AN UNDERHUNG INSULATOR


The Locke Insulator Manufacturing Company of Victor, N. Y., is now making a suspension type insulator which is sometimes called the underhung insulator. It consists essentially of several unit insulators of moderate size attached mechanically so as to form a string of insulating units of great mechanical and electrical strength. Its main advantage lies in the fact that it permits indefinite expansion

by the addition of units, and as the distance between the transmission line wire and the earth is very great, static strains are reduced to a minimum, whereas in the ordinary pin type of insulator there is considerable static strain between the line wire and support, due to the fact that they are ordinarily not more than three inches apart. As its name signifies, the suspended insulator depends from the under side of the cross arm or structural steel support. The method of application is clearly shown in the accompanying illustrations.
