Description :

　　DaZheng has good corrosion resistance and aluminum clad steel stranded wire JLB20A-100 overhead transmission transformer

　　Performance characteristics of aluminum clad steel stranded wire

　　1. Good corrosion resistance

　　2. High bonding strength between aluminum and steel

　　3. Compared to galvanized steel wire of the same specification, it has a lower specific gravity and resistivity

　　4. Good lightning thermal stability, strong overload capacity, and can be continuously used in high temperature environments

　　5. Without increasing project investment, it can facilitate the operation and maintenance of the line, reduce line losses, and improve the efficiency of project investment

　　Aluminum clad steel stranded wire can be used as a reinforcing core for wires and as a ground wire in power transmission and distribution systems, especially in large-span engineering. The application of aluminum clad steel stranded wire with different conductivity shows its advantages. Aluminum clad steel cored aluminum stranded wire replaces steel cored aluminum stranded wire on high-voltage transmission lines. In the application of optical fiber composite overhead ground wire (OPGW optical cable), aluminum clad steel wire is used as a reinforcing wire material both domestically and internationally. On electrified railways, it can be used as both general load-bearing cables and current carrying load-bearing cables, as well as for power transmission and distribution. Aluminum clad steel wire is widely used in the protective nets of high-speed electrified railways abroad.

　　In recent years, with the widespread application of OPGW fiber optic composite overhead ground wire cables, the matching good conductor ground wire aluminum clad steel stranded wire is also increasingly used in overhead ground wires. The advantage of using aluminum clad steel stranded wire as a ground wire is that it can effectively share the single-phase short-circuit current of the OPGW installed together with it; At the same time, it also has many advantages on high-voltage lines, such as reducing power frequency voltage, minimizing secondary current, and reducing interference and dangerous effects on communication lines; In addition, it also has anti-corrosion properties compared to conventional galvanized steel strands, making it particularly suitable for coastal areas and areas with severe industrial pollution and corrosion.
