When sourcing industrial cables, one simple question often determines compliance, safety, and long-term reliability: Is this cable halogen free?
H07RN-F is one of the most widely used flexible rubber cables in the world, trusted for tough environments and demanding applications. Yet many buyers-especially those involved in international projects-still ask: Is H07RN-F halogen free?
The answer is not just a technical detail. It directly affects fire safety, regulatory compliance, and correct cable selection. In this article, we'll clarify the facts, compare alternatives, and help you choose the right solution with confidence.
What Is H07RN-F Cable?
H07RN-F is a harmonized flexible rubber-sheathed power cable defined by European standards such as VDE, HAR, and EN 50525.
Key characteristics include:
- Rated voltage: 450/750V
- Fine-stranded copper conductor for flexibility
- Rubber insulation and heavy-duty rubber outer sheath
- Excellent resistance to oil, abrasion, moisture, UV, and mechanical stress
Typical applications:
- Construction sites
- Industrial machinery
- Mobile equipment
- Ports, mining, and outdoor installations
H07RN-F is designed for performance and durability in harsh conditions, making it a favorite across industrial sectors.
What Is a Halogen Free (LSZH) Cable?
A Halogen Free cable, often referred to as LSZH (Low Smoke Zero Halogen), is manufactured without halogen elements such as chlorine, fluorine, bromine, or iodine.
Why does this matter?
- When halogen-containing cables burn, they release toxic and corrosive gases
- These gases can harm people, damage equipment, and reduce visibility during fires
Common standards for halogen-free cables:
- IEC 60754-1 / 60754-2 (acid gas emission)
- IEC 61034 (smoke density)
Halogen-free cables are widely required in public buildings, tunnels, railways, data centers, and environmentally sensitive projects.
Is H07RN-F a Halogen Free Cable?
No - standard H07RN-F cable is NOT halogen free.
The reason is simple:
- H07RN-F uses rubber compounds (such as EPR insulation and PCP or similar rubber sheaths)
- These materials are optimized for mechanical strength and flexibility, not for halogen-free fire performance
While H07RN-F performs excellently in demanding environments, it does not meet LSZH or halogen-free requirements under IEC standards.
H07RN-F vs. Halogen Free (LSZH) Cables
| Feature | H07RN-F Cable | Halogen Free (LSZH) Cable |
|---|---|---|
| Halogen content | Contains halogens | Halogen free |
| Smoke & toxicity | Higher smoke, corrosive gases | Low smoke, non-corrosive |
| Flexibility | Excellent | Good to moderate |
| Mechanical strength | Very high | Moderate |
| Oil & abrasion resistance | Excellent | Limited (model-dependent) |
| Typical use | Industrial & outdoor | Public & safety-critical areas |
| Cost | Competitive | Usually higher |
H07RN-F is not "better" or "worse" - it is simply designed for different priorities.
Where Is H07RN-F the Right Choice?
H07RN-F is ideal when mechanical performance and durability are more critical than halogen-free requirements.
Recommended applications include:
- Construction and temporary power supply
- Heavy-duty industrial equipment
- Outdoor installations exposed to weather
- Mobile tools and extension leads
- Oil-contaminated or high-wear environments
If no regulation explicitly requires LSZH, H07RN-F often provides the best balance of performance and cost.
What If Your Project Requires Halogen Free Cables?
For projects that must comply with LSZH or fire safety regulations, alternative solutions are available:
- Halogen-free flexible power cables (LSZH compounds)
- CPR-compliant cables for European construction projects
- Custom-designed LSZH cables with enhanced flexibility
A professional supplier can help you select or customize the correct halogen-free alternative based on voltage, flexibility, and installation conditions.
