TenneT Netherlands’implementation of the ACCC® AZR Conductor for this project marks a significant advancement in the region’s energy infrastructure. This innovative conductor, ensures a robust and reliable power supply under heavy ice and wind conditions.
TenneT’s decision to standardize on the ACCC Warsaw profile across its network simplifies maintenance, inventory and enhances efficiency. The collaboration between CTC Global and stranding partner Midal has yielded a conductor that not only meets TenneT’s future capacity requirements, but also delivers enhanced performance in environmentally challenging areas.
Due to the low tower profiles, sag mitigation under all conditions was a critical feature of the project. To minimize creep, all spans were pre-tensioned to 1.5 X EDS during installation.
Dr. Eric Bosze, CTC’s Director of Conductor Materials Research, emphasized the benefits of the ACCC AZR Warsaw: “This conductor adds significant capability and cost-effectiveness to CTC’s proven ULS (Ultra-Low-Sag) core variants already deployed in Northern Europe, particularly for areas where high wind and ice loads can be expected.”
The deployment of this conductor is particularly critical for the northern regions of Drenthe, Groningen, and the eastern part of Friesland. For these areas, ACCC® AZR Warsaw is the ideal choice due to its resilience against heavy ice loads. Meanwhile, the standard ACCC® Warsaw conductor, with its high-strength carbon core and soft annealed aluminum, effectively meets the needs of the national grid operator for the rest of the country.
This project reinforces the reliability of the power grid and supports the ongoing transition to sustainable energy sources in the Netherlands, ensuring a secure future for the region’s energy supply.
