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. 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 A guy is a brace or cable fastened to the pole to strengthen it and keep it in position. Guy wire is used in various sizes with diameters from 1/ 8 to 1 3/ 4 inches. Alumoweld wire consists of steel wire strands coated with a layer of aluminum to prevent corrosion. Guy Wire The wire, or cable, normally used in a down guy is seven-stranded galvanized steel wire or seven-stranded alumoweld wire. Anchor rods vary in diameter from 1/ 2 to 1 1/ 4 inches and in length from 3 1/ 2 to 12 feet. have an ultimate strength equal to, or greater than, that required by the down-guy assembly. The deadman is not widely used today because of the time and effort required to place it.Īnchor Rods The anchor rod serves as the connecting link between the anchor and the guy cable. It is installed 6 feet deep in loose or sandy type of soil, with an angle of pull for the guy wire and rod assembly equal to 45 degrees. This anchor is made of a 6- to 8-foot-long piece of treated power pole and an anchor rod. These three types of anchors are manufactured and are commonly used because of their ease of installation.įigure 4-1, view D, is called a deadman. Once expanded, the anchor is secure and strong enough to secure the guy.įigure 4-1, view B, shows a plate of a never- creep anchor, and view C shows a screw anchor that is installed using an earth auger. The expanding anchor, the most popular type, as shown inįigure 4-1, view A, is designed to be placed in the ground and then expanded with the aid of the tamping bar. Anchors come in many forms and have different methods of installation.įigure 4-1 shows the most common types of anchors. You must know the type of soil before you can select a certain type of anchor. The guys and braces are used to counter the horizontal strain on the pole caused by conductors, pole-line components, and abnormal loads, such as snow, sleet, or wind.Īnchors Anchors are designed to meet specific soil conditions. Anchors are buried in the ground, and guy wires are connected to the anchors and attached to the pole, or a push brace may be used. To accomplish this, you can use guys, anchors, and braces. The aggitated and loose dirt sitting on the top 6" flight is what is normally found when installing a helix anchor where no compaction is taking place.POLE GUYS When constructing power lines, you will need a means of strengthening poles and keeping them in position. As can be seen by the pictures below, the section of dirt between the 4" and the 6" flight was compacted tremendously more than the dirt sitting on the top flight. Peat, organic silts inundated silts, & fly ashĭuring a pull test the 48" SAF-T-ANCHOR was pulled out of the ground using an anchor pulling device to view the amount of compaction created during installation. Loose fine sand soft-firm clays varied clays & fill Loose to medium dense fine to coarse sand firm stiff clays & silts Medium dense coarse sand & sandy gravels stiff silts & clays Medium dense sandy gravel very stiff to hard silts & clays The reusable SAF-T-ANCHOR can be quickly and easily installed by using an impact wrench (4-5) or high torque power (6-9).ġ) The top flight dissipates electric current adding life to the anchorĢ) Can be installed and removed easily by one person (with impact or manually)Ĥ) Less time to install depending on soil conditionsĥ) Can be used as a permanent or temporary anchorĦ) Anchor will not deteriorate due to electrolysis if copper coatedħ) Guy wire tensioning can be done by screwing anchor in groundĨ) 70% less torque to install than a 10 helix anchor with an 8-3/4 rodĭense clays, sands & gravel hard silts & clays The patented locking action prevents the anchor from unscrewing or backing out when tension is applied.Īvailable in 3/4" and 1 rod with 4 5 6 7 8 9 lengths. What makes this such an effective anchor? Its the patented method of compressing dirt between the top two flights! As the bottom two discs pull the anchor into the ground, the top disc is compressing the dirt creating a wedging effect as it gets pulled into the ground thus creating instant compaction and immediate holding power. THIS SAME ANCHOR CAN BE INSTALLED IN THE FOLLOWING METHODS:
