H07RN-F is a kind of cable designation defined within the IEC 60245 standard. The code itself is meaningful:
- H: Harmonized (European) cable.
- 07: Voltage rating code (450/750V).
- R: Rubber insulation (specifically, Ethylene Propylene Rubber – EPR).
- N: Neoprene (Polychloroprene) sheath.
- F: Fine-wire stranded conductors (for high flexibility).
The purpose of naming H07RN-F is to identify a cable with a very specific set of properties for heavy-duty industrial use. When you buy an “H07RN-F cable,” you are buying a cable built to the exact recipe outlined for the H07RN-F type within the IEC 60245 rulebook.
Key Features of H07RN-F:
- Voltage: 450/750V.
- Temperature Range: -40°C to +60°C (flexible down to -25°C).
- Core Colors: Brown, Black, Grey, Blue, Green/Yellow (for 3, 4, or 5 cores).
- Sheath Color: Typically black or orange.
- Properties: Highly flexible, weather-resistant, UV-resistant, oil-resistant, and very tough. It’s the most common cable for industrial extension leads, construction sites, and outdoor equipment.
