Halogen-free mains cable

Halogen-free power cables (LSZH): less smoke, more protection for people, technology and infrastructure

In buildings with lots of people or sensitive electronics, every minute counts in the event of a fire: LSZH stands for "Low Smoke Zero Halogen" – materials that typically produce less smoke and less corrosive halogen gases than traditional PVC solutions.

Why halogen-free LSZH power cables are often the better choice in projects

Halogen-free sheathing and insulation materials are used where, in the event of a fire, visibility, orientation and protection of technology are more important than just the price per cable.

Typical advantages of LSZH in B2B applications

  • Less smoke → better orientation and escape routes (typical test context: EN/IEC 61034)
  • Less corrosive halogen gases → lower risk of corrosion on metal and electronics (typical test context: IEC 60754)
  • Suitable for large numbers of people → e.g. schools, hospitals, public buildings
  • Suitable for expensive technology → e.g. data centres, server rooms, industrial IT

Important: "Halogen-free/LSZH" does not mean "fireproof". Even LSZH cables can release harmful gases such as CO in the event of a fire. The main advantage is lower smoke emission and fewer corrosive halogen acids – depending on the material and test context.

How can you quickly select the right LSZH power cable?

Three points are usually sufficient for a quick pre-selection: operating environment, protection requirements for electronics and internal specifications. You can then jump directly to the appropriate category.

Practical tip: Pay attention to material specifications such as H05Z1Z1-F (example) and approvals such as VDE or ENEC if these are required for the project.

Schuko (CEE 7/7) to IEC C13 and LSZH cold device extensions C13 to C14 are frequently chosen in everyday B2B use – typical solutions for IT workstations, server technology and structured infrastructure.

Schuko to C13 – 1.8 m

Typical LSZH design for standard IT and workplace technology with professional requirements.

To the product
Schuko to C13 – 3 m / 5 m

Suitable when additional length is required in racks, under tables or in technical areas.

FAQ: Halogen-free and LSZH explained briefly

What does "halogen-free" mean in relation to cables?

"Halogen-free" refers to sheathing and insulation materials without halogen-containing components. In the event of a fire, this typically results in fewer acidic and corrosive halogen gases (typical test context: IEC 60754).

What does "low smoke" mean in LSZH?

"Low smoke" describes reduced smoke development, e.g. assessed via smoke density and light transmission in test procedures (typical test context: EN/IEC 61034).

Is LSZH automatically flame-retardant?

Not automatically. The fire behaviour depends on the overall cable structure. Different tests are used for flame propagation depending on the application (typical test context: IEC 60332).

What information is needed for a quick recommendation?

For a quick pre-selection, the plug type and coupling (e.g. Schuko to C13 or C13 to C14), length, cross-section or power requirement and the application environment are particularly helpful.

This page is intended for technical guidance. Requirements may vary depending on the industry, building standard and target market.

LSZH power cables for projects, rollouts and series

Halogen-free DINIC power cables (LSZH) are particularly useful when safety, technical protection and clear specifications are paramount. If required, we can assist you in selecting the right cable based on application, length, cross-section and approvals.
