Controlling Insulation Difficulties in the Vicinity of Great Salt Lake

The difficulties encountered in maintaining a sufficiently high degree of line insulation on long communication circuits in the vicinity of Great Salt Lake, Utah, are dealt with in this paper and a review of the study and solution of the problem of controlling the insulation is made. Leading up to this is a description of observations on about 40 mi. of line over a part of the Great Salt Lake Desert known as the mud flats west of the Lake. The description also covers observations on other lines north of the Lake. The object of these studies was to ascertain the variations in the line insulation caused by different weather and temperature conditions in each of these routes. It was necessary also to determine which route would be better for constructing the central transcontinental communication circuits which were about to be built at that time for extending service to provide telephone connection between points on the Atlantic and Pacific coasts.
