In this comprehensive guide, we’ll explore everything you need to know about H07RN-F cables, from technical specifications to real-world applications.
What is H07RN-F Cable?
H07RN-F is a harmonized flexible rubber-sheathed cable designed for heavy-duty applications where standard PVC cables would fail. The designation “H07RN-F” follows European harmonization standards, where:
- “H” indicates harmonized cable
- “07” refers to the voltage rating (450/750V)
- “R” stands for rubber insulation
- “N” indicates rubber or thermoplastic elastomer sheathing resistant to oil and weather
- “F” denotes high flexibility

How to Select the Right H07RN-F Cable
Choosing the appropriate H07RN-F cable requires consideration of several factors:
- Determine Required Current Capacity: Calculate the expected load and select conductor size accordingly
- Assess Environmental Conditions: Consider temperature extremes, exposure to oils/chemicals, UV exposure
- Number of Cores Needed: Match core count to your equipment requirements (2-core, 3-core, 4-core, or 5-core)
- Verify Certification Requirements: Ensure the cable meets regulatory requirements for your region and application
- Consider Mechanical Stress: For highly dynamic applications, verify the cable’s flex rating is adequate
H07RN-F vs. Alternative Flexible Cables
| Feature | H07RN-F | H05RN-F | PVC Flexible Cables |
|---|---|---|---|
| Voltage Rating | 450/750V | 300/500V | Typically 300/500V |
| Temperature Range | -40°C to +90°C | -25°C to +80°C | -5°C to +70°C |
| Oil Resistance | Excellent | Good | Poor to Fair |
| UV Resistance | Excellent | Good | Fair to Poor |
| Flexibility | Excellent | Excellent | Good |

Maintenance & Service Life
With proper installation and use within specifications, H07RN-F cables typically provide 10-15 years of reliable service. To maximize lifespan:
- Periodically inspect for physical damage, especially at connection points
- Check for signs of overheating (discoloration, hardening of rubber)
- Replace cables showing cracks, excessive wear, or damaged insulation
- Store spare cable in cool, dry conditions away from direct sunlight
Frequently Asked Questions
Q: Can H07RN-F cable be used permanently outdoors? A: Yes, H07RN-F is specifically designed for outdoor use with excellent UV and weather resistance. It’s suitable for permanent outdoor installations.
Q: Is H07RN-F cable suitable for direct burial? A: While H07RN-F has good water resistance, it’s not specifically designed for direct burial. It should be installed in conduit or cable ducting when buried underground.
Q: How does H07RN-F compare to SOOW cable? A: H07RN-F is the European harmonized equivalent to North American SOOW cable. Both offer similar performance characteristics with rubber insulation and oil-resistant jackets.
Q: What’s the difference between H07RN-F and H05RN-F? A: H07RN-F is rated for higher voltage (450/750V vs 300/500V) and generally has better temperature resistance and mechanical properties than H05RN-F.
Q: Can H07RN-F cable be used in food processing environments? A: Standard H07RN-F is not certified for direct food contact. Special variants with food-grade rubber compounds are available for food processing applications.
