GSW Wire-Galvanized Steel Wire/Strand Bare concentric-lay-stranded conductors are made from bare, hard-drawn, round, aluminum clad steel wires for general use of electrical purposes.
Messenger wires, overhead ground or static wires for distribution and transmission lines, communications and signal lines, antenna towers, masts, stacks and other structures
ASTM A-475，IEC 61089，BS 183
Tensile strength and zinc-clad of steel wire have different grades.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.
