When selecting the right cable for industrial, outdoor, or heavy-duty applications, understanding cable codes and specifications is essential. One common question we encounter is: What does the “RN” in H07RN-F stand for? Moreover, how does H07RN-F differ from the more common RVV cable?
In this article, we break down the meaning behind the H07RN-F coding and provide a clear comparison to help you choose the best flexible cable for your project.
H07RN-F: Decoding the “RN”
H07RN-F is a European harmonized heavy-duty rubber cable, widely used in demanding environments. Each part of its name carries specific information:
- H: European harmonized standard (HAR)
- 07: Voltage rating of 450/750V
- R: Rubber insulation, specifically EPR (Ethylene Propylene Rubber)
- N: Neoprene (PCP/CR) sheath, a type of chloroprene rubber
- F: Fine-wire stranded copper conductor
So, what does “RN” mean?
The combination of R and N indicates:
- R (Rubber/EPR insulation): Provides excellent temperature resistance, flexibility, and durability.
- N (Neoprene sheath): Offers strong resistance to oil, weathering, abrasion, and UV exposure.
Together, RN stands for a cable with rubber insulation + chloroprene rubber sheath, making it exceptionally resistant to oil, abrasion, aging, and suitable for outdoor use.
H07RN-F vs. RVV: Key Differences
While both H07RN-F and RVV are flexible cables, they are designed for different conditions. Here’s a detailed comparison:

Which One Should You Choose?
- Choose H07RN-F if you need a cable for harsh conditions: outdoors, exposure to oils, chemicals, UV light, or constant movement. It’s the go‑to for construction, mining, events, and industrial machinery.
- Choose RVV if your application is indoors, in dry areas, with minimal exposure to oils or sunlight. It’s a cost‑effective solution for light power and control wiring.
Conclusion
Understanding cable codes like H07RN-F helps you make informed decisions for safety and performance. The RN marking guarantees robust rubber insulation and a neoprene sheath—ideal for tough, outdoor, and oil‑prone settings. In contrast, RVV offers reliable indoor flexibility at a lower cost.
