A guy wire is a tensioned cable used in the construction and support of overhead transmission lines. It is also known as a guy rope or a guy cable. It helps to provide extra stability and support to the structures to prevent them from leaning or toppling over. Guy wire helps to prevent the damages caused by load from wind, ice and weight of transmission lines. It installs at an elevated angle from the structure to the ground. This helps to ensure the supported structure remains stable and upright under various conditions. South America requires the use of high-quality guy wires to ensure the reliability and stability in the challenging terrains. The examples of guy wires include stranded guy wire, solid, aluminum, helical and extra high strength guy wire. They find use in applications such as telecommunications, wind turbines, coastal structures and construction support.
