110-Kv. transmission line for oak grove development of portland railway, light and power company: Transmission line construction in crossing mountain ranges

R.J.C. Wood: We have encpuntered some little trouble in crossing mountain ranges in snow countries, supposedly due to the loss of the snow or sleet load from a span and the conductor coming in contact with the one above it. On the double-circuit steel tower line, in question, the conductors are offset a foot and a half from the vertical plane of the one above it. We have had considerable discussion as to just what happens to cause these conductors to come together. One theory being that the sleet falls off the one span and still remaining on the adjacent span, the lighter span is pulled up into the one above it.
