Wintrack Pylons

Bleiswijk, The Netherlands

VolkerWessels Telecom - Network Solutions has been awarded a contract for the placement of 450 Wintrack masts for TenneT. This represents a new step into the world of energy for VolkerWessels. A new market with a reliable product. Indeed, designing and building masts is Network Solutions' core business.

Lattice Pylons

The current high tension pylons - lattice pylons - are designed to last 100 years. These pylons are solid, transparent and easy to maintain. A drawback is the magnetic field. In the case of lattice pylons, the magnetic field extends approximately 150 metres to both sides of the pylons. In other words, in an area of 300 metres around the pylons no homes, schools, day care centres, etc may be built.

Smaller Magnetic Field

TenneT, together with KEMA has developed a new configuration for suspending electricity-conducting cables. This reduces the magnetic field to 75 metres on either side of the pylon. However, this new configuration cannot be suspended from traditional lattice pylons. TenneT has commissioned an agency to design a new pylon. This has resulted in a pylon known as Wintrack that consists of two slim tapered poles that to the eye appear to be standing apart. With this shape the pylons fit well into the landscape. The pylons furthermore requires low maintenance, due to its simple smooth structure.


The requirement during the tender was to develop the design in detail within the specified guidelines. VolkerWessels Telecom succeeded in designing a round conical pylon with minimalistic details. VolkerWessels Telecom was judged the best submission on the basis of these points and this together with a competitive price resulted in the award of a framework contract. For this project, VolkerWessels Telecom is working closely together with VDL, the company supplying the pylon. Of course the assembly of the pylons is performed by our own specialised high-rise workers. The first two pylons were delivered on 22 April 2010 in Bleiswijk, the Netherlands.
