H07RN-F is one of the most versatile and widely used heavy-duty flexible rubber cables in industrial and commercial applications. Known for its exceptional mechanical durability, chemical resistance, and flexibility, it has become the go-to choice for electricians, installers, and contractors in demanding environments.
This article is tailored for installers and B2B customers to understand when and why to recommend H07RN-F, what technical advantages it offers, and what other cable types might be considered as alternatives.
H07RN-F is a harmonized code cable (recognized across Europe) designed for power supply in mobile or fixed installations. It features:
Voltage rating: 450/750 V
Flexible class 5 copper conductors (EN 60228)
EPR rubber insulation (Ethylene Propylene Rubber, type EI4)
CSP or PCP sheath (Chlorosulfonated Polyethylene or Polychloroprene, type EM2)
Temperature range: –25°C to +60°C (mobile), up to 85°C (fixed)
Flame retardant: IEC 60332-1 compliant
Oil-resistant, UV-resistant, weatherproof, and robust against mechanical stress
It complies with HD22.4 / IEC 60245-4 standards.
H07RN-F is ideal for demanding environments where high flexibility and resilience are required. Common application scenarios include:
Temporary power supplies to machinery and lighting
Withstands dragging, coiling, foot traffic, and rough handling
Power tools, welding equipment, motors, pumps
Suitable for indoor and outdoor use
Power distribution for concerts, theatres, outdoor shows
Flexible for reel/unreel operations
Resistant to oil, mud, vibration, and impact
Often used in temporary or mobile systems underground
Power supply for irrigation pumps, grain dryers, crane motors
Operates reliably in damp, muddy, or corrosive conditions
| Cable Type | Voltage | Insulation / Sheath | Flexibility | Key Features | Typical Use | 
|---|---|---|---|---|---|
| H05RR-F | 300/500 V | Rubber / Rubber | High | Lightweight, general-purpose | Household appliances, indoor mobile use | 
| H07BQ-F | 450/750 V | TPU / PUR | Very high | Cut and abrasion-resistant | Robotics, moving machinery | 
| NSSHÖU | 0.6/1 kV | EPR / Rubber | High | Mining-grade, reinforced | Mining, heavy industry | 
| H05RN-F | 300/500 V | EPR / PCP | Medium | Similar to H07RN-F, but lower voltage | Light-duty industrial tools | 
| H07RN8-F | 450/750 V | Rubber / PCP | High | Submersible up to 10 m | Pumps, wastewater plants | 
Note: H07RN-F offers a good balance between flexibility, mechanical durability, and affordability — making it a “standard” heavy-duty rubber cable.
Choose H07RN-F when your project involves:
Mobile or portable equipment exposed to weather, oils, or abrasion
Installations requiring moderate to high mechanical resistance
Environments where UV and moisture resistance is essential
Systems where reliable power continuity is required even in harsh handling
It's not ideal for:
Permanent direct burial (unless specifically rated)
High-voltage applications (>0.75 kV)
Extremely lightweight or tight-bend radius needs (consider H07BQ-F instead)
H07RN-F remains one of the most installer-friendly, rugged, and versatile rubber cables available for heavy-duty use. Whether on a construction site, powering mobile tools, or delivering safe electricity to outdoor events, it provides exceptional reliability and longevity.
For projects demanding greater chemical, abrasion, or thermal resistance, cables like H07BQ-F or NSSHÖU may be better suited. However, for most general industrial and construction use cases, H07RN-F is the practical standard.
