What is LiHH Cable?
The LiHH cable is a low-voltage, unarmored and unscreened flexible electronic control cable featuring Class 5 fine-stranded bare copper conductors, LSZH insulation, and a grey LSZH outer sheath complying with IEC/EN 60754-1/2, IEC/EN 61034-1/2, and IEC/EN 60332-1-2 standards. It is designed for fixed installation, flexible connection, and signal transfer up to 250/250V across electronic devices, measuring apparatus, computer networks, and process control units.
Engineered to prioritize human life safety and sensitive hardware protection in modern commercial and industrial environments, the cable utilizes advanced halogen-free thermoplastic polymers for both core insulation and the outer jacket. In the event of fire exposure, the LSZH formulation emits zero toxic halogen acid gases and virtually transparent smoke, preventing corrosive damage to delicate electronic circuits while keeping escape routes clear in public buildings, data facilities, and automated plant rooms.
LiHH Cable Construction
- Conductor: Generally to Class 5 fine-stranded bare copper conductors per IEC/EN 60228 delivering superior flexibility and dependable termination.
- Insulation: Low Smoke Zero Halogen (LSZH) thermoplastic compound engineered for stable electrical insulation up to +70°C.
- Bedding / Inner Layer: Compact multi-core bunching geometry designed for smooth, flexible routing and clean stripping.
- Screen / Armour: Unscreened / Non-armored configuration optimized for minimal cable diameter and lightweight installation.
- Outer Sheath: Low Smoke Zero Halogen (LSZH) thermoplastic compound, flame retardant per IEC/EN 60332-1-2 and halogen-free per IEC/EN 60754-1/2.
- Core Identification: Color-coded cores conforming to DIN 47100 standards 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
LiHH cables are specifically developed for signal interconnection, measurement telemetry, and process automation in public buildings, industrial manufacturing centers, and communication systems where strict fire safety and halogen-free properties are mandatory. Their robust LSZH jacket permits safe indoor installation in both dry and wet rooms as well as under-plaster architectural applications.
Typical installation environments include:
- Public Infrastructure & Commercial Facilities: Airports, hospitals, educational institutions, and high-rise commercial complexes requiring LSZH fire compliance.
- Electronic Measurement & Process Control: Interconnecting laboratory instrumentation, sensors, Programmable Logic Controllers (PLCs), and relay modules.
- Computer Systems & Data Centers: Low-current signal routing, telemetry racks, and peripheral interconnect lines requiring low smoke hazard profiles.
- Architectural & Cabinet Wiring: Under-plaster building automation routes and high-density control cabinet terminal boards.
Specifications & Dimensions
The LiHH cable portfolio covers multi-core configurations from 2 cores up to 25 cores, with nominal conductor cross-sectional areas spanning 0.14mm², 0.25mm², 0.34mm², 0.5mm², 0.75mm², 1.0mm², and 1.5mm². Operating at an engineered rated voltage of 250/250V, the cable supports fixed ambient temperatures from -40°C to +70°C and flexed installation from +5°C to +70°C, maintaining a tight minimum bending radius of 7.5× overall diameter. All conductor bunching profiles, overall cable outer diameters, and nominal weights strictly conform to IEC/EN 60754, IEC/EN 61034, and European harmonized cable manufacturing standards.

Frequently Asked Questions
Q: What is the primary difference between LiHH and LiHCH cables?
A: LiHH is an unscreened (unshielded) flexible LSZH control cable designed for minimal weight and compact dimensions, whereas LiHCH incorporates an overall Tinned Copper Wire Braid (TCWB) screen to prevent electromagnetic interference (EMC) in electrically noisy areas.
Q: Why is Low Smoke Zero Halogen (LSZH) insulation critical for indoor electronic installations?
A: LSZH compounds emit virtually non-toxic smoke and zero acidic halogen fumes when exposed to fire, preventing toxic inhalation hazards for occupants and protecting expensive computing hardware from acid gas corrosion.
Q: Can LiHH cable be installed under plaster in building projects?
A: Yes, LiHH is certified for indoor installation in dry and wet rooms, including direct installation under plaster and within building conduit channels for building automation systems.
Q: What are Huadong Cable’s standard production and dispatch lead times for international orders?
A: Our standard production and dispatch lead time is typically 15-25 working days, depending on the required core count, conductor cross-section, and total project quantity.
