Driver : Tornered copper soul without oxygen, ensuring good conductivity and long -term oxidation resistance.
Standards : In accordance with certifications in 50525-2-21 and IEC 60245-4, Ideal for applications requiring frequent movements.
1.2 Cable H05VV-F
Insulation and sheath : A PVC (polyvinyl chloride), Economic and fireproof material, but which becomes rigid at low temperature and offers resistance limited to bad weather.
Driver : Same type of Oxygen tortured copper, But with a less robust mechanical sheath, which makes it suitable for fixed or semi-mobile installations.
Standards : Complies with the standard in 50525-2-11, with a classification of fire resistance according to IEC 60332-1.
1.3 Comparison and synthesis

| Temperature range | -30°C to +60°C | -5° C to +70 ° C |
| Resistance to mechanical stress | Forte (adapted to frequent flexions) | Average (Avoid high voltages) |
2. Manufacturing process and impact on performance
2.1 H05RR-F manufacturing process
High temperature vulcanization : Treatment by vulcanization at 140 ° C – 160°C, allowing the retication of EPR rubber molecules. This process considerably improves mechanical resistance and temperature holding.
Impact on costs : Vulcanization is a complex process, making the manufacture approximately 30 % more expensive than that PVC cables. However, It increases the lifespan by more than 50 %.
2.2 H05VV-F manufacturing process
Extrusion you PVC : The PVC is melted and then directly extruded around the driver, which allows a simple manufacturing process with low energy consumption.
Boundary : During a low temperature installation, It is necessary to preheat the cable to -5 ° C or more to avoid weakening of the sheath.
This comparison highlights the impact of manufacturing processes on sustainability, Flexibility and resistance to environmental conditions of H05RR-F and H05VV-F, thus facilitating a choice adapted to the technical requirements of your project.
3. In -depth comparison of technical parameters
| Setting | H05RR-F | H05VV-F |
| Driver's shielding option | Naked copper/tinned copper with shielding braid | Only in an unmanned version |
| Abrasion resistance index (FROM 53516) | 1 000 cycles | 500 cycles |
| Radius of curvature (dynamic installation) | 7,5 times the diameter | 15 times the diameter |
| Long -term oil resistance | Excellent (ASTM D471 test validated) | Weak (Not recommended in an oily environment) |
| Environmental level | LSZH (low smoke and halogen free) | Contains halogens (restriction RoHS 3) |
This table highlights the essential technical differences, especially in terms of flexibility, Mechanical resistance and environmental compatibility, allowing an informed choice according to the installation constraints.

5. Installation instructions
5.1 H05RR-F cable installation
Journey : Respect a radius of curvature of 8 times the diameter for a dynamic installation and 6 times the diameter for a fixed installation.
Waterproofing : In wet environments, Use silicone sealed connectors to avoid any water infiltration.
Maintenance in the salt environment : Inspection of the sheath all 3 months to detect possible cracks. A short-circuit incident in a shipyard was awarded to a lack of maintenance.
5.2 Installation of the H05VV-F cable
Low temperature installation : Below -5 ° C, It is recommended to preheat the sheath to avoid any weakening and cracking.
UV protection : In areas exposed to direct sunlight, Add a fireproof protective sheath, which can increase the lifespan by more than 30 %.
Load monitoring : Install an ammeter to monitor the current intensity in real time, thus avoiding the risks of overload and premature aging of the cable.
6. Application environments and specific cases
