The purpose of this course is to teach how to replace conductors in an existing line with new conductors. The situation described is one that often occurs when it is necessary to increase the size of the conductors in a line. This interactive online course demonstrates how to install the new conductors, parallel them with the existing conductors, and remove the old conductors. The importance of maintaining the proper clearances and the importance of maintaining the integrity of the existing line are explained. Safety is emphasized throughout the course.

At the conclusion of this course, participants should be able to plan a replacement job and demonstrate how to perform the major steps involved in doing the job. They should be able to install temporary crossarms, transfer lines, pull and sag new lines, parallel a new line with an existing line, and remove old conductors.
