Product Introduction
Galvanized steel wire strand is made of high-quality carbon steel wire coils through a series of processes such as heat treatment, shelling, washing, pickling, washing, solvent treatment, drying, hot-dip galvanizing, post-treatment and then twisting.
Galvanized steel wire strand is usually used as ground wire for overhead transmission lines to prevent lightning from striking the wire and shunting the lightning current. It can also be used to strengthen the overhead communication cable to bear the cable’s self-weight and external load.
The galvanized steel wire strand we provided has the following characteristics:
1) The zinc layer is uniform, continuous, bright and does not fall off.
2) Stranded tightly, without jumpers, s-shaped and other defects.
3) Round appearance, stable size and large breaking force.
We can provide galvanized steel wire strand in various structures to meet the requirements of BS 183 and other standards.
Application
Mainly used as ground wire for overhead transmission lines to prevent lightning from striking the wire and shunting the lightning current. It can also be used to strengthen the overhead communication cable to bear the cable’s self-weight and external load.
