    Galvanized Steel Wire Stranded Galvanized Steel Wire StrandedGalvanized Steel Wire StrandedGalvanized Steel Wire Stranded

Application

Galvanized steel strand is made of 7,19 or 37 wire galvanized steel wire, It’s usually use for steel core for ACSR, stay wire or guy wire.It is widely used for transmission poles and railway track signals, And they can also be used in the aerial transmission line as the line material of ground connection to avoid the lightning strike.

Structure

Galvanized steel wire made from fully-killed steel with a carbon content of 0.6% has a UTS of 1.31-1.39Gpa, It is galvanized by either a hot dip or electrolytic process to give a zinc coating mass of 200-260g/m2.

Standard

Products can be manufactures according to IEC standard, ASTM standard,BS standard, DIN and other standard and customizable cable.
