150 kV Transmission Tower, Nunspeet

Craftsmanship for a future-proof energy grid

The energy transition places increasingly demanding requirements on the infrastructure used to transport electricity. New connections, higher-capacity grids and upgraded substations require reliable technical solutions and precisely engineered steel structures.

Ready for growing electricity demand

On behalf of Qirion, TruSteel Industry is working on a new high-voltage transmission tower for the substation on Hullerweg in Nunspeet. The tower is part of the upgrade of the existing overhead high-voltage connection between Harderwijk and Nunspeet, increasing the voltage from 50 kV to 150 kV.

Electricity demand continues to grow, as does the amount of energy fed back into the grid from locally generated sources. Expanding and upgrading the existing infrastructure is essential to prepare the electricity grid for these developments. By upgrading this connection, transmission capacity is increased and the reliability of the energy grid is maintained.

For TruSteel Industry, this is an exciting project that brings together specialist steel construction and the development of the Dutch energy infrastructure.

A distinctive high-voltage tower

The new tower in Nunspeet stands out because of its unique steel construction. According to the available project information, only two comparable structures have been built in the Netherlands to date. This makes the project a distinctive addition to our portfolio of specialist steel structures.

The design of this high-voltage tower is carefully tailored to its function within the electricity grid. The loads imposed by the conductors, the forces acting on the tower and the required connection points all influence the design and execution of the steelwork.

The tower is designed to support the high-voltage conductors in the correct positions and safely transfer the associated forces to the structure and its foundation. Its design and the precise connections between the individual steel components require a high level of accuracy during both fabrication and assembly.

According to the available project information, only two comparable structures have been built in the Netherlands to date.

Maintaining control over quality

For this project, we are responsible for constructing the new high-voltage tower, including its protective coating and trial assembly at our facility in Heeg. By carrying out these activities under one roof, we maintain control over quality and carefully prepare for the final installation.

Precision is essential when constructing a structure of this kind. All steel components are carefully manufactured to ensure that the structure meets the design specifications and can be assembled correctly on site. During the trial assembly, the structural components are temporarily fitted together in advance. This allows us to verify that all components align correctly and that the connections meet the design requirements. Any deviations can therefore be identified in good time, before the structure is transported to the project site.

Contributing to a reliable energy supply

This project demonstrates how specialist steel construction contributes to these developments. By taking responsibility for the construction, protective coating and trial assembly of the tower, we contribute to expanding the electricity grid and preparing the infrastructure for a reliable energy supply.
