The minimum distance we can leave between trees and the lines to ensure public safety depends on the voltage of the line, but is a minimum of 5 metres (16ft) to each side of distribution lines (11,000 and 33,000 volt lines). This is approximately the same as the length of an average saloon type car. As the voltages increase for transmission lines, these minimum distances increase. For diagrams and further details on clearances to different voltages, see the safety clearance page.
