Q: How does the TCWB braid improve performance in automated control rooms?
A: The high-density Tinned Copper Wire Braid (TCWB) forms a low-resistance conductive envelope around the cores, reflecting and dissipating high-frequency electromagnetic noise from neighboring power lines, inverters, and heavy machinery.

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