H07RN-F Cable: Powering Industries with Reliability and Flexibility
In the world of electrical cables, few are as versatile and widely used as the H07RN-F. This heavy-duty Rubber Cable is a staple across industries, from construction sites to offshore oil rigs, thanks to its durability, flexibility, and resistance to harsh conditions. But what exactly makes H07RN-F so special, and where is it most commonly used?
1. What is H07RN-F Cable?
H07RN-F is a flexible rubber-sheathed cable designed for tough environments. It complies with:
Harmonized Standard: HD 22.4 / EN 60245-4 (IEC 60245-4)
Voltage Rating: 450/750V
Temperature Range: -25°C to +60°C (flexing) / -40°C to +60°C (fixed installations)
Construction Breakdown
| Layer | Material | Function |
| Conductor | Fine-stranded copper | High flexibility (Class 5/6) |
| Insulation | EPR (Ethylene Propylene Rubber) | Heat & abrasion resistant |
| Sheath | Chloroprene Rubber (CR) | Oil, water, UV, and mechanical damage protection |
Core Variations:
Available in 1 to 5 cores (with or without earth conductor).
Common sizes: 1.5mm² to 400mm².
