TEBAOFLEX H07RN-F 450/750V Heavy-Duty Flexible Rubber Cable is manufactured in accordance with harmonized European standard EN 50525-2-21 (DIN VDE 0285-525-2-21 / IEC 60245-4 66) for medium-to-high mechanical stress in dry, damp, wet, and outdoor industrial service. Built with IEC 60228 Class 5 fine-stranded copper conductors, cross-linked EI4 EPR core insulation, and a rugged oil-, ozone-, and flame-resistant black EM2 polychloroprene (PCP) rubber outer sheath, it supports both 450/750 V portable feeders and 0.6/1 kV fixed protected installations.
1. Industrial Application Scope & Harmonized H07 Rubber Family Comparison
Where PVC site cables crack in winter cold or split under workshop impact and oil splash, H07RN-F remains supple and abrasion-resistant across repeated coiling, dragging, and outdoor weather exposure:
- Rental Generators, Load Banks & Temporary Site Power: Single-core (
1×35to1×630 mm²with Powerlock/camlock terminations) and 5-core three-phase distribution feeders (5G2.5to5G95 mm²) for construction sites, shipyards, and outdoor events. - Industrial Machinery, Workshops & Agricultural Equipment: Flexible power supply leads for mobile compressors, welding sets, woodworking/metalworking machines, heating plates, and portable inspection lamps.
- Fixed Protected Crane, Hoist & Switchgear Wiring (Up to 0.6/1 kV): Vibration-resistant motor and busbar jumpers in conduits, plaster, or enclosed crane girders per HD 516 / DIN VDE 0298-300.

2. Concentric 4-Layer Cable Construction (EN 50525-2-21)
Matching the multi-core cross-section photograph above, TEBAOFLEX H07RN-F is built from electrolytic Class 5 copper outward with vulcanized thermoset elastomers that will not melt under overload or weld-splatter contact:
G = including Green/Yellow protective earth, e.g., 5G: Green/Yellow, Blue, Brown, Black, Grey; X = without Green/Yellow); 6 cores and above use black cores with sequential white numbers plus Green/Yellow PE, laid up with central textile/elastomer filler where required for circularity.3.

5. Frequently Asked Engineering Questions & Custom RFQ
What do the harmonized designation codes in H07RN-F stand for?
Under CENELEC HD 361 / EN 50525 coding, H denotes a harmonized standard, 07 specifies a 450/750 V nominal rating, R indicates cross-linked EPR rubber core insulation (EI4), N denotes a heavy-duty polychloroprene (PCP, EM2) outer sheath, and -F specifies an IEC 60228 Class 5 flexible fine-stranded copper conductor.
Can H07RN-F cable be operated at 0.6/1 kV (600/1000 V)?
Portable and free-flexing H07RN-F installations are rated 450/750 V AC. Under HD 516 / DIN VDE 0298-300 rules, H07RN-F may be operated up to 0.6/1 kV AC when installed in fixed, mechanically protected routing such as conduits, switchgear cabinets, or crane hoist motors.
What is the difference between H07RN-F and H07RN8-F rubber cables?
H07RN-F covers indoor, outdoor, damp, and splash worksite duty, whereas H07RN8-F uses an AD8 water-resistant compound tested per EN 50525-2-21 for continuous shallow-water immersion up to 10 m on submersible pumps.
Are TEBAOFLEX H07RN-F conductors bare copper or tinned copper?
Standard H07RN-F uses IEC 60228 Class 5 fine-stranded annealed bare copper conductors, matching the cross-section photo above. Class 5 tinned copper conductors can be manufactured to order for marine shore-power or corrosive chemical plants.
What is the minimum bending radius for H07RN-F?
Per HD 516 / DIN VDE 0298-300, minimum bending radius is 4 × D for fixed protected installations and 6 × D to 8 × D for flexible mobile handling (where D is finished cable outer diameter).
What sizes and core counts can TEBAOFLEX supply in H07RN-F?
TEBAOFLEX supplies single-core 1×1.5 mm² up to 1×630 mm², 2-core to 5-core power cables (3G1.5 to 5G300 mm²), and multi-core control builds from 7G1.5 up to 24G2.5 mm². Submit your core count, cross-section, drum length, and destination port for quotation.
