Galvanized Wire For Cable Armoring 2.5mm 3.0mm
Low carbon steel wire for armored cable is generally the following standard
Galvanized low carbon steel wire for overhead communication has strict requirements for resistivity, so the chemical composition of raw materials must ensure that the resistivity of the finished wire is qualified. The surface treatment, drawing and heat treatment process of steel wire is similar to that of general purpose low carbon steel wire, but requires a thicker zinc layer, and in some cases, passivation treatment after galvanization, i.e., the galvanized steel wire is dipped into a mixed solution of chromic acid, sulfuric acid and nitric acid to form a passivated protective film of rainbow color or light yellow, light green, light red and other mixed colors on the surface of the zinc layer to further improve the corrosion resistance of the wire. The steel wire is annealed before galvanizing. Finished galvanized low carbon steel wire with a tensile strength of 345 to 490 MPa for armored cable also requires a thicker zinc layer, and some also require passivation treatment after galvanization.
