AX PRO

We Bury our Best Ideas in the Ground

Strikingly Good Results

With the AX PRO you get a grounding conductor in aluminium, with significantly better TCO than its copper equivalent. Moreover, it is much less attractive to thieves. AX PRO is one of the most important and innovative product launches from NKT. After 10 years of development, including several pilot installations, development and patent work, we introduced AX PRO in 2019.

The results are striking: AX PRO has a very high capacity, it withstands corrosion and it is possible to calculate its lifetime.

An innovative approach

The game-changing AX PRO consists of seven individually coated aluminium wires. All wires are cabled into one cohesive product. No additional material is added to keep the product together. If the wires spread apart, it’s only an advantage as the contact surface to the ground increases. This makes the electrical connection to ground even better.

Simply Technically Superior

AX PRO is corrosion protected using a unique polymer. The polymer is highly conductive and mechanically strong. By avoiding bare aluminium in the ground in combination with electric current, you avoid corrosion and the interruption of the current path. Furthermore, AX PRO is the only earth system offering a condition diagnosis facility (life cycle measurement).

Discourages Theft

Another key selling point is the weight of the product. AX PRO is very light per metre in comparison with a copper equivalent. This enables longer delivery lengths with the same weight as the equivalent copper wire. Low weight per metre as well as polymer on the metal results in lower scrap value compared to traditional copper solution, which makes this product less attractive to thieves.
