H07RN-F 2.5 mm² Heavy Duty Rubber Cable – Flexible, Robust & Weatherproof for Professional Use
The H07RN-F 2.5 mm² is a heavy-duty, harmonized flexible rubber cable according to EN 50525-2-21 (formerly VDE 0282-4 / HD 22.4). It features excellent flexibility, high mechanical strength, and superior resistance to oil, grease, UV radiation, ozone, and weathering. Designed for medium mechanical stress, this cable is the preferred choice for professional electricians, electrical contractors, construction companies, renovation firms, industrial plants, van conversions, camper builds, and research facilities.
Key Features and Benefits of H07RN-F 2.5 mm² Rubber Cable
This heavy-duty rubber cable has finely stranded bare copper conductors (Class 5), EPR (ethylene propylene rubber) insulation, and a black neoprene (PCP) outer sheath. Its harmonized design (HAR) ensures full compliance with European safety standards, making it suitable for dry, damp, wet rooms, and outdoor applications.
- High flexibility and excellent vibration resistance
- Oil, grease, UV, ozone, and weather resistant
- Flame retardant according to EN 60332-1-2
- Temperature range: -25°C to +60°C (flexing) / up to +80–90°C (fixed, depending on manufacturer)
- Short-circuit temperature up to +200°C (max. 5 s)
Applications of H07RN-F 2.5 mm² – Ideal for Demanding Professional Environments
The H07RN-F 2.5 mm² flexible rubber cable excels wherever high flexibility and durability under tough conditions are required. Common professional applications include:
Construction Sites and Renovation Projects
Perfect for construction companies and renovation contractors. Use it for powering power tools, temporary lighting, mobile distribution boards, and construction machinery. The cable withstands dirt, moisture, and mechanical abrasion on building sites.
Industrial and Commercial Installations
Reliable connection for motors, pumps, machines, and portable equipment in factories and workshops. Its strong oil and chemical resistance makes it ideal for demanding industrial environments.
Van Conversion and Camper Van Builds
Highly recommended for van life and camper conversions. The flexible design ensures vibration-proof and weather-resistant wiring for onboard electrical systems, solar setups, inverters, and chargers – even under extreme temperature fluctuations.
Research Facilities and Laboratories
Excellent for mobile test setups, experimental rigs, and temporary power supplies. The superior flexibility reduces downtime when equipment is frequently moved or reconfigured.
Additional Professional Applications
- Agricultural equipment and outdoor machinery
- Events, festivals, and mobile generators
- Portable tools, welders, and submersible pumps (with appropriate protection)
- Fixed surface installations on plaster or machinery (not for direct burial without protection)

Frequently Asked Questions (FAQ) about H07RN-F 2.5 mm² Rubber Cable
What does the designation H07RN-F mean?
H = Harmonized standard, 07 = Rated voltage 450/750 V, R = EPR insulation, N = Neoprene (PCP) sheath, F = Flexible conductor (Class 5). It is a heavy-duty rubber cable for medium mechanical stress.
What current carrying capacity does the 2.5 mm² version have?
Depending on installation method and ambient temperature (at 30°C), it typically supports 20–36 A. Refer to current national standards or VDE tables for exact values. Suitable for tools, motors, and equipment up to approx. 16–25 kW at 400 V.
Can the H07RN-F cable be used permanently outdoors?
Yes. It is UV, ozone, and weather resistant and approved for outdoor use. It is not suitable for unprotected direct burial in the ground.
Is H07RN-F suitable for van conversions and camper builds?
Absolutely. Its high flexibility and vibration resistance make it an excellent choice for vehicle electrical systems, solar installations, and mobile power supplies.
How does it compare to NYM-J or H07V-K cables?
H07RN-F is significantly more flexible, mechanically robust, and better suited for moving applications and wet/outdoor environments. NYM-J is mainly for fixed indoor installations, while H07V-K is less flexible and less weatherproof.
Is the rubber cable flame retardant?
Yes, it meets the flame retardancy test according to EN 60332-1-2 and is approved for commercial and industrial use.
Can it be used in potentially explosive atmospheres?
Yes, when installed with appropriate protective measures according to EN 60079 / ATEX regulations.
Why choose H07RN-F 2.5 mm² for professional projects?
It combines outstanding flexibility with professional-grade durability, meets all current European standards, and minimizes downtime in daily heavy-duty use – exactly what electrical contractors, construction firms, and industrial companies need.
