maintenance must be possible on one circuit while the other three are in service.

In updating the Wintrack design to accommodate the 4-circuit 380 kV, 4000 A lines, two additional considerations had to be taken into account: In particular, two 4-circuit 380 kV, 4000 A lines were planned to run from Diemen to Eemshaven in the northern Netherlands (NW380) and from Borsele to Tilburg in the southwest Netherlands (ZW380).ĭNV GL was asked by TenneT to assist in a feasibility study on the development of the 4-circuit 380 kV Wintrack towers. However, projected grid utilisation in the Netherlands for the coming years suggested that 4-circuit 380 kV towers would also be required. The original Wintrack tower design included a double 380 kV circuit and a combination line of two 380 kV circuits and two 150 kV circuits. This article, by Peter Kolmeier of DNV GL Kema, reported on a subsequent upgrade to the original Wintrack design.

This first Wintrack design was presented at the 2013 INMR WORLD CONGRESS in Vancouver, Canada. And during the course of 20, a high-voltage (380 kV) line will be constructed with almost 160 Wintrack tower sites linking Bleiswijk, Vijfhuizen and Beverwijk. Subsequently, a complete high-voltage line from Wateringen to Bleiswijk, comprising 33 Wintrack tower sites, was rolled out in 2012. In 2010, the first three of these Wintrack towers were erected and commissioned along the A12 motorway, between Krimpen and Bleiswijk. The project started in 2006, with the aim of developing a new family of transmission towers that is more visually appealing to the general public, has a smaller electromagnetic (EM) field zone and minimises the right of way for overhead lines. With these concerns in mind, TenneT, the Dutch national transmission system operator (TSO) asked DNV GL to assist it in developing an innovative new transmission tower family. Magnetic fields: there is increasing concern among the public over the possible effects of living close to high magnetic fields.

Space: in densely populated areas, it is increasingly difficult to find room for large transmission towers and the conducting lines that connect themģ. Aesthetics: transmission towers are often considered a blot on the landscapeĢ. However, while demand for electricity is constantly increasing, the general public is less and less accepting of the transmission towers that carry it.Ĭoncerns over transmission towers fall into three basic areas:ġ. Electricity transmission towers (or ‘pylons’) and overhead lines are perhaps the most familiar face of electricity transmission and distribution to the public.
