LSZH Signal Control Cables | Halogen-Free and Fire-Safe Industrial Solutions by ETK Kablo

ETK Kablo’s LSZH (Low Smoke Zero Halogen) signal control cables are engineered for environments where fire safety, human protection, and environmental compliance are critical. These cables deliver reliable signal transmission and control performance while preventing the release of toxic halogen gases and dense smoke during combustion. Designed for public buildings, transportation systems, and enclosed industrial facilities, LSZH signal control cables ensure safety without compromising electrical performance.

Construction and Material Features

Each ETK Kablo LSZH signal control cable is constructed with fine-stranded Class 5 copper conductors according to IEC 60228, providing high flexibility and mechanical strength. The cores are insulated with a halogen-free, flame-retardant compound engineered for low smoke emission. Conductors are twisted into multi-core configurations with consistent lay lengths, ensuring stable signal transmission and minimal crosstalk. The halogen-free outer sheath, typically in grey or black, offers durability and resistance to oils, chemicals, and mechanical stress, making these cables suitable for dynamic installations and confined spaces.

Electrical and Mechanical Properties

ETK Kablo’s LSZH signal control cables are designed for a nominal voltage of 300/500V and function effectively across temperature ranges from -40°C (fixed) to +70°C (flexing). They provide excellent insulation resistance, dielectric strength, and signal integrity even over long distances. Shielded variants, featuring aluminum-polyester foil or tinned copper braid, enhance electromagnetic compatibility (EMC) in environments exposed to strong interference — ideal for automation panels, control rooms, and machinery operating near high-power circuits.

Compliance with International Standards

All ETK Kablo LSZH signal control cables are manufactured and tested in accordance with global safety and quality standards, including:

• IEC/EN 60332-1-2 – Flame retardancy
• IEC/EN 60754-1/2 – Halogen-free composition and low toxicity
• IEC/EN 61034-1/2 – Low smoke density during combustion

Additionally, the cables comply with RoHS and REACH directives, ensuring environmental safety and suitability for export to regions with strict regulatory requirements.

Applications of LSZH Signal Control Cables

ETK Kablo’s halogen-free signal control cables are extensively used across safety-critical sectors, including:

• Public infrastructure: Hospitals, schools, airports, and high-rise buildings
• Transportation systems: Metro tunnels, railway networks, and marine vessels
• Industrial automation: Control panels, PLC systems, and process automation
• Data centers and power facilities: Areas requiring uninterrupted signal reliability and minimal smoke generation

These cables ensure continuous operation and reduced fire risk, protecting both people and equipment in emergency conditions.

LSZH Signal Control Cables — Frequently Asked Questions

What is LSZH cable?

LSZH (Low Smoke Zero Halogen) cable uses halogen-free compounds for insulation and/or sheath so that, in a fire, it emits very little smoke and no corrosive halogen gases. It’s designed to improve visibility and reduce toxic exposure during evacuation while protecting sensitive equipment.

Where should LSZH cable be used?

Use LSZH in enclosed or people-dense spaces where fire safety is critical: hospitals, schools, airports, data centers, high-rise buildings, tunnels/metro and transport hubs, and control rooms. It’s also preferred around mission-critical electronics that could be damaged by corrosive smoke.

What is the difference between LSOH and LSZH cable?

None in practice. LSOH (Low Smoke, Zero Halogen) and LSZH are used interchangeably. Both indicate halogen-free materials with low smoke emission during fire. Always check compliance to relevant tests (e.g., IEC/EN 60754, 61034, 60332).

Is LSZH better than PVC?

LSZH is better for fire safety (low smoke, no corrosive halogens). PVC is usually more cost-effective, flexible, and adequate for low-risk areas. Choose based on building codes, occupancy, and environmental risk; specify LSZH for public or enclosed spaces.

Is LSZH the same as XLPE?

No. LSZH describes a halogen-free, low-smoke material family used for sheath/insulation. XLPE (cross-linked polyethylene) is a specific insulation polymer known for higher temperature ratings and dielectric strength. A cable can be XLPE-insulated and still have an LSZH outer sheath.
