HVI<sup>®</sup> Lightning Protection System
HVI® Lightning Protection

Keep separation distances easily

15 years’ experience is convincing - Flexibility and safety on the highest level

With the high-voltage-resistant, insulated conductors of the HVI® system, it is easy to keep separation distances.
The lightning current carrying core of these conductors is coated with insulating material in such a way that the required separation distance to other conductive structural features or electric lines and pipes is easily maintained. There are no further measures required.


More and more important for modern buildings: Appearance and design

HVI® conductors can be installed behind the façade, HVI® conductors with grey sheathing can even be painted the same colour as the building.
For you this means: optimal adjustment to the architecture of the building and completely new design possibilities.

By the way:

When it comes to creating equipotential surfaces, the DEHN portfolio provides everything from one source.

HVI® lightning protection - Your benefits at a glance

  • Keep separation distances
    You install directly next to conductive structural parts or electric lines or pipes
  • Easy to mount
    With the modular components and special tools, such as the HVI®-Strip, mounting is safe, quick and easy
  • Integration in the architecture of the building
    The grey HVI®Conductor and the HVI®light conductor can be painted the desired colour
  • Flexible when retrofitting
    Subsequent installation on the roof is possible WITHOUT adapting the lightning protection system
  • Use in Ex areas
    For Ex zone 2 and 22: All HVI® versions
    For Ex zone 1 and 21: HVI® and HVI®power

Special software for easy calculation

Tip: You want to save time? Calculating separation distances is quick and easy with the DEHNsupport Toolbox software. It facilitates the numerous calculations required for a professional lightning protection system. Alongside the calculation of separation distances, you will also find modules on the themes risk management, length of air-termination rods, length of earth electrodes and product selection.
