H07RN-F Heavy Duty Rubber Flexible Cable | For Connecting Machines & Industrial Equipment

Product Overview

The H07RN-F is a heavy-duty rubber flexible cable specifically designed for connecting industrial machinery, power tools, and mobile equipment in demanding environments . Known as the industry standard for rugged connectivity, this cable combines fine-stranded copper conductors with durable rubber insulation and sheath, delivering exceptional flexibility, mechanical strength, and resistance to oil, weather, and mechanical stress .

The "H07RN-F" designation provides key information at a glance:

• H – Harmonized type (European standard)

• 07 – 450/750V rated voltage

• R – Natural/EPDM rubber insulation

• N – Polychloroprene (neoprene) rubber sheath

• F – Fine-stranded copper conductor (Class 5 for flexibility)

Key Applications

• Connecting industrial machinery and production equipment

• Power supply for portable tools and mobile units

• Temporary power distribution on construction sites

• Agricultural equipment and farm machinery

• Marine and offshore applications (water-resistant)

• Wind turbine cable connections

Frequently Asked Questions (FAQ)

Q: What does H07RN-F stand for?

A: H07RN-F is the harmonized European designation: H = Harmonized type, 07 = 450/750V rating, R = Natural/EPDM rubber insulation, N = Neoprene (polychloroprene) rubber sheath, F = Fine-stranded flexible conductor (Class 5) .

Q: What is the difference between H07RN-F and ordinary rubber cable?

A: H07RN-F is a harmonized standard cable with guaranteed performance characteristics (voltage rating, temperature rating, oil resistance, flame retardancy). It carries HAR approval, ensuring compliance across European markets .

Q: Can this cable be used outdoors?

A: Yes. The neoprene rubber sheath provides excellent resistance to UV radiation, ozone, weathering, and wide temperature ranges, making H07RN-F ideal for permanent outdoor installation .

Q: Is H07RN-F oil resistant?

A: Yes. The sheath material (neoprene/CR rubber) is specifically formulated for oil resistance, complying with EN 60811-404 testing .

Q: Can this cable be submerged in water?

A: Standard H07RN-F is suitable for outdoor and damp locations but not designed for continuous submersion. Premium versions (AD8 rated) are suitable for submersion up to 100 meters .

Q: Is this cable flame retardant?

A: Yes. H07RN-F complies with IEC 60332-1-2 for single vertical cable flame retardancy. It will self-extinguish when the ignition source is removed .

Q: What is the minimum bending radius for machine connection?

A: For flexible applications (connecting moving machines), the minimum bending radius is 6 × overall diameter . For fixed installations, 4 × overall diameter is acceptable .

Q: Is the cable suitable for wind turbine applications?

A: Yes, premium torsion-resistant versions are available specifically for wind turbine cable loops, rated for -40°C to +90°C with +/-150° per meter torsion

Quality Assurance

All H07RN-F cables are manufactured under strict quality control procedures:

• 100% electrical testing – Conductor resistance, insulation resistance, high voltage testing
• Raw material traceability – Full batch traceability for copper and rubber compounds
• In-process inspection – Dimensional and visual checks throughout production
• Factory certification – ISO 9001:2015 certified manufacturing facility
• HAR certification – Independent verification of harmonized standard compliance

Third-Party Inspection: We welcome independent third-party inspectors (SGS, BV, TUV, etc.) to witness manufacturing, testing, and packaging before shipment. Inspection costs are typically borne by the buyer unless otherwise negotiated.
