Pole Framing and Guying

The main function of a utility pole is to support conductors. Because conductors are heavy, they can pull on a pole with a great deal of force. The equipment on a pole that supports the conductors must be constructed to withstand this force. This course describes methods used to frame a pole, that is, how to install crossarms and other conductor supports. This course also describes methods of supporting a pole using several different types of guying techniques.

Tree Trimming

Trees are common throughout the service areas covered by many utilities. When trees grow into, over, or near energized equipment, they may cause interruptions in electrical service, particularly during storms or strong winds. During an emergency, a tree crew may not be available, and it may not be possible to postpone a job. Lineworkers often handle small tree trimming jobs or work as part of a crew to clear large trees from power lines. This program describes basic methods of tree trimming as well as some of the hazards associated with tree trimming work and precautions that should be taken.
