Comparison between the H07VU and other similar cables
A summary table would quickly visualize these differences.
| Characteristic | H07VU | H07VR | H07WK | H05VU |
| Driver type | Rigid drivers | Semi-rigid drivers | Flexible conductors | Rigid drivers |
| Flexibility | Not very flexible, Designed for fixed applications | Intermediate flexibility, For mobile and fixed installations | Very flexible, Suitable for mobile installations | Not very flexible, Designed for fixed applications |
| Applications principales | Installations fixes (domestic, industrial) | Installations fixes et mobiles (Wiring in modified environments) | Mobile installations, especially for equipment requiring flexibility | Small fixed and domestic installations |
| Tension nominale | 750V (common use, domestic and industrial installations) | 750V (common use, installations mobiles et fixes) | 750V (common use, For equipment requiring increased flexibility) | 500V (For smaller and less demanding applications) |
| Isolation | PVC (moisture protection, heat) | PVC (moisture protection, heat) | PVC (moisture protection, heat) | PVC (moisture protection, heat) |
| Standards | Compliant with European standards (IN 50525) | Compliant with European standards (IN 50525) | Compliant with European standards (IN 50525) | Compliant with European standards (IN 50525) |
Summary of the main differences
H07VU vs H07VR : The H07VR is more flexible than the H07VU, thanks to its semi-rigid drivers, This allows it to adapt to mobile installations or environments requiring a certain mobility.
H07VK vs H07VU : The H07VK is designed for more flexible applications, with drivers who are better resistant to mechanical constraints, While the H07VU is intended for fixed installations without the need for flexibility.
H07VU vs H05VU : The H07VU offers a capacity higher tension (750V), which makes it more suitable for larger industrial and domestic installations compared to the H05VU (500V), which is intended for smaller installations.
How to choose the H07VU cable adapted to your project ?
The choice of the right cable is based on several criteria :
Cable section : It must be adapted to the provided electrical load.
Length : The longer the cable, The more the loss of tension is significant.
Environmental conditions
Extreme temperatures.
Presence of humidity or chemical agents.
Respecting local standards is also essential to guarantee the safety of the installation.
Environmental analysis of cable H07VU
Ecological impact
Recyclable materials : The copper used in conductors is completely recyclable. The PVC, Used for insulation, can also be recycled, Although its treatment is more complex than that of copper.
Comparison of standard PVC insulation and LSZH
PVC standard : Offers effective protection, But produces toxic gases in the event of a fire.
LSZH (Low Smoke Zero Halogen) : Emits less smoke and no halogenated gas during combustion, thus offering a safer solution in the event of fire, Although more expensive.
Recycling initiatives
Used cables can be recovered to extract copper and other materials, thus reducing dependence on the extraction of new resources and the carbon footprint.
Installation and cable maintenance advice H07VU
