The power lines are attached to the pole by horizontal strain insulators, either placed on crossarms (which are either doubled, tripled, or replaced with a steel crossarm, to provide more resistance to the tension forces) or attached directly to the pole itself. Dead-end and other poles that support lateral loads have guy … Visa mer A utility pole is a column or post typically made out of wood used to support overhead power lines and various other public utilities, such as electrical cable, fiber optic cable, and related equipment such as Visa mer The standard utility pole in the United States is about 40 ft (12 m) long and is buried about 6 ft (2 m) in the ground.
