ASTM standard stay wire, guy wire, Stranded Galvanized Steel Wire Application: The galvanized single steel wires or stranded steel wires are suitable for cores of ACSR to improve its tensile strength. And they can also be used in the aerial transmission line as the line material of ground connection to avoid the lightning strike. Construction: The single wires are concentrically stranded and wrapped helically around a central wire. Specification:

ASTM Standard Stay Wire, Guy Wire, and Stranded Galvanized Steel Wire are commonly used components in the construction of overhead power transmission and distribution systems, as well as in other applications that require structural support and stability.
Stay Wire: Stay wire, also known as guy wire, is a tensioned cable or wire used to provide stability and support to utility poles, towers, or other structures. It helps prevent excessive swaying, sagging, or leaning of the structures under various loads and environmental conditions. Stay wires are typically made of galvanized steel for corrosion resistance and strength.
Guy Wire: Guy wire is another term used for stay wire. It is commonly used in the context of supporting tall structures, such as utility poles, transmission towers, or communication masts. The guy wire system includes multiple stay wires attached at specific angles to provide stability and counteract the forces acting on the structure.
