The galvanized single steel wires or stranded steel wires are suitable for cores of ACSR to improve its tensile strength. It’s still usually use for steel core for stay wire or guy wire. And they can also be used in the aerial transmission line as the line material of ground connection to avoid the lightning strike.
Bare concentric-lay-stranded conductors are made from bare, hard-drawn, round, aluminum clad steel wires for general use of electrical purposes. The galvanized steel wire made from fully-killed steel with a carbon content of 0.6%, it is galvanized by either a hot dip or electrolytic process to give a zinc coating layer. Tensile strength and zinc-clad of steel wire have different grades.
The galvanized steel wire strand available in class "A", "B" and "C" galvanizing, "A" being the least heavy and "C" being the most heavy, each grade corresponding to different tensile strength. Its low cost and ease of production makes galvanized steel wire ideal for mass produced corrosion resistant wire products, which is indispensable in industrial, agricultural.
