have an ultimate strength equal to, or greater than, that required by the down-guy assembly. Anchor rods vary in diameter from 1/2 to 1 1/4 inches and in length from 3 1/2 to 12 feet.
The wire, or cable, normally used in a down guy is seven-stranded galvanized steel wire or seven-stranded alumoweld wire. Alumoweld wire consists of steel wire strands coated with a layer of aluminum to prevent corrosion. Guy wire is used in various sizes with diameters from 1/8 to 1 3/4 inches.
A guy is a brace or cable fastened to the pole to strengthen it and keep it in position. Guys are used whenever the wires tend to pull the pole out of its normal position and to sustain the line during the abnormal loads caused by sleet, wind, and cold. Guys counteract the unbalanced force imposed on the poles by dead-ending conductors; by changing conductor size, types, and tensions; or by angles in the transmission or distribution line. The guy should be considered as counteracting the horizontal component of the force with the pole or supporting structure as a strut resisting the vertical component of the forces.
DOWN GUY. - A "down guy" consists of a wire running from the attachment near the top of the pole toContinue Reading
