TRAINING COURSE:
Transmission Structures
Course Category: Transmission and Distribution
Course description: The purpose of this course is to teach how transmission structures are built. It is recognized that transmission structure construction is not a routine part of a lineman’s job in most locations; however, a basic understanding of how this work is done is useful for maintaining transmission lines. The course describes how transmission structure foundations are laid and covers three types of construction methods for erecting transmission structures. At the conclusion of this course, participants should be able to describe how two types of transmission structure foundations are laid. They should also be able to explain how transmission structure construction is planned and describe three ways that transmission structures are erected.
