Rigid Cable
The rigid cable is a solid or loosely twisted copper electrical conductor, which easily retains its shape after installation. Compared to flexible cable, it offers better mechanical strength and stable installation over time. According to the NORME IEC 60228, Rigid cables are mainly classified into two categories :
- Class 1 : massive conductor (a single strand), the most rigid and economical, ideal for fixed installation in conduit or panel (par ex. H07V-U, Nya).
- Class 2 : rigid stranded conductor (cable), slightly more flexible during installation while maintaining good mechanical strength (par ex. H07V-R, Nyy).
Thanks to this structure, the rigid cable adapts perfectly to long-term fixed installations. We particularly recommend it for residential buildings, tertiary and industrial, as well as for low voltage power distribution. At ZMS Cable, We offer a wide range of rigid cables complying with IEC standards, VDE et NF, tels that H07V-U, H07V-R, Nyy, N2xy, you n2xh.

ZMS Consulting :
From a technical point of view, the rigid cable offers better mechanical strength and generally lower cost for long lengths, while the flexible cable facilitates installation in confined spaces or in the presence of repeated movements. For the same project, it is not uncommon to combine the two : rigid for main distribution, flexible for final connections.
For installations requiring more flexibility, check out our flexible cables.
FAQ – Rigid Cable
Class 1 or Class 2 : how to choose between the two ?
The choice mainly depends on the installation method and the budget.. The class 1 (massive soul) is the most economical to manufacture and offers excellent mechanical stability, but it is more difficult to handle on large sections. The class 2 (wired soul) costs slightly more to produce, but it is easier to pull into the conduits, especially on large sections or paths with several bends.
ZMS Consulting : For wiring panels and small sections, the class 1 remains the standard. As soon as the section exceeds 16-25 mm² or that the route has many bends, the class 2 significantly facilitates installation.
Can rigid cable be buried directly in the ground ?
Non, not in the general case. Rigid cables like and H07V-U are designed for installation under conduit, chute or board, and do not have the mechanical protection necessary for direct burial. Some sheathed references like le NYY tolerate installation in a buried sheath according to local regulations, but remain to be distinguished from a cable designed specifically for direct burial.
ZMS Consulting : For buried installation without sheath, we recommend armored cable, whose construction (metal armor, reinforced sheath) is specifically designed to withstand ground stress.
What is the difference between H07V-U and NYY ?
And H07V-U is a rigid single-wire conductor with PVC insulation, Without outdoor sheath. Its rated voltage is 450/750 V and its design is suitable for installations where the conductor is already protected by a conduit, a chute or equipment.
Le NYY is a multi-conductor power cable, with insulation and PVC outer sheath, generally used to 0,6/1 kV. Its sheath provides additional protection against mechanical stress and the installation environment.
ZMS Consulting : don't choose only based on the number of drivers. First check the rated voltage, the method of installation and the level of mechanical protection required. The H07V-U is a conductor to be integrated into a protected wiring system, while the NYY is a complete cable solution with its own jacket. If the installation requires a cable that can be laid without additional mechanical protection, the H07V-U is generally not the appropriate choice.
For a detailed comparison (isolation, sheath, recommended installation), consult the complete table on page H07V-U。
Which section (mm²) is available for ZMS rigid cables ?
According to the standard IEC 60228, section range differs depending on class : the class 1 (massive soul) covers sections of 0,5 mm² à 1200 mm², while the class 2 (wired soul) allows you to go up to 2500 mm² for large distribution sections. ZMS CABLE manufactures rigid cables that comply with IEC and other standards. We can also manufacture tailor -made cables to meet your residential installation needs, commercial and industrial.
ZMS Consulting : For weak sections (panel wiring, indoor distribution), the class 1 is the standard choice. For large sections in low voltage distribution, the class 2 offers more manufacturing and installation flexibility.
Does the rigid cable comply with European standards (CE, IEC, VDE, NF) ?
Oui. Our rigid cables are manufactured in accordance with standards IEC (IEC 60227, IEC 60502-1), VDE (From vde 0276-604) and N.F. (NF C 32-321 for the U-1000 R2V), according to the reference concerned. Each batch is tested before shipping, with test reports available on request, and our cables bear the CE marking when required by the regulations of the destination market.
