Conventional high-voltage transmission lines sag considerably between towers. As the lowest point of sag needs to have a certain minimum distance to the ground depending on the terrain, conventional towers are very high. Furthermore, low-sag conductors can swing heavily to the side in case of strong winds, defining the width of the buffer strips along the line. The further the conductors swing, the wider the corridor. In order to reduce both sag and swing, every component of the electricity transmission system has to be researched and modified: for compactLine, the transmission tower, the conductor arrangement, conductors and earth wires are all being reimagined.
