For years, NYY cables have been a economic, reliable, fixed-installation standard all over Europe. But…
POWERFLEX® RV-K, the cable that solves any curve in the routing with its high flexibility
POWERFLEX® RV-K cables with class 5 conductors and XLPE insulation are becoming the preferred choice for industrial installations across Europe. Is a flexible power cable designed to circumvent the difficulties of complex installation layouts. Moreover, thanks to the design of its materials, it can be installed in all types of environmental conditions (wet and dry areas, outdoors, buried and even submerged in water).

WHY EUROPE IS SWITCHING FROM NYY & N2XY TO RV-K CABLES
For years, NYY, N2XY, R2V, YmVK, XV and XVB-F2 cables have been a economic, reliable, fixed-installation standard all over Europe. But what if you could have the same advantages with unparalleled flexibility and better electrical performance? RV-K cables with class 5 conductors and XLPE insulation are becoming the preferred choice for industrial installations across Europe.
Let’s break down why making the switch to RV-K is a cost-effective game-changer for your industrial installations.
A CABLE DESIGNED TO MAKE THE INSTALLER’S LIFE EASIER
POWERFLEX® RV-K is an ultra-flexible power cable designed to meet the most demanding industrial requirements. Its great flexibility is great news for installers, who will find it simplifies their work when installing the cable in complex layouts.
This ease of installation not only influences the work of the technician carrying out the work, the flexibility of the cable also minimises the costs of the project, as the flexibility of the cable will save a lot of time spent on the project and consequently reduce the cost of labour. This advantage is particularly noticeable in large cable cross-sections, e.g. 4×150 mm2 cables.
Also noteworthy is its ability to not crack under vibration due to its flexible copper conductors.
POWERFLEX® RV-K TECHNICAL CHARACTERISTICS
Above all, the cable stands out for its extreme flexibility and a higher thermoelectric capacity of its conductor compared to other PVC-insulated conductors.

POWERFLEX® RV-K CABLE OVERVIEW
- Class 5 Flexible Conductors: This design makes the cable incredibly easy to handle, route around tight corners, and pull through conduits. This directly translates to reduced installation time and lower labour costs. The advantage is massive on large projects using big cross-sections (e.g., 4×150 mm²).
- XLPE Insulation: Unlike standard PVC, XLPE can withstand higher operating temperatures (up to 90°C). It also offers better resistance to crushing, impact, and chemicals, ensuring a longer service life in harsh conditions.
- Versatile Installation: The POWERFLEX® RV-K is designed for use in a wide range of environments—from wet and dry areas to outdoors, buried, or even submerged in water (AD8 certification).
- From a trusted manufacturer: Top Cable is a leading European manufacturer with a proven track record of producing high-quality, reliable RV-K cables like the POWERFLEX® RV-K.
Always check the cable’s certification for its specific CPR fire performance to ensure it complies with your local building and safety regulations.
APPLICATIONS WHERE IT IS ADVISABLE TO USE THE CABLE
POWERFLEX® RV-K cable, manufactured by Top Cable, is especially recommended in demanding circuits thanks to its flexibility. It is also very suitable for outdoor, as well as in offices, production plants, laboratories, etc.
- Industrial use.
- Outdoor lighting.
- Energy distribution in industrial and commercial buildings.
- Connection of electrical equipment.
- False floors or technical channels installations.

- Tertiary facilities (hotels, offices, warehouses).
- Suitable for installation on cable paths, in conduits, in chute or full walls.
It can be installed in the open air, in conduit and/or buried in indoor and outdoor installations.
WHEN RV-K FLEXIBLE XLPE/PVC CABLE IS PREFERRED?
The demand for energy-efficient and durable infrastructure is pushing the market towards higher-performance materials like XLPE over standard PVC.
The total cost of ownership (including installation labour) is a key decision factor, favouring flexible cables that reduce installation time by up to 30% on complex routes. Class 5 conductors are becoming the preferred choice for industrial installations across Europe due to their cost effectiveness, flexibility and ease of installation.
- For easy and fast Installation: it means less physical effort and time required for your team.
- For easier and safer cable termination: flexible strands are simpler to fit into terminals and connectors securely.
- To reduce damage risk: Less strain on the cable during installation means a lower risk of internal conductor damage, enhancing the long-term reliability.
- High-density cabling environments: In dynamic environments like modern data centers, Class 5’s flexibility allows for easier updates and scalability, making it a more suitable choice for high-density cabling.
