Thortec---A New Distribution System

A new and improved system of distribution pole-top construction has been introduced under the name of Thortec. Without the use of an overhead shield wire, it provides lightning protection comparable to fully shielded construction, in addition to high immunity to the effect of lightning strokes terminating on objects adjacent to the line. Thortec is extremely effective in combating aerial contamination and has proved its ability to maintain continuity of service in areas heretofore subject to high outage frequency. This new system is free from interruptions caused by accidental contact of birds or climbing animals. Symmetrical, compact design lends attractive appearance to Thortec lines and permits their use, as opposed to more costly underground construction, in many areas where aesthetic values are highly stressed.
