Reference project 1. Smelting plant power line in Trondheim – 66 kV 66 kV line Strinda – Fesil Trondheim municipality has built new pedestrian and cycle paths in Lade. This made it necessary to move two masts, VM 56 and EM 51, on the power line to the smelting works. Omega Elkraft project-managed the installation of the new RSB pylons and foundations for Trønderenergi Nett. The pylons and foundations involved many challenges in relation to stresses and ground conditions. VM 56A is a 23-metre corner pylon with an angle of 56 degrees. EM 57A is a 15-metre termination pylon. Both stand on concrete bases set in clay. The line is sized for three Feral 95sP 22/7 power cables and two Fe 30 7×2.30 top lines.
