GSW-Galvanized Steel Wire Conducutor

GSW WIRE APPLICATION

Galvanized steel wire also names GSW Wire ,Messenger Wire, Overhead Ground or Stay Wire, Guy Wire, GI Wire
Galvanized steel strand wire can be used as ground wire of overhead line, but also can be used as structural cable, supporting cable, cable, block cable and cable reinforcement core. It is made of wire twisted together. There are mainly ASTM standards, BS standards, IEC standards and other production standards. It is widely used in energy, construction, bridge, water conservancy and geotechnical engineering.

STANDARD :

ASTM A475, ASTM A363, IEC 61089 BS183:1972 and ect.Other International Standard.

CONSTRUCTION :

1.The single wires are concentrically stranded and wrapped helically around a central wire.
2.Zinc-coated grade of steel strand wire /guy wire : Class A ,Class B and class C.
Concentrically stranded Galvanized steel wire strand available in class “A”, “B” and “C” galvanizing, “A” being the least heavy and “C” being the most heavy.
