Galvanized steel wire for steel core aluminum stranded wire (GB/T3428-1997)

The introduction of galvanized steel wire for steel core aluminum stranded wire The steel wire used for the steel core aluminum stranded wire is the galvanized steel wire stipulated in GB/T3428-1997.Standard. The galvanized steel wire used for the steel core aluminum stranded wire has the excellent characteristics of corrosion resistance, wear resistance, fatigue resistance and stable electrical conductivity, so it is suitable for the transmission of electrical energy. Galvanized steel wire can be divided into hot-dip galvanized steel wire, cold-dip galvanized steel wire, electro-galvanized steel wire, etc., and its variety is relatively abundant. Hot-dip galvanized steel wire is the most common type of galvanized steel wire, and the common ones are GB/T3428-1997. The galvanizing process of hot-dip galvanizing is: the steel wire is heated to a certain temperature, cleaned, immersed in a molten zinc solution, and then cooled, resulting in a uniform and complete zincon layer formed on the surface of the steel wire. Hot-dip galvanized steel wire has the advantages of large bonding capabilities and resistance to rust, making it a popular galvanized steel wire for may industrial and commercial uses. Cold-dip galvanized steel wire is also known as electrolytic galvanized steel wire. The cold galvanizing process is very similar to the galvanization process of hot-dip galvanizing steel wire. The difference is that in the galvanization process, the steel wire is submerged in a metal liquid containing zinc, resulting in a uniform zinc layer on the surface of the steel wire. The cold-dip galvanized steel wire has a higher corrosion resistance than the hot-dip galvanized steel wire, and its quality and performance are of course better. However, due to the lack of a thick zinc layer, the price of the cold-dip galvanized steel wire is slightly higher. The electro-galvanizing process is another kind of galvanizing technology, which uses electrochemical reaction to form a uniform and complete zinc layer on the surface of the steel wire. The zinc layer formed by the electro-galvanized process is thinner than the zinc layer formed by hot-dip galvanizing, but has better corrosion resistance and greater adhesion. Electro-galvanized steel wire generally has a very regular appearance, and because of its attractive silvery sheen, it is widely used in the manufacturing of arts and crafts. Galvanized steel wire has been widely used in many fields due to its excellent characteristics. It is very suitable for the manufacture of steel core aluminum stranded wire and is a very important material for the production of electrical products. It can not only reduce the transmission loss of electricity, but also ensure the safety of the power system. Therefore, galvanized steel wire is an irreplaceable material for the production of electrical products.
