Choosing the correct flexible cable is critical for the safety, efficiency, and longevity of your electrical installations, especially in demanding environments. Two of the most commonly specified cables for industrial and commercial applications are the H07RN-F and H07ZZ-F. While they may seem similar at first glance, key differences determine their ideal use cases. This guide from JZD Cable will provide a detailed comparison to help you make an informed decision.
What is H07RN-F Cable?
The H07RN-F cable is a heavy-duty, synthetic rubber-sheathed flexible cable designed for extreme conditions. Its construction prioritizes durability and resilience.
- Standards: It complies with harmonized European standard HD 22.12 S2 and carries the CE marking.
- Conductor: Fine stranded bare copper for excellent flexibility (Class 5).
- Insulation: Synthetic Rubber (Ethylene Propylene Rubber – EPR).
- Sheath/Jacket: Heavy-duty, oil-resistant, and weather-resistant Chloroprene Rubber (Neoprene).
- Key Properties: Highly resistant to abrasion, oil, ozone, and weathering. It remains flexible in a wide temperature range.
- Typical Applications: Ideal for outdoor use, construction sites, workshops, industrial machinery, temporary power supplies, and areas exposed to mechanical stress, oils, and harsh weather.
What is H07ZZ-F Cable?
The H07ZZ-F cable is a lightweight, synthetic elastomer-sheathed flexible cable. It offers a balance of good performance and cost-effectiveness for less extreme conditions.
- Standards: It complies with harmonized European standard HD 22.13 S2 and is CE marked.
- Conductor: Fine stranded bare copper for flexibility (Class 5).
- Insulation: Polyvinyl Chloride (PVC) or similar thermoplastic elastomer.
- Sheath/Jacket: Lightweight, oil-resistant synthetic elastomer.
- Key Properties: Resistant to low concentrations of oils, fats, and water. It is flexible, lightweight, and easier to handle than H07RN-F.
- Typical Applications: Perfect for indoor use, light industrial tools, control panels, appliance leads, workshop equipment, and situations where the cable is not exposed to constant mechanical abuse or severe outdoor weathering.
Key Similarities Between H07RN-F and H07ZZ-F Cables
Despite their differences, these cables share important common ground:
- Harmonized Standards: Both are standardized under European HD norms, ensuring a consistent level of safety and performance.
- Voltage Rating: Rated at 450/750V.
- Conductor: Both use fine-stranded copper conductors (Class 5), making them highly flexible.
- Core Identification: Typically use color coding (e.g., brown, blue, green/yellow) for easy identification of live, neutral, and earth conductors.
- Flexibility: Designed for applications requiring movement or frequent repositioning.
Key Differences Between H07RN-F and H07ZZ-F Cables (With Comparison Table)
The primary distinctions lie in the jacket material and the resulting performance characteristics, which directly impact price and application suitability.

Which Cable Should You Choose? Selection Advice
Your choice should be driven by the operating environment and the required durability.
Choose H07RN-F Cable if:
- Your application is primarily outdoors or exposed to the elements.
- The cable will face abrasion, cuts, crushing, or constant mechanical stress.
- It will be exposed to oils, fuels, or chemicals.
- You need maximum durability for heavy industrial, construction, or mining equipment.
- The installation requires the highest level of toughness and long service life, justifying the higher initial investment.
Choose H07ZZ-F Cable if:
- Your application is primarily indoors or in sheltered areas.
- You need a reliable, flexible cable for light industrial tools, machinery, or control systems.
- The environment is clean with only occasional exposure to water or low-concentration oils.
- Cost is a significant factor, and the extreme durability of H07RN-F is not required.
- You prioritize lightweight and easy handling for installation.
