Hyndla spoke at REN’s annual regional power grid conference 2020
During REN’s annual conference adressing the Norwegian regional power grid last week Managing Director of Hyndla, Magnus Kjepso Halvorsen, had the opportunity to speak on the importance of calculating tower behavior under tension with the correct stiffnes.
This is especially important with new materials being implemented into the power grid like FRP/composites and aluminium, which both have different stiffness compared to traditional wooden poles.
Accurately calculating how a series of towers bahave with the correct siffness is a core design principle behind Hyndla’s aluminium towers and as Halvorsen explains: “Stiffness can be as important as strength in load-bearing towers and it plays an increasingly important role as we build taller and taller towers with greater distances between them.”
“The design planning tools used to design power lines today mainly focus on strength, so it is important that the practical and theoretical experience gained from years of building power lines is transferred in a safe way when we shift to the use of new materials. New regional grid power lines are often built taller and with longer spans and it is important to understand how and why the models and tools used to design these lines work.”
We use Impetus Afea, a non-linear explicit finite element tool, to correctly calculate the stiffness of our towers and how they behave together.
REN is the orgnaization standardizing materials and methods for the Norwegian TSOs. They publish guidelines, develop tools, and host courses and conferences.
